Protection Functions

The module provides full protection for motor by supervising three phases voltage, three phases

current, earth fault current, startup time, the state of contactors and the state of main switch.

Responding of protection functions is based on the parameters given by user. The operation of

separate functions is independent thus protection functions can be active at the same time but

the one which indicates the situation first will give a trip for motor.

According to the application, all kinds of protection can be enabled, disabled by the upper level

system or MCU parameter setting tool, also the protection characteristics can be adjusted.

MC510 offers the following protection and supervisory function.

Thermal overload protection

Stall protection

Long start protection

Phase failure protection

Unbalance protection

Thermal Overload protection

Thermal overload protection (TOL) protects the motor against overheating.

The motor thermal condition is simulated by a calculation. The result of the calculation is stored in a

thermal register and can be reported via operator panel or fieldbus interface.

Calculation is accomplished in a different motor operation conditions, principle presented below,

thermal increase and decrease are simulated by TOL protection function for running and stopped

motor.

Fig 22 Principle picture of motor thermal simulation

MC510 simulates thermal conditions in the motor for all operating modes (Running or Stopped).

This permits maximum utilization of an installation and assures safe protection of the motor.

Thermal overload protection simulation accounts for the temperature rise of both the stator

winding and the iron mass of the motor, it gives thorough consideration on the effect of motor

overheating due to three phase unbalance during the simulation calculation of motor thermal

overload.

FUNCTIONALITY

35

There are two thermal models supported by MC510: Standard or EEx e. The standard model

makes use of parameters Trip class, t6 in thermal overload calculation. The protection of

explosion proof three-phase motors with type of protection ‘increased safety’ EEx e is done with

two special parameters, the Ia/In ratio (stall/nominal current ratio) and Te time.

The following diagram offers the characteristic curve of overload protection, in which the

characteristics are adjusted by changing t6 (trip t

state).

If EEx e thermal overload protection is required, please contact ABB for detailed

clarification.

Fig 23 Trip curve from cold condition

The Maximum thermal capacity level is 100%. Maximum level is reached when motor has been

running with a current 6xIn at the time t6 starting from the cold state in ambient temp. 40°C.

FUNCTIONALITY

Table 23 IEC 60947-4-1 trip class when ambient temp. 40°C, balanced motor curren

If motor is in overload condition, i.e. ILmax > 1.14 x TFLC (Thermal full load current multiplier

reduced by motor ambient temperature), the Overload alarm is active to indicate overload.

In some applications it is beneficial to be able to bypass the TOL protection momentarily because

of the process reasons. The lifetime of the motor will be shortened but it might be more costly to

stop the process.

MC510 provides the function of TOL bypass protection. If the TOL bypass is triggered:

That is, when the motor is running, the thermal capacity value is allowed to reach 200% before a

trip occur.

Or when the motor has been tripped due to thermal overload protection, the motor is required to

start urgently when the heat capacity is below 200%.

TOL bypass protection may cause overheating and even fire. This function can be used

only if the customer is clear about the load, even if the motor is required to operate

under overload conditions. Otherwise, it may cause equipment damage, serious injuries

or even death.

Stall Protection

Stall protection is used to protect the driven mechanical system from jams and excessive

overload. Stall protection function uses Imax as the criterion.

Fig 24 Stall protection

More detailed information on stall protection parameter, please refer to Chapter Parameter

description.

Stall function activates after motor nominal startup time has elapsed.

FUNCTIONALITY

The highest measured phase current (ILmax) is compared against the Trip level. When ILmax remains

over the trip level at a time longer than Trip delay, a “Stall” alarm is issued and the contactor

tripped.

Long Start protection

The long start protection protects motor against locked or stalled rotor in starting state. MC510

detects the current after a start command, and signals a fault when current continuously exceeds

a separately set threshold of the period of start time.

This protection function is active only during the parameterized motor startup time. If motor startup

time has elapsed and will cause relay activation in case of a motor stall, but not long start protection.

Long start protection function is based on the highest measured phase current.

More detailed information on long start parameter, please refer to Chapter Parameter

description.

Long Start protection activates during motor nominal startup time and disables automatically

after predefined startup time.

The highest measured phase current (ILmax) is compared against the Locked rotor level. When ILmax

remains over the trip level at a time longer than Locked Rotor delay, a “Long Start” alarm is issued

and the contactor tripped.

(the ratio of highest measured phase value ILmax and the rated current of the motor In) as the criterion.

There are other parameters to be determined, such as alarm level, trip level and trip delay. The

protection characteristic is as follows:

There are two ways of earth fault protection in MC510 protects the motor against the earth fault

condition.

Direct measurement of zero sequence current through an external RCT

Calculation of zero sequence current by internal calculation through measurement current values

The function is by default suppressed by parameters “Motor startup time” and “Softstarter ramp up

time” to avoid nuisance tripping due to harmonics caused by saturation of the current transformers.

In some cases, it may be required to be switched on during startup in specific project requirements.

This protection is neither intended to be used for pre-emptive isolation supervision nor for

personnel protection against electrical shock. For these applications ABB recommends the

usage of external protection devices (PRCDs / RCDs).

level a “Under power alarm” alarm is issued.

The power factor is compared against the trip level. When it remains below the Trip level at a time

longer than Trip delay, a “Under power trip” alarm is issued and the contactor tripped.

Phase sequence protection

MC510 protects the motor against wrong phase sequence condition. The protection bases on the

sequence of voltage input while motor is stopped. And while motor is started, it bases on the

sequence of current. The predefined phase sequence as following,

Voltage: VL1,VL2, VL3

Current: IL1, IL2, IL3

While the protection is enabled, there will be a trip while the measured phase sequence is different

from the predefined sequence.

The function is by default suppressed by parameters “Motor startup time” and “Softstarter ramp up

time” to avoid nuisance tripping due to harmonics caused by saturation of the current transformers.

In some cases, it may be required to be switched on during startup in specific project requirements.

FUNCTIONALITY

45

More detailed information on phase sequence protection parameter, please refer to Chapter


Start limitation

Start limitation helps to protect the motor and also the process against excess number of starts in a

given interval. When the number of starts is reached and the motor is switched off, a new start is

prevented. The time interval starts from the first start. After the elapse of the time interval the

counter is reset to the pre-set value. The permissible motor starts per hour can be obtained from the

manufacturers motor and apparatus data sheet. However, the minimum waiting time between two

starts shall be complied.

The parameterization of the protection function can be the number of starts per time interval or the

time between two consecutive starts. In the first case the user must wait after the trip for the reset to

take place before making a start.

Independent of this function, the motor is protected by TOL function and a start is possible only if the

thermal capacity is below the startup inhibit level. If motor data specifies the number of starts during

a certain time span the advantage of this protection function can be taken of supervising the number

of starts. On some other cases process may put requirements for the motor start number thus this

protection can be employed.

Functionality is presented in the following example. Fig. 36 presents the start limitation protection

with 3 starts allowed.

1) Normal situation, after stop command motor can be started normally, “Start 2”. Every start

activates an internal timer for the time defined by time interval parameter. The number of active

timers are reviewed after every stop command and compared to value of number of starts parameter.

Stop command can thus exist during active or elapsed timer.

2) Two timers are still active, thus stop command generates alarm message "Start limitation alarm"

and one more start “Start 3” is allowed.

3) The 3rd start has been executed. A contactor trip and trip message "Start Limitation Trip" alarm will

follow when motor is stopped while there are two active timers, here starting from “Start 1”.

4) Trip can be automatically reset when the first timer from “Start 1” is finished. Motor start is

possible when all pending trips are reset. Supervision continues with a new timer from “Start 4”

Loop environment Temperature protection

MC510 extends the module hotspots module MT561 to monitor the ambient temperature inside the

drawer and prevent the drawer components from being too high, thus causing the drawer to burn

down. MC510 monitors the temperature of drawer environment to decide whether to trigger

environmental temperature protection alarm.

For details, please refer to the hotspots module MT561 section of the extended module user guide.

When MT561 is only used for loop environment temperature protection, there is no need to

configure hotspots temperature sensor.

Hotspots temperature protection

By extending the module hotspots module MT561, MC510 monitors the temperature of the inserting in

the drawer to prevent the temperature of the drawer from being too high, which leads to the burnout

of the drawer.

The single insertion temperature measurement is realized by inserting a fixed temperature infrared

sensor IR. MC510 monitors the temperature of one primary connector to decide whether to trigger a

temperature protection.

FUNCTIONALITY

Busbar temperature protection

MC510 monitors the copper temperature in the switchgear by extending the module MT564 to

monitor the copper temperature in the switchgear, including the main busbar, the copper platoon of

the ACB cabinet, and the copper row of the fixed circuit.

The bus temperature measurement is realized by self-powered wireless temperature measurement

module WT01, and transmitted to MT564 through Zigbee. MC510 monitors the temperature of the bus

bar to decide whether or not to trigger the bus temperature protection.

Thermal protection of motor (PTC/PT100/PT1000)

The thermal protection of the motor is used as a protective condition to determine the protection

function of the PTC/PT100/PT1000 thermistor detector, which is pre buried on the stator winding or

bearing of the motor.

MC510 realizes motor thermal protection through analog input and output module MA552. MC510

according to the measured resistance value, decide whether to turn on the corresponding motor

thermal protection.

For details, please refer to the MA552 section of the analog input and output module in the extended

module user guide.

Analog input signal monitoring function

MC510 monitors the input of analog input in analog input and output module MA552 in real time, and

sends out corresponding signal according to the preset alarm level value and trip level value.

For details, please refer to the MA552 section of the analog input and output module in the extended

module user guide.

Autorestart Function

The line voltage (UL1L3) is supervised continuously. It is possible to automatically restart the motor

after momentary power loss. Two alternative models of auto restart function are provided in MC510:

Standard and enhanced.

More detailed information on autorestart function parameter, please refer to Chapter Parameter

description.

When any DI is set to "main switch state" and the main switch state is not input, the

automatic restart function will automatically fail.

FUNCTIONALITY

49

Autorestart function (standard)

In standard mode, the reaction of the auto restart function depends on the length of the voltage dip.

The following cases show the different reactions of MC510 in different voltage dip situations.

Case 1: Voltage dip< autoreclose time

Fig 40 Autorestart (Voltage dip< autoreclose time)

If voltage is restored within the autoreclose time, the motor will be restarted immediately.

Case 2: autoreclose time<voltage dip< Max. power down time

Fig 41 Autorestart (autoreclose time<voltage dip< Max. power down time)

If power is restored after autoreclose time but before max power down time, motor will be restarted

after the staggered start delay time.

FUNCTIONALITY

50

Case 3: Voltage dip> Max. power down time

Fig 42 Restart (Voltage dip> Max. power down time)

If supply voltage remains below restore level long enough and exceeds max power down time, no

automatic restart will be initiated.

Autorestart function (enhanced)

If the voltage dip is taken more serious, the enhanced autorestart function can be applied.

In the enhanced mode, the reaction of the auto restart function not only depends on the length of the

voltage dip, but also the number of voltage dips within short period of time.

The following cases show the different reactions of MC510 in different voltage dip situations.

Case1: Voltage dip< autoreclose time

Identical to Case1 of standard mode

Case2: autoreclose time<voltage dip< Max. power down time

Modbus TCP Failsafe Functionality

MC510 failsafe function supervises the network interface and connection to the remote devices

controlling the motor/starter equipment by MC510. Remote device have to refresh the certain MC510

network input variable to indicate that the control is operating normally and the network interface is

in good condition.

If a loss of Modbus/TCP communications for preset timeout value (1-25 seconds) is detected, the

failsafe activates with the parameterized function as follows:

• No operation

• Start motor direction 1


• Stop motor

When communication failure is detected and activated by MOSBUS TCP failsafe mode, MC510 will

automatically release remote control permissions (if remote control authority has been selected).

IO BUS Failsafe Functionality

MC510 failsafe function supervises the network interface and connection to the extension modules by

MC510. Remote device have to refresh the certain MC510 network input variable to indicate that the

control is operating normally and the network interface is in good condition.

If a loss of IO BUS communications for 200ms is detected, the failsafe activates with the

parameterized function as follows:

MC510 Control Authority

Control Authority

MC510 Control Authority is the term describing the privileges on allowing motor control operation

through MC510. It is also a setting parameter in MC510 to define which control access group has

privilege to operate the motor via MC510.

FUNCTIONALITY

53

Control Access

There are three control access groups defined in MC510,

Local Hardwiring: MC510 accepts its commands from the hardwired inputs

Remote Fieldbus: MC510 accepts its commands from PLC or higher control system via fieldbus, i.e.

MODBUS/TCP.

MP Control: MC510 accepts its commands from operator panel MP5x which locates on the front panel

of each starter unit on switchgear.

CHMI Control: MC510 accepts its commands from CHMI (MV570).

Assign Control Authority

There are several means in MC510 to assign control authority and decide which control access group

has the privilege to control.

Local/Remote control authority assignment

Parameter Setting:

Select the access group from parameter setting window (Fig 44). This is the most direct option where

control access is defined by parameterization software.

Fig 44 Parameter Setting of Local/Remote of Control Authority

Multi control access group is supported!

For MC510, only when no DI is assigned Loc/R, Soft Local/Remote could be selected.

FUNCTIONALITY

54

Local/Remote Selector Switch

MC510 supports hardwired local remote selector switch function which allows selecting control access

groups via hardwired inputs. To enable this function, one of the digital inputs has to be defined as

‘Loc/R’ in MC510 (Fig45).

Fig 45 Assign “Local/Remote” function to Digital Input

Local/Remote Selector Switch will then define if control access goes to “Local “(Local Hardwired) or

“Remote” (Remote Fieldbus). This function does not include the selection of operator panel MP control

which is independent of either “Local” or “Remote” and has to be further defined in this case.

“parameter setting” in parameterization software or through hardwired input.

FUNCTIONALITY

55

Parameter Setting

Fig 46 MP Control

Select the access group from parameter setting window (Fig 46). This is the most direct option where

control access is defined by parameterization software.

Hardwired Input

Use external selector switch to select MP control. Same as in Local/Remote Selector Switch function,

one of the digital inputs has to be defined as ‘MP Control” to enable the function.

Fig 47 Set DI as “MP Control”

When “MP control” is enabled in one of the DIs, the MP control access option will be gray out.

In another word, Hardwired Selection has privilege over Soft in terms of assigning control

authority.

FUNCTIONALITY

56

CHMI control authority assignment

The choice of CHMI control permissions is completely independent of local / remote selection. MC510

provides 2 ways to define control permissions for CHMI human-machine interface, such as parameter

setting through software or input signals through hard wire switches.

Parameter Setting

Fig 47-1 CHMI Control Authority

As shown in Fig 47-1, this is the most direct way to set up CHMI control permissions in the local /

remote switch input state.

Hardwired Input

Use external selector switch to select CHMI control. Same as in Local/Remote Selector Switch function,

one of the digital inputs has to be defined as ‘CHMI Control” to enable the function.

Fig 47-2 Set DI as “CHMI Control”

When “CHMI control” is enabled in one of the DIs, the CHMI control access option will be gray

out. In another word, Hardwired Selection has privilege over Soft in terms of assigning

control authority.

FUNCTIONALITY

57

Main switch protection function

The main switch protection function is based on the protection function of MNS drawer handle

operation. This function monitors the state of the main switch under different motor circuits and

enhances the functional safety of the MNS system.

If you want to turn on the protection, you need to connect the main switch status and the test

position status to the DI of MC510. In this case, the action performance of MC510 is as follows:

Stop Normal Normal Normal Normal Normal Main switch trip

When MC510 monitors the test position, the "T" will appear on the top right corner of the

MP51 LCD.

The main switch state can be individually connected to MC510 without the need to access the test

position. In this case, MC510 only monitors the state of the DI, and the performance of MC510 is as

follows:

Motor Status Main Switch State

CloseOpen OpenClose

Running（Current feedback） Main Switch trip --

Running（contactor feedback） Main Switch trip --

Stop Normal Normal

The test position state can be accessed to MC510 individually without requiring access to the main

switch state. In this case, MC510 monitors the main switch in real time. When the main switch is in the

test position, MC510 monitors the three-phase current and the "I/O" point state, and allows the

contactor control loop to be controlled, but all protection functions based on current and voltage are

invalid. When the input of the switch is defined as the "test position", if the input point is the same as

the set state, the main switch is in the normal working position; on the contrary, the main switch is in

the test position. For example, if the contact type is normally closed, when the input is high, the main

switch is in the normal working position and the high level is cancelled. However, when the main

switch is in the test position but MC510 detects the current (>5% Ie), all the protection functions will

be automatically opened according to the set parameters, while ignoring the "test position". The

action performance of MC510 is as follows：

Maintenance Function

MC510 provides maintenance function for motor by supervising running hours, start numbers, trip

numbers and SOE.

When the maintenance parameter over the predefined alarm level, MC510 will trigger an alarm signal

accordingly. The operation of separate maintenance functions is independent thus these functions

can be active and given an alarm at the same time.

Motor running time

MC510 counts motors running hours. When running hours exceeds, MC510 will issue a “running time”

alarm.

Insertion cycles

MC510 gets the value of insertion cycles via counting control power cycles. When times of

Insertion cycles exceeds alarm level, MC510 issues an alarm.

MC510 also provides some other maintenance information of motor, which will convenience users to

get the report of motor.

Number of Trips

MC510 counts number of trips and updates in memory map.

Parameter change counters

MC510 counts times of parameter change and updates them in a memory map.

SOE

MC510 provides event recorder data for up to 256 events with time stamp.

Metering and Monitoring

MC510 provides an extensive range of motor operation supervisory functions. Supervisory data are

transmitted via MODBUS TCP to the upper level system for centralized management and also can

directly displayed on the operator panel MP51 if installed on the front of the motor starter module.

MODBUS/TCP

MODBUS/TCP is MODBUS over TCP/IP protocol. It is mainly used the monitoring and control of

automation.

MODBUS/TCP implemented in MC510 follows the specification below,

- Modbus application protocol V1.1b

- Modbus Messaging on TCP/IP Implementation Guide V1.0b

Refer to 1TNC928207M0201 for the MODBUS command supported by MC510.

MC510 supports 4 ODBUS/TCP master at the same time.

Modbus/TCP connection

Two-port Ethernet switches are integrated inside MC510. It makes system integration flexible and

econic. Three topologies are supported,

-Start

-Daisy chain

-Ring

Network characteristics

Designation Description

Type of cable Straight or crossed category 5 shielded twisted

pair

Maximum cable length between two adjacent devices 100 m

Maximum number of devices per network segment 160

Maximum number of devices per ring 50

Table 44 Network characteristics

The same network segment must have the same network identifier. For example, 192.168.1.x

is in the same network segment, while 192.168.1.x and 192.168.2.x are not in the same

network segment.

Topologies

Following figure illustrate the typical topology support by MC510.

Fig 53 Topology

Using ring topology in withdrawable cubicle

The drawers have the characteristics of low downtime. In the low voltage switchgear, the protection

and control equipment of a motor starter are all installed in the same drawer. When the circuit fails,

the user can replace the equipment quickly and conveniently to reduce maintenance hours. Moreover,

ring topology will ensure that replacing any one drawer will not affect the communication quality of

the whole system.

But if two drarwes are withdrawn, as shown in right part of fig 54, even if the system has MRP

redundancy function, the situation is totally different. Devices between these two drawers cannot be

accessed anymore.

Here MS571 should be used to ensure stable communication even if two or more drawers are

withdrawn, as shown in left part of fig 54.The MS571 is mounted in the cable compartment instead of

mounted inside the drawer. When draws are withdrawn, MS571 will bypass the withdrawn drawer

automatically to keep communication working in ring.

When the drawer withdraws, the network will spend less than 200ms to re-organize a new

network.

COMMUNICATION

67

Fig 54 Ring topology in withdrawable cubicle

No more than 5 consecutive drawers can be withdrawn in the same ring, otherwise, the

quality of communication will be affected.

Loop switch MS571

The loop switch is used for keeping the Ethernet loop healthy while the withdrawable module with

MC510 is removed. As shown in left part of fig 55, there are 4 RJ45 ports in MS571, 2 ports with MCU

mark are MCU interface to connect to MC510, 2 ports with BUS mark are BUS interface to connect in

Ethernet loop. The principle is shown as right part of fig 55, MC510 is introduced into the Ethernet

loop via MS571. When MC510 is removed, MC510 will be auto bypassed by MS571, so that the ring

Ethernet loop is still available.

COMMUNICATION

68

Fig 55 Loop switch MS571

The power supply of MS571 is provided from the BUS interface. As shown in fig 54, TA60

should be used for connecting the first and last MS571 to external device in one loop.

Directly connecting external device to “ETH BUS” port of MS571 may damage the device!

MS571 could not bypass MC510, when MC510 lose power.

TA60

Fig 56-1 TA60

The power supply of MS571 can be provided via TA60, there are 3 ports in TA60: RJ45 modular

plug, RJ45 modular jack, and two pair’s redundancy power cables. RJ45 modular plug is used to

connect to external device. RJ45 modular jack is used to connect to MS571 to provide power

supply and Ethernet loop signals. Two power cables should be connected to two redundancy

24VDC power supplies. The red core is 24VDC+ while the black core is 24VDC- for each power

cable. In case there is only one power supply, both power cables should be connected to this

power supply.

Fig 56-2 TA60 connection

Directly connecting external device to RJ45 modular jack of TA60 may damage the devices!

When the power supply is provided via TA60, the connection quantity is limited to maximum

50 MS571 modules, or maximum 4 MS572 modules. And the total cable length of power over

Ethernet should be less than 100 meter.

Description:

MC510 can handle a single or three phase AC motor. Based on the number of phases of the motor,

single or three can be selected. For single-phase motors, the motor current lead or the CT secondary

lead (for > 63 A) is passed through L1 phase window of the MC510 internal current transformer, and

the voltage input should be connected to VL1 and VL3.

Single Phase application is practicable with NR-DOL starter type. Neither the phase failure

protection, nor unbalance protection are supported in single phase application.

Motor Power Rating

Setting range without selecting external CT option is from 0.08-63A. In the case that external CT is

selected, the range is dependent on the primary and secondary of external CT, ie, If “External CT

secondary” is set to 1, the range varies from 0.5 to 1.0 of CT nominal primary current. If “External CT

secondary” is set to 5, the range varies from 0.25 to 1.0 of CT nominal primary current.

Example: In the case of an external current transformer Primary of 100A, the range varies from 50 to

100A when external CT secondary is selected as 1. The range can also be from 25-100A if secondary of

5A is selected.

Motor Control/ N2 parameters (NR-2N, NR_2N Dahlander)

Motor Control/ S/D parameters (NR-S/D)

Motor Control/ Autotransformer parameters

Motor Control/ Ramp Up/Down Time

Description:

MC510 supports different kinds of motor connections. This parameter need to be set according to

type of control desired for the motor.

More details of MC510 starter types is described in Chapter Function.

NR-DOL: Non Reversing Direct On Line.

NR - Non Reversing means that the motor only runs in one direction.

NR-DOL/RCU: Non Reversing Direct On Line RCU starter

RCU stands for Remote Control Unit. This is a starter type where contactors are allowed to be directly

hardwired controlled by control device located near the motor in parallel with MC510 control. In

another word, this starter allows motor being controlled by remote control device even if MC510 is not

in operation.

REV-DOL: Reversing Direct On Line.

REV- Reversing starter supports motor runs in both directions (clockwise CW, counter clockwise CCW).


91

REV-DOL/RCU: Reversing Direct On Line RCU starter

In addition to NR-DOL/RCU, this starter supports motor runs in both directions.

ACTUATOR: Actuator starter is for controlling valves, dampers, actuators by using limit switches.

NR-S/D: Reduced voltage starting in star and running of the motor in delta after meeting the

transition conditions.

Star-delta starters are used mainly to restrict the starting current of a motor due to supply limitations.

The motor is started with the winding connected in star and transferred to delta after the

"Changeover time". The starting at a lower voltage also reduces shocks on the motor coupling, belts

and the gear mechanisms. The starting current and the torque are reduced to 1/3 of the DOL value.

However, it must be determined whether the reduced motor torque is sufficient to accelerate the load

over the whole speed range.

NR-2N: Non-reversible two speed motor separate winding. Two speed drives are used for applications

requiring dual motor outputs. NR-2N is the starter designed for two separate winding motors.

Current measurement for NR-2N utilizes two sets of external CTs measuring current from main supply.

External CTs can be selected separately for both motor windings.

NR-2N Dahlander: Non-reversible two speed motor Dahlander connection

Two speed drives are used for applications requiring dual motor outputs. NR-2N Dahlander is the

starter type designed for motors with Dahlander connection.

Autotransformer: Non-reversible motor starter based on reduced voltage via auto-transformer.

Autotransformer starter supports motor starting with reduced voltage thus providing reduced motor

startup current. In a result, the starting torque is reduced accordingly.

NR_Softstarter : Non-reversible Softstarter Control

Softstarter applications are for controlling motor accessory softstarter device. MC510 gives start and

stop commands to the softstarter unit. The softstarter is set for adjusting motor voltage with its own

parameters. More information about softstarter can be found in softstarter manual.

Rev_Softstarter: Reversible Softstarter Control

Functionality of this starter type is according to NR-softstarter starter with support for reversing use

of motor.

Contactor Feeder: Feeder control by contactor.

When a “Start” command is given, the internal relay CCA remains closed until a stop command is given.

The internal relay CCB & CCC has no function here.


92

Contactor Feeder /RCU: Feeder control by contactor On Line (remote control of the contactor,

bypassing the MC510).

The “Start CW” command closes the internal relay CCA 1sec respectively. The stop command will close

relay CCC for 1 sec. The wiring of the self-auxiliary contact across the start command latches the

contactor.

Removing the MC510 from the starter will not prevent RCU operation depending however on the

connection (external relay and/or switch is used for start and stop). The stop pulse issued by the

MC510 will override the RCU-switch start position.

Modbus/TCP is one of the protocols employed in MC510. The devices with Modbus/TCP are named as

MC510-MT respectively and Ethernet is the only physical interface type provided. There are two

identical Ethernet interface arranged on each device to make the redundant design possible. Via

Ethernet interface all functions are supported, e.g. parameterization, control, supervisions, etc.

More information of Modbus/TCP communication, please refer to MC510 Modbus/TCP Protocol

Implementation.

Modbus/TCP communication protocol is used between MC510 and other devices, such as PLC or high

Ethernet Setting

Following section describes the Ethernet configuration parameters, MC510 supported Ethernet

services.

Simple Network Management Protocol

In typical uses of SNMP one or more administrative devices, called managers, have the task of

monitoring or managing a group of hosts or devices on a network. Each managed system executes, at

all times, a software component called an agent which reports information via SNMP to the manager.

SNMP agents expose management data on the managed system as variables. The protocol also

permits active management tasks, such as modifying and applying a new configuration through

remote modification of these variables. The variables accessible via SNMP are organized in hierarchies.

These hierarchies, and other metadata (such as type and description of the variables), are described

by Management Information Bases (MIBs).

An SNMP managed network consists of three key components:

•Managed device

•Agent: software which runs on managed devices

•Network management station (NMS): software which runs on the managed

A managed device is a network node that implements an SNMP interface that allows unidirectional

(read-only) or bidirectional (read and write) access to node-specific information. Managed devices

exchange node-specific information with the NMSs.

An agent is a network-management software module that resides on a managed device. An agent has

local knowledge or management information and translates that information to or from an SNMP-

specific form.

A network management station (NMS) executes application that monitor and control managed

devices. NMSs provide the bulk of the processing and memory resources required for network

management. One or more MNSs may exist on any managed network.

SNMP supports the following types of messages between and manager and the agent:

•Get Request: A manager-to-agent request to retrieve the value of variable or list of variables. Desired

variables are specified in variables bindings (values are not used). Retrieval of the specified variables is

to be done as an atomic operation by the agent. A response with current values is returned.

•Set Request: A manager-to-agent request to change the value of a variable or list of variables.

Variables bindings are specified in the body of the request. Changes to all specified variables are to be

made as an atomic operation by the agent. A response with (current) new values for variables is

returned.

•Response: Returns variable bindings and acknowledgement from agent to manager. Error reporting

is provided by error-status and error-index fields

•Trap: Asynchronous notification from agent to manager. SNMP traps enable an agent to notify the

management station of significant events by way of unsolicited SNMP message.


101

Fault Device Replacement

The FDR service employs a central server to store both the IP addressing and the MC510 configuration

parameters. When a failed MC510 is replaced, the server automatically configures the replacement

MC510 with the same IP addressing and configuration parameters as the failed one.

Motor Grouping

In the case of conventional switchgear, the operator can start or stop a process by sequentially

starting or stopping of the motors. The required delay between the motors is introduced either

manually or with the help of a timer and serial interlocks. This would increase the operators’ time,

cabling and the initial cost of the starter.

With help of intelligent system, the operator could start or stop the process with a single group

command. The start and stop delay can be set for individual motors. The serial communication with

logical connections between devices reduces the cabling, process interlocks and the hardware. In case

of abnormality in any motor of the group, a group tripping would follow.

In this context, a motor group means a collection of motors, which are operated by an individual

group start or stop command. The successful start of the motor group is indicated.

Individual start/stop command from fieldbus can also be given to the devices located in the

group as well as via the switches connected to the device I/O in the local mode.

The local control authority should be opened beforehand before use.

This function is used for hard wiring starting motor. After receiving the starting 1 instructions, the

motor will be running or running at low speed. After receiving the 2 instructions, the motor will reverse

or run at high speed. The function is an edge trigger mode.

Trip reset

The local reset authority should be opened before use. This function is used to reset the tripping

signal for the edge triggered mode.

Parameters involved in Function Type 1 are as below:

Description:

This value determine when MC510 takes the Operation after detected the input signal. If this value is

not 0, the MC510 will wait an Operation delay time then to take the Operation. If this value is 0, the

MC510 will take the Operation as soon as the input signal is detected.

Function Type 2

PLC control1/2

When the function is set to "PLC control 1" or "PLC control 2", and when the action signal is monitored,

the motor will continue to run in one direction or at a given speed until the opposite stop signal is

received.

"PLC control 1" allows the motor to rotate or run at low speed.

"PLC control 2" allows the motor to reverse or run at high speed.

If you want to turn on the PLC control function, you need to set the control authority to local hard

wiring.

TOL Bypass

If the thermal overload bypass function is selected and the signal input function block is detected by

MC510, the thermal overload bypass instruction of the motor is issued.

When the TOL bypass function is activated, MC510 allows the thermal capacity trip level to rise to

200% temporarily, that is, the motor can run continuously when the heat capacity is less than 200%,

and does not trip the motor, or allows the motor to start immediately when the heat capacity is less

than 200%.

If the TOL bypass function is to be activated, TOL bypass function must be enabled at TOL protection

window in MCUSetup, and then TOL bypass signal should be given to TOL bypass function block or

from fieldbus. The signal is a level detection mode.

TOL bypass function increases the thermal capacity trip level value, which may cause the

equipment to overheat or even burn down.

Protection Bypass

If the protection bypass function is selected, MC510 will detect the signal input function block and

issue the protection bypass instruction. At this time:

Motor is running. When MC510 detects the protection bypass signal input, all protection functions

that allow the protection bypass are switched to alarm only mode automatically. When the protection

bypass signal disappears, all the protection functions that allow the protection bypass are restored.

Protection with protection bypass is during trip delay time. When MC510 detects the protection

bypass signal input, the delay calculation will stop immediately. When the protection bypass signal is

lost, the delay calculation will restart if trip signal is still available.


121

The motor is tripped, but the trip is not cleared. When MC510 detects the protection bypass signal

input, the trip will be reset immediately. When the protection bypass signal disappears, the trip

information is redisplayed if the judgment condition of the trip is still available.

After the bypass is protected, the motor may run under dangerous conditions. Please be

careful when using it.

Function Type 3

Limit1/2

This function is used to install the limit switch. When the function is activated, the motor stops, and

the motor can only reverse control. That is, the limit switch 1, which limits the positive or low speed

operation of the motor, and the limit switch 2, which limits the motor reversing or the high speed

operation of the motor. The function is a level trigger mode.


122

Torque switch

When the function is set to torque switch, when the input signal is opposite to the setting state,

MC510 will release all control relays to stop the motor. This function is a level trigger mode.

External trip

This function is used to define the external tripping signal, which will cause the motor to trip. When

the signal is effective, the motor is tripped and needs to wait until the signal is lost before it can be

restarted. The signal is a level detection mode.

When the input point does not detect the external tripping input signal, MC510 will reset

automatically.

MP Control

This function is used to decide whether the operation panel can control the motor. When the function

is set to "MP control", the control authority of MP can’t be changed by parameter settings, and is

determined by the state of the input signal of the function. If the input signal is effective, the

operation panel MP can control the motor and vice versa. The signal is a level detection mode.

CHMI Control

This function is used to decide whether CHMI can control the motor. When the function is set to "CHMI

control", the control authority of CHMI can’t be changed by the parameter settings, and is determined

by the state of the input signal of the function. If the input signal is effective, CHMI can control the

motor and vice versa. The signal is a level detection mode.

Loc/R

This function is used for local / remote state control.

For MC510, if the local / remote input function is valid, the control permissions are local hard wiring; if

the signal is invalid, it is a remote bus. The signal is a level detection mode.

Test switch

This function is used to monitor whether the main switch is in the test position. If the main switch is in

the test position, MC510 monitors the three-phase voltage and the various "I/O" point states. MC510

can control contactors, but all protection functions based on current and voltage are automatically

closed, and only the control loop is tested.

When the current value of the monitor is not 0, all protection functions set by the parameter will

automatically turn on. This function protects the motor in the case of contact failure.

The contact is a level trigger mode.

Opening the "test position" function will trigger the monitoring function of the main switch to turn on.

The function of the main switch can be seen in detail as the main switch protection function in

Chapter Functionality.


123

Main switch status

When the function is set to "main switch state", the monitoring and protection functions of the main

switch will be switched on immediately. The input is the level detection mode.

F_Ca/F_Cb/F_Cc

Extension Modules

Extension modules are separate modules which support special functions such as digital input and

output, analog input and output. Extension modules are mounted beside MC510 basic module and

exchanges information via a serial communication interface called IO bus. The MC510 range of

products supports following modules:

1) DIDO, module which provides Digital Input Digital Output interface

2) AIAO, module which provides Analog Input Analog Output interface

3) Hotspots measurement, module which provides Infrared Temperature sensor to measure the

contacts/bus-bar temperature.

4) WTM, module which provides function to measure the bus-bar temperature and transfers data to

basic module via radio.

5) RCM, module which provides function to measure the residual current and over current protection.

For details, please refer to Extension module user guide.

Thermal Overload Protection (TOL)

MC510 protects the motor by calculating the thermal image of the motor both during running and

stop. This image is used to allow optimal performance of the motor with calculated time to trip.

The thermal image is calculated based on the highest of the three measured phase currents and

depends on the parameterized data such as trip class (t6), motor ambient temperature (TAMB), cool

down time factor (Mt6)

Motor ambient temperature is taken into account for thermal image calculation by means of a device

internal parameter TFLC. Where, TFLC is the highest of the measured three phase currents related to

motor ambient temperature.

When the thermal capacity level reaches the setting of trip level (e.g.100%), the thermal overload trip

will occur. The TOL trip can be reset after the thermal image goes below the motor reset level. The

motor can be restarted only after TOL trip is reset.

When the motor is being stopped, the thermal image calculation continues by using the background

heat level and cooling down time factor until thermal capacity level decreases to zero. The thermal

capacity decreases at a constant rate till it reaches the background heat level, after which it depends

on the parameters trip class, and cool down time factor. Thus, simulating cooling down of the stator

winding and the iron body of the motor.

During power failure, the thermal capacity level of the motor is stored in the memory and the cooling

down calculation starts from this level after resumption of power.

TOL Protection conforms to IEC 947-4-1, i.e with a motor current 1.05xTFLC running for 2 hrs will not

cause TOL-trip and subsequent rise in current to 1.2xTFLC will cause trip within 2 hrs.

In case of unbalance situation, the fictitious negative sequence current in remaining phases is taken

into TOL calculation to trip early.

Default Setting:Standard

Related Parameters:TOL protection / Parameters

PTC protection / Trip Level, Reset Level

TOL Protection/ Motor Ambient Temperature

Description:

The thermal model can be selected as either standard or EEx e. The standard model makes use of trip

class, startup I ratio and motor startup time in TOL calculation. Parameter trip class definition defines

the trip time for 6x motor nominal current (In) and it must be less than defined cold state maximum

value for the motor.

The protection of explosion proof three-phase induction motors with type of protection ‘increased

safety’ EEx e is done with two special parameters, the stall/nominal current ratio (Ia/In ratio) and te

time. The tripping time of the TOL protection from the cold state motor must be less than the te time

rated for the motor.

For EEx e thermal model a set of parameters have fixed values or are not available in order to simplify

parametering instructions and parametering process while providing a secured protection

functionality. This should be carefully considered by the user since the given parameter value do not

have effect to functionality in this case.

These are following parameters are not available when EEx e mode is selected:

Trip Class (T6)

Range: 3 (1) 40 s

Default Setting: 6s

Related Parameters: TOL Protection / Thermal Model (standard)

Motor Information / Nominal Current (In)

Motor information / Motor Ambient Temperature

Description:

Parameter trip class (t6) is the basic setting of the thermal protection function. For user it provides

the possibility to set the thermal model characteristic according to motor startup requirements and

characteristic. With trip class parameter user defines the time that protection allows current of 6x In

from cold condition for protected motor.

Motor start-up is the most common occurrence of the short overload situations. Normally two starts

from cold condition and one start from a hot condition are permitted. The Trip class (t6) value can be

set according to one cold start, which allows easy setting of protection.

The Trip class (t6) time for protection is defined based on the motor maximum start time, which is

informed by the manufacturer.

Initial information required for Trip class (t6) definition.

– Motor startup current ratio (rated motor data, Is/In), see parameter Startup I ratio

– Maximum start time permitted for cold motor

– Maximum start time permitted for warm motor

– Motor ambient temperature, see parameter Motor ambient temperature.

Example 1. A thermal protection is set for a motor M2BA315SMC, 110 kW.

– Motor startup current ratio (Is/In) 7,5

– Maximum start time for cold motor 30 s

– Maximum start time for warm motor 15 s

– Motor ambient temperature 40°C

With the initial information the protection characteristic can be defined by the following procedure.

First, the motor start current is calculated according to the ambient temperature. Practically, with

40°C of ambient temperature, the following calculation for start current can be passed. For more

information of ambient temperature coefficient see table of maximum permitted current in chapter

“Ambient Temperature”.

Temperature coefficient is derived with the following routine. Since the motor ambient temperature in

the example is 40°C, the TFLC is 1.00 x In.

Motor startup current ratio is 7.5, thus motor rated start current (Is) is:

In

InIsIs

The effect of ambient temperature is derived, when Is and TFLC are known:

The calculated start current ratio (7.5) and motor maximum start time (30 second) are placed on the

cold condition time/current characteristic diagram. Start current ratio is located on the horizontal


133

axis, while the maximum permitted time for cold motor start is set on the vertical axis. The cross point

of these constraints shows the maximum setting for Trip class (t6).

The received setting is the absolute maximum value without further considerations and a lower value

can be selected. A longer start is not protected by thermal protection and additional protection

against stalled rotor is necessary. In case of thermal protection trip at start, with the setting of

maximum Trip class (t6) value, it is recommended to check the motor size for extreme start

requirement.

Now, the setting of 40 second is limited by the range of parameter. Value for Trip class (t6) is derived

from the cold condition time/current diagram, see the picture. This setting allows start time up to

approx. 26 second for cold motor, before a thermal protection trip occurs. The start time for a warm

motor, with this parameter setting, can be read from the hot condition time/current diagram

accordingly. The check routine is shown in the latter picture.

The warm condition start must be within motor ratings. In this case, the start time for a warm motor

is approximated from the latter picture and must be shorter than 12 second, as read from the picture.

In practice, start lasting longer than 12 second, will lead to trip from the thermal protection.

Diagram presented in 40°C Motor ambient temperature


134

Figure 13 Start time vs. Trip class (t6) definition from hot condition time/current diagram

Diagram presented in 40°C Motor ambient temperature

More optimized setting of the thermal protection is needed in case of one start for warm motor is

required. In this case the Trip class (t6) parameter is derived from the warm condition time/current

diagram according to actual duration of motor start and motor startup current.

The derived Trip class (t6) value is verified from the cold condition time/current diagram to ensure

that thermal protection trip time is less than maximum allowed start time for a cold motor, i.e. the

protection is well defined.

There is a need to arrange a separate protection for unsuccessful start, i.e. stalled rotor, if the thermal

protection characteristic allows longer start before trip than is allowed for the motor. Then stall

protection is utilized for a cold motor start supervision. By defining the operation of Startup time and

stall protection Trip delay the trip must be set before motor maximum start time is exceeded, in case

of unsuccessful start.

Motor information / Motor ambient temperature

Description:

The safe locked rotor time te of a particular induction motor is the time necessary for the winding

temperature to rise from its final operational value to a fixed maximum value determined by the

corresponding temperature class of the motor during locked rotor. It is of particular significance when

the overload protection is specified for motors destined for use in hazardous locations. The te time is

for EEx e motors to withstand Ia/In current.

The parameter value for trip class te time is as rated for EEx e motor in the data book which

represents the maximum value. Parameterized value for trip class te time can be equal or less than

motor rated te time. For a faster trip value less than rated is selected.

With Ia/In ratio this parameter makes it possible for MC510 unit to calculate the trip time of the motor

according to the load. MC510 calculates the trip time for EEx e motor automatically, but the trip time

for a certain current for further investigation can be defined as presented in this chapter.

Trip time can be defined with the help of following cold condition time/current diagram. Diagram is

according to TOL standard model cold condition.

Initial information, as parametrized, is required.

Ia/In ratio for EEx e motor

te time for EEx e motor

When Ia/In ratio is placed on the current (Is/TFLC) axis and te time is placed on the time (t) axis, the

co-ordinate on which the lines drawn through these points cross each other is located on the t6 curve.

According to defined t6 curve trip time vs. motor current are available from cold condition

time/current diagram. The same t6 curve can be used for defining the trip time from a hot condition

time/current diagram, as well.

For example: Ia/In ratio for EEx e motor is 7 and parameter te time value is 7 seconds. By using the

following cold condition time/current diagram t6 curve can be found. When t6 curve is defined other

trip times vs motor current are available.

Motor ambient temperature is not observed because it does not have affect in TOL EEx e module

usage, thus Ia/In can directly be used (see parameter Ambient temperature).

The readout is t6 curve which is either existing in the diagram or is an estimation below the defined

point. In this case Trip class (t6) = 9 seconds is estimated from the example picture below and is

drawn to the diagram. Trip time for current 3xIn is estimated approx. 40 seconds.

Cooling Coe. (Mt6)

Range: 1 (1) 10

Default Setting:4


Description:

For an accurate thermal image of the motor, MC510 needs to know the characteristics of the motor to

be controlled. Different motors in different environments need different time periods to warm up and

to cool down. The cooling down period for a stopped motor is usually about four times longer than

the warm up period and it certainly differs within the motor, e.g. in certain hot spots of the windings

from the iron core. But this value can be different depending on dirt or other material covering the

motor, motor body size, weight installation place, etc.

The normal value for the parameter is between 4…8 describing the slower cooling for a stopped

motor [curve 1 and 2] than cooling of a running motor [curve 3]. In practise, this has been discovered

as the normal rule for motors covering various applications.

However, if motor manufacturer gives recommendation for another value, it may be set to the

protection.

For example: External cooling system is installed for improving the cooling down of a stopped motor.

Furthermore, according to statement from motor manufacturer cooling time constants for a running

and stopped motor are equal. Thus the parameter can be set below recommended value 4 [curve 1].

reaches the reset level.

Remote Reset: Reset through fieldbus. Reset is not possible before the calculated thermal capacity

reaches the reset level.

Local Reset: Reset the relay through local logic or MP panel. Reset is not possible before the calculated

thermal capacity reaches the reset level.

TOL Bypass Enable/Disable

Range:Enabled / Disabled


Related Parameters: TOL protection / Thermal model (standard)

Description:

The operation of the TOL protection function can be prevented by a special ‘TOL bypass’ command

given via the fieldbus/local logic. With the TOL bypass feature the thermal level can be raised up to

200 % after which a trip will be executed. The possibility for execution of this command is enabled by

this parameter.

An emergency restart is possible with the thermal capacity being above the startup inhibit level by

issuing a start command immediately after TOL-bypass command. TOL-bypass command cannot be

enabled when the EEx e parameter is active.

Active/Inactive TOL Bypass command is available from fieldbus/local logic.

Description:

Motors of basic design are intended for operation in a maximum ambient temperature of 40°C. If a

motor is to be operated in higher ambient temperature, it should normally be derated and should not


139

be loaded to the same thermal capacity. Normally this reduction of output power is done

automatically by MC510 but it is also possible to do it manually which is instructed later in this chapter.

To calculate the thermal image of the motor being protected, the MC510 needs to know the

temperature of the environment in which the motor is running. Especially in industries, where the

motors are located near the heat source, the maximum thermal capacity level of the motor is reduced

based on the increased surrounding temperature.

Motors designed for EEx e applications are always rated and certified for a certain maximum ambient

temperature, most commonly 40°C. If EEx e motor is designed for other temperature manufacturer

will supply the motor rated data.

Because of the nature of EEx e motor the output power ratings are not reduced automatically

according to ambient temperature by MC510. Instead of using ambient temperature parameter

MC510 uses fixed value 40°C, thus multiplier is one (1) when TOL EEx e model is selected.

The MC510 reduces the maximum permitted current by the multiplier as indicated in the table below

(TOL standard model).

Ambient temp. °C 40 45 50 55 60 65 70 75 80 Ambient temp. °C

= In x

1.00 0.96 0.92 0.87 0.82 0.74 0.65 0.58 0.50 Permitted

output, % of rated

output

For example: The thermal capacity level of the motor reduces from 100% at 40°C to 85% at 50°C.

Therefore, the motor can be loaded maximum to 92% of its rated load at 50°C.

Manual reduction may be needed if other reduction multiplier than presented in the table above are

required. Output power reduction is done by setting the value 40°C to parameter motor ambient

temperature and calculating the temperature reduction directly to nominal current. When multiplier is

calculated this way it must be applied to trip class time as well (Is/TFLC).

For example: Motor data sheet specifies that in 60°C motor can be loaded maximum of 75% of the

nominal. Thus motor ambient temperature is set to 40°C and when setting the nominal current the

rated motor current is derated,

xInrrentnominal cu 75.0

When nominal current is derated trip class parameter is defined with the same factor. It should also be

considered that other parameter’s, i.e. protection function trip and alarm levels, referring to nominal

current are effected relatively.

Stall Protection

Stall protection is used to protect the driven mechanical system from jams and excessive overloads.

Under such conditions, the motors have to be switched off in good time and reported to avoid undue

mechanical and thermal stress on the motor and the installation.

This protection function is active only after the motor has successfully started or after parameterized

motor startup time has elapsed and will cause relay activation in case of a motor stall while it is

running.

The parameter can be set to a higher value for application experiencing overload as part of normal

operation.

Large low-voltage motors and those devices (e.g. mixers, crushers, saw cutters, etc) having

short admissible stalling time less than the startup time are not protected by this function.

Phase failure in motor phase currents is a common phenomenon in industrial environment. It generally

occurs because of pitted contacts in the contactor or SCPD, imbalance in the mains supply, loose

connections, blown fuse, and faults within the motor. It is an extreme situation where a complete loss

of phase occurs. This can be caused by a utility supply problem or by a blown fuse in one phase.

Unbalanced phase currents are a major cause of motor thermal damage due to the nature of the

current. The negative sequence current induced in the rotor is of double the power supply frequency

and produces a counter torque to the desired motor output. For small unbalances, the overall output

torque will remain same as motor develops a large positive sequence torque to overcome the negative

sequence torque. This opposing torque and the high negative sequence current lead to an increased

temperature rise in the rotor and stator.

Reasons for the phase failure are neither temporary nor self-covering. Although TOL protection

performs an accelerated trip during phase failure and unbalance over 20%, there are no good reasons

to wait for the trip to occur through TOL protection. By the use of phase failure protection a motor

can be tripped without waiting for thermal calculation. Indeed, phase failure protection should be

parameterized to trip in shorter time than TOL does.

Underload protection function monitors the process against loss or decrease in motor load. This

protection function is current based protection. It is especially useful for indication of loss of suction

for pumps, broken belt for conveyors, loss of airflow for fans, broken tools for machines etc. Such

states do not harm the motor but early diagnosis helps to minimize the extent of damage to the

mechanical installation and subsequent loss of production.

The motors on underload draw mainly the magnetizing current and a small load current to overcome

frictional losses. Therefore, the other reason to isolate the motors on underload is to reduce the

reactive load on the power system network.

Protection” is based on the power factor of the motor. The reactive component of the current is fixed

during underload and the power factor reduces substantially along with the slight decrease of the

active current.

Earth Fault Protection

The earth fault protection function protects the motor and the network against Earth Fault Current

flow. During earth fault, the motors can reach a dangerous potential above the ground level thus

posing safety hazard to personnel. The earth faults are mainly caused due to ageing of the insulation,

deterioration of insulation due to sustained or cyclic overloading, moisture or conductive dust. Most

insulation faults result in leakage to the frame of the motor. Earth fault protection in MC510 device

provides the protection for fatal isolation damages.

Undervoltage Protection

The undervoltage protection function protects the motor against overload during voltage dips. During

a mains undervoltage, the electrical energy required to drive the rotor remains same for some period

owing to its inertia.

According to the energy conservation law,

Mechanical energy= Electrical energy

Where, VL is the motor line voltage, IL is the motor line current and Cosphi is the power factor.

From equation 1, the motor draws more current during voltage dips to deliver the same mechanical

energy.

The motors switched off during voltage dip or power failure can be restarted on power resumption

sequentially to prevent simultaneous switch-on of the motors and thus prevent another mains failure

on the network. The tripping of motors due to undervoltage of short duration can be bypassed. The

feature also would help to restart the process on power resumption by sequentially starting the

motors (staggered start).

The Undervoltage protection also prevents startup of the motor if the voltage is not high enough and

indicates phase loss before switching ON the motor.

Maintenance

Preventive maintenance is the best way to have long service life for any equipment. Maintenance

function can be configured suitably as a reminder for preventive maintenance. This would reap high

benefits to the user in terms of reduced process down time and loss due to stoppage of production.

Maintenance function indicates the operation of the motor in terms of hours run and the usage of

starter in the form of operating cycles. Number of hours run helps to assess the bearing life and its

lubrication or replacement, whereas the number of operating cycles help in deciding replacement of

worn-out power contacts or the contactor itself.

Maintenance alarm can be activated after lapse of the set counter. The counters can be set after

maintenance according to two different principles depending of course on normal routine of the user.

Running Time Alarm Level

Range:0 (1) 65,535 h

Default Setting:65535(Disabled)


Description:

The user can set a period after which a preventive maintenance is desired. When the Running timer

exceeds the preset running time alarm level, an alarm message ‘Running time’ is generated for the

corresponding MC510. This helps to lubricate and maintain the bearings of the motor within the

correct service interval.

When the parameter is set to 65535, the running time alarm is disabled.

Start Number Alarm Level

Range:0 (1) 65,535



Description:

This parameter reflects the control cycles of contactors. User can set this parameter in lines with the

electrical life of a contactor. When start counter has run through the set value of cycles in preset start

number alarm level, the corresponding MC510 generates an alarm message ‘Start number’. This help in

carrying out preventive maintenance of power contacts.

When the parameter is set to 65535, the start number alarm is disabled.

Insertion Cycles Alarm Level

Range:0 (1) 65,535



Description:


164

This parameter reflects the insertion cycles of drawer. When the Insertion cycles counter exceeds the

preset insertion cycles alarm level, an alarm message ‘Insertion cycles’ is generated for the

corresponding MC510.

When the parameter is set to 65535, the insertion cycles alarm is disabled.

User Definable Map

The MC510 contains a User Definable area in the memory map. This area allows re-mapping of the

addresses of any Actual Values or Setpoints registers. The User Definable area has two sections:

1. A Register Index area (memory map addresses 13D0H-141FH) that contains 80 Actual Values or

Parameter register addresses.

2. A Register area (memory map addresses 0100H-014FH) that contains the data at the addresses in

the Register Index.

Register data that is separated in the rest of the memory map may be re-mapped to adjacent register

addresses in the User Definable Registers area. This is accomplished by writing to register addresses

in the User Definable Register Index area. This allows for improved throughput of data and can

eliminate the need for multiple read command sequences. The User Definable Register Index is stored

as a parameter and therefore it is “remembered” even when the power is removed.

For example, if the values of phase L1 current (register address 0030H) and Motor Status (register

address 0019H) are required to be read from a MC510, their addresses may be re-mapped as follows:

Write 0030H to address 13D0H (User Definable Register Index 0000) using function code 06H or 10H.

Write 0019H to address 13D1H (User Definable Register Index 0001) using function code 06H or 10H.

It is now possible to read these two data registers with one read, at addresses 0100H, 0101H. Address

0100H will contain Phase L1 Current and address 0101H will contain Motor state.

MP LED

The MP (Operation Panel) has 4 LED indicators. All LEDs can be configured with various color and

function. As shown in Figure.32 and 33, from top to the bottom, the LED is called LED1, LED2, LED3 and

LED4.
