This manual should be studied carefully before installing, parameterizing or operating the motor control unit. It is expected that the user has a basic knowledge of physical and electrical fundamentals, electrical wiring practices and electrical components. This document should be used along with M101-P/M102-P Parameter Description, which provides detailed information about parameters and their applications. 1.2 Related Documentation 1TNC 9111106M0202 M101-P/M102-P Parameter Description M101-P/M102-P 1TNC 9111507M0202 PROFIBUS Protocol Implementation for M101-P/M102-P

2 Product Overview 2.1 Introduction M101-P/M102-P is a motor protection and control device with a fieldbus interface.

M101-P/M102-P is a microprocessor-based device. All motor protection and control functions are implemented with the microprocessor, as well as interlocking functions, the calculation of operating, diagnosis and statistical data and communication.

Standard features simplify maintenance and plant expansion. One M101-P/M102-P is required for every starter unit in the MCC. Motor protection is included for the most common causes of failure to prevent costly shutdowns and rewinds. These include overload, stalled rotor, ground fault and phase failure etc. M101-P/M102-P with Profibus interface makes it possible to network upward with automation level in a high speed and reliable way. The M101-P/M102-P implements a subset of the Profibus-DP communication standard. Any M101-P/M102-P may be interrogated on demand to determine both actual and operating parameters. Fast response time for alarm or trip status makes real time control of a complete process possible. Statistical recording of running hours and number of operations assists with predictive maintenance scheduling. Picture 1 M101-P/M102-P

For AC motor and the operated installation this means:

• Reliable protection • Maximum utilization • Continuous supervision • Flexibility

4.1.6 Voltage measurement (only for M102-P) M102-P continuously measures three phase voltages. The voltage data is used for protection functions and power calculation. Note: The M102-P has voltage input only. Table 8 Voltage input terminals of M102-P only. Terminal No. Name Description X3:9 Vc Phase C voltage input X3:11 Vb Phase B voltage input X3:13 Va Phase A voltage input X3:8 N Neutral line input 4.1.7 Current measurement terminal M101-P/M102-P measures continuously three motor phase currents. The phase current data will be used by the protection functions and is reported to the fieldbus. Phase currents are reported as relative value. Relative value is proportional to the motor nominal current In. Current wires are lead through current sensors from either side of the terminal. Direction can be either L->T or T->L considering that all currents must have the same direction. Motor nominal currents above 63A are not measured directly, but instead intermediate current transformer’s secondary side is connected through M101-P/M102-P current measurement terminal. Note: when one phase system is selected, current is measured only from phase A. 4.1.8 Contactor control output M101-P/M102-P supports several motor starter types. The control of the contactor is performed with internal relays (Output CCA, CCB, CCC) by the microprocessor. Internal relays CCA and CCB are hardwire-interlocked to prevent both contactors being closed at the same time. Note: M101-P has the relays CCA and CCB only.

5.2 Protection Function The module provides full protection for motor by supervising three phases voltage, three phases current, earth fault current, PTC sensor, the state of contactors and the state of main switch. Functionality 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 setup tool, also the protection characteristics can be adjusted. Protection module offers the following protection and supervisory function. Table 25 Protection supported by M101-P/M102-P

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. Picture 22 Principle picture of motor thermal simulation

M101-P/M102-P 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. There are two thermal models supported by M101-P/M102-P: 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 character is adjusted by changing t6( trip time for current ILmax=6×In from the cold state). Picture 23 Trip curve from cold condition

The Maximum thermal capacity level is 100%. Maximum level is reached when motor as been running with a current 6xIn at the time t6 starting from the cold state in ambient temp. 40°C.

10 7-12 20 10-25 30 15-38 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 will be more costly to stop the process. TOL-bypass is a special command given through the fieldbus. There is a dedicated parameter to enable the execution of this command. TOL-bypass function is available only for TOL standard model, thus it can not be enabled if TOL EEx e model is in use. When thermal level is above parameterised alarm level there is a possibility to send a bypass command to M101-P/M102-P. When bypass function is activated, the thermal image is allowed to rise to 200% level before a trip will occur. 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, but time to trip is not updated if the thermal capacity level (θ) is not going to rise above 200% (ITOL < √2). If motor is stopped before trip and the thermal capacity decreases below TOL alarm level the bypass functionality is disabled. Bypass command is ignored when running under alarm level.

The resistance of PTC input is compared against the Alarm level. When resistance of PTC input exceeds above the Alarm level, a “PTC alarm” message is issued. The resistance of the PTC input is compared against the Trip level. When resistance of PTC input is above the Trip level “PTC trip” alarm is issued and the contactor tripped. After PTC trip is executed the resistance of PTC input is compared against the PTC reset level. When resistance of PTC input decreases below the reset level, the PTC protection function executes the function parametrised by “PTC Reset Mode”. 5.2.9 Undervoltage protection (only for M102-P) M102-P protects the motor against undervoltage condition as “voltage dip”. The undervoltage protection function uses ULmin as the criterion. There are other parameters to be determined, such as alarm level, trip level and trip delay, reset voltage level. The protection characteristic is as follows: Picture 31 Undervoltage protection

The lowest measured main voltage (Ulmin) is compared against the undervoltage alarm level. When Ulmin decreases below the undervoltage alarm level, an “Undervoltage alarm” alarm is issued. The lowest measured main voltage (Ulmin) is compared against the undervoltage Trip level and voltage restore level. When ULmin recovers above undervoltage Restore level before Trip delay expires and motor continues running. If ULmin remains below the restore level at a time longer than Trip delay, “ Undervoltage trip “ is issued and contactor will be opened. Note! If Autorestart function is active, the autoreclose time is treated as the trip delay. The undervoltage trip delay is suppressed.

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 parameterisation 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. The time to reset after start limitation trip is provided to the fieldbus. 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. The next picture, 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 is allowed, “Start 3”. 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”. When start limitation trip is active the time to reset is provided to the fieldbus. 4. Trip can be 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”.

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 a certain time.

5.3.2 Number of Starts M101-P/M102-P counts number of start. For each operation cycle M101-P/M102-P updates the number of operating cycle in memory map. When start number alarm level is exceeded, M101-P/M102-P issues an alarm. 5.3.3 Motor running time M101-P/M102-P counts motors running hours. When the limit of running hours is reached, M101-P/M102-P will issue a “ running time” alarm. 5.3.4 M101-P/M102-P control authority 5.3.4.1 Terminology Motor control in this context means entering the normal motor control commands, such as motor start and stop, to the M101-P/M102-P. Functions such as internal or external tripping are not considered as normal motor control commands and are therefore left outside this definition. Motor can control by the digital inputs of the M101-P/M102-P (The function of DIs should be set as PLC control, Start1, Start2, Stop etc.). Control command comes from digital inputs (X1 terminals) called local control. Motor control can also be performed by other fieldbus network devices (DCS), which transit motor control commands to the M101-P/M102-P via fieldbus network. Control performed by other network devices via fieldbus can be called remote control. Operator panel (MD) or HMI(reserved) can be a option for motor control. 5.3.4.2 Local/Remote control switching Switching the motor control from remote to local and vice versa can be done by using the binary-I/O connected remote/local switch in the local control panel/switchgear control panel. This switch has the highest priority in the remote/local switching. If a digital input is assigned for the function of Loc/R, that means the Local/Remote function is enabled. The status of the Loc/R input will manipulate the control authority. 5.3.4.3 Control authority The control commands can be authorized by the Loc/R input and parameterization. When the function of Loc/R is assigned to a digital input in the parameters. The default control mode as follows.

Control Authority Loc/R input

Local Remote(Fieldbus) Operator panel MD HMI 0 (open input) Disabled Enabled Enabled Disabled(reserved)

1 (close input) Enabled Disabled Enabled Disabled(reserved)

When none of digital inputs is defined as Loc/R input, the function of Local/Remote is disabled, control commands can only be authorized via parameterisation. The default control mode as follows.

Control Authority Loc/R input

Local Remote(Fieldbus) Operator panel MD HMI

No Definition Disabled Disabled Enabled Disabled

Note: The blue-shaded fields can be set to either Enabled or Diabled via parameterisation, but for Profibus DPV0, it is only change the control authority via parameterisation kit. 5.3.5 Digital inputs There are thirteen separate programmable digital inputs( DIs) in M101-P/M102-P. These digital inputs can be assigned any of the functions listed below.

• NOP Not special operation for the digital input, only for the check of digital input status. • Start1 The input is used to control motor to start via hardwire. Motor can be running CW/N1 via Start1. • Start2 The input is used to control motor to start via hardwire. Motor can be running CCW/N2 via Start2. • Stop The input is used to control motor to stop via hardwire.

• Limit1 That is limit position switch1 input. • Limit2 That is limit position switch2 input. • Process interlock1 The process interlock1 function is used to provide time dependent trip/alarm/stop features based on a switch input. This function is used together with OPERATION DELAY and OPERATION parameters. The parameter of OPERATION DELAY sets the amount of time that the Process interlock1 switch can remain close on the occurrence of a motor start. If the switch remains unhealthy for longer than this time, a trip/stop will occur. If the parameter of OPERATION DELAY is set to 0, that the process interlock1 switch must be healthy for M101-P/M102-P to start the motor. OPERATION: this parameter determines whether process interlock1 feature is a trip( reset required in order to restart the motor), a stop (no reset required) or an alarm. Picture 37 Process Interlock1

Note: 1) When t1>t2, motor can run normally; when t1<t2, a trip or stop will be performed

according to the predefined operation. 2) When the operation delay is set to 0, if the process interlock1 is inactive, motor start will

not be allowed. 3) When Trip occurs, it can be reset only via MD2 or fieldbus.

• Process interlock2 The process interlock2 function is used to provide time dependent trip/alarm/stop features based on a switch input. This function is used together with OPERATION DELAY and OPERATION parameters. The parameter of OPERATION DELAY sets the amount of time that the process interlock2 switch can be remain open on the occurrence of a motor start. If the switch remains healthy for longer than this time, a trip/stop will occur. . If the parameter of OPERATION DELAY is set to 0, that the process interlock2 switch must be unhealthy for M101-P/M102-P to start the motor. OPERATION: this parameter determines whether process interlock feature is a trip( reset required in order to restart the motor), a stop (no reset required) or an alarm.

• Test switch input The input is used to indicate whether the main switch is in the test –position. While in test position, M101-P/M102-P monitors the I/O statuses and phase voltages/currents. Contactor operations by M101-P/M102-P are allowed but all protection functions based on the current and voltage measurement are disabled and the test of control circuit is allowed. • Emergency stop The input is used for the emergency stop device. When the input is active, the motor will be stopped and cannot restarted until the input is inactive. • PLC contact The input is used for the PLC contact input. When the PLC contact closes, the motor runs. When the contact opens, the motor stops. This input is only suitable for no-reversing starter. • Trip reset The input is used to reset a trip. • Reserved That is null. • Torque switch The input is used to check the status of torque switch used for Actuator Starter. When the input is different from normal state, M101-P/M102-P will release all contactor control relays to stop the motor. • F_CA That is contactor control A feedback. • F_CB That is contactor control B feedback. • F_CC That is contactor control C feedback. • Loc/R

5.3.6 Programmable output M101-P has one and M102-P has tow programmable relays output. These outputs can be assigned any of the functions listed below.

• Energize on motor start delay: Provides a delayed energization of relay when motor is started.

• De-energize on motor stop delay: Provides a delayed de-energization of relay when motor is stopped.

• Fieldbus control: The relay can be energized or de-energized via the fieldbus. • DI9 Status: The relay will be energized while the DI9 switch is closed • DI10 Status: The relay will be energized while the DI10 switch is closed • DI11 Status: The relay will be energized while the DI11 switch is closed • Trips: The relay is energized immediately after power on. and keep energized when no

trip. When a trip occurs, it will be de-energized. Then energized after trip reset. • Ground fault trip: The relay is energized immediately after power on when no ground

fault trip occurs. When ground fault trip occurs, it will be de-energized. Then energized after trip reset.

• Overload: The relay is energized immediately after power on when no overload trip occurs. When overload trip occurs, the relay will be de-energized. Resetting M101-P/M102-P will energize the relay.

• Watchdog output: M101-P/M102-P has an internal hardware watchdog supervising the behavior of the microprocessor software. Programmable output can be used as signaling output relay for indicating the status of the unit’s internal watchdog. In case of fault the watchdog activates and the relay is energized.

• Communication failure: The relay is energized immediately after power on when no communication failure occurs. When the failure occurs, the relay will be de-energized.

• RCU Mode (only for M101-P): This definition is assigned to the programmable out when ‘NR DOL/RCU ‘ or REV DOL/RCU is selected as motor starter mode. The relay output serves the same function of ‘ de-energized the contactor coil’ as ‘CCC’ output in M102.

• Local/ remote output (only for M102-P): The relay is energized when the control authority is Remote only .The relay will be de-energized when the control authority is Local and Remote or Local only.

PROFIBUS is multiple master/multiple slave type of protocol suitable for a multi drop configuration as provided by RS485 hardware. The M101-P/M102-P is always a PROFIBUS-DP slave. They could not be programmed as PROFIBUS-DP masters. Commonly computers or PLCs are acted as masters.

Note: For more detail information, please consult with Profibus organization or the manufacturer. 6.3 Profibus DP description PROFIBUS-DP is a distributed I/O system, which enables the master to use a large number of peripheral modules and field devices. The data transfer is mainly cyclic: the master reads the input information from the slaves and sends the output information back to the slaves. The services of the PROFIBUS Data Link Layer (Layer 2) are used by PROFIBUS-DP through Service Access Points (SAPs). Precisely defined functions are assigned to individual SAPs. For further information on Service Access Points, refer to the manual of the PROFIBUS master. The following SAPs are supported by the M101-P/M102-P:

SAP54 - Master-Master function SAP55 - Set or change address SAP56 - Read Input SAP57 - Read output SAP58 - Global Control Command SAP59 - Read Configuration data SAP60 - Read Diagnosis data SAP61 - Initial Parameters SAP62 - Check the configuration data SAP128 - User Data exchange

Note: More details on M101/M102 profibus pls refer to ‘ M101/M102 Profibus Implementation’.

7 Parameterization 7.1 Overview Parameterization means entering values to M101-P/M102-P parameters. Before integrated in a system, the parameters of communication should be set correctly only via the parameterization interface on operator panel. M101-P/M102-P parameters can be uploaded by and downloaded via the parametering device. 7.2 Parameterization via MD2/MD3 There is a USB-Pin physical interface on MD2 or MD3, which is for parameterization via a laptop. 7.3 Parameterization via PROFIBUS M101-P/M102-P parameters are listed in the PROFIBUS memory map. The user can parameterize M101-P/M102-P by using related SAPs. For detail information, refer to the PROFIBUS Protocol Implementation for M101-P/M102-P document. 7.4 M101-P/M102-P Parameters M101-P/M102-P Parameters are listed together with explanations, possible ranges and default values in the M101-P/M102-P Parameter Description document.
