Before commencing the installation

Disconnect the power supply of the device.

Ensure that devices cannot be accidentally restarted.

Verify isolation from the supply.

Earth and short circuit the device.

Cover or enclose any adjacent live components.

Follow the engineering instructions (AWA/IL) for thedevice concerned.

Only suitably qualified personnel in accordance withEN 50110-1/-2 (VDE 0105 Part 100) may work on thisdevice/system.

Before installation and before touching the device ensure that you are free of electrostatic charge.

The functional earth (FE, PES) must be connected to theprotective earth (PE) or the potential equalisation. Thesystem installer is responsible for implementing thisconnection.

Connecting cables and signal lines should be installed so that inductive or capacitive interference does not impair the automation functions.

Install automation devices and related operating elementsin such a way that they are well protected againstunintentional operation.

Suitable safety hardware and software measures shouldbe implemented for the I/O interface so that an opencircuit on the signal side does not result in undefinedstates in the automation devices.

Ensure a reliable electrical isolation of the extra-lowvoltage of the 24 V supply. Only use power supply unitscomplying with IEC 60364-4-41 (VDE 0100 Part 410) orHD384.4.41 S2.

Deviations of the mains voltage from the rated value mustnot exceed the tolerance limits given in the specifications,otherwise this may cause malfunction and dangerousoperation.

Emergency stop devices complying with IEC/EN 60204-1must be effective in all operating modes of the automationdevices. Unlatching the emergency-stop devices must notcause a restart.

Devices that are designed for mounting in housings orcontrol cabinets must only be operated and controlledafter they have been installed and with the housingclosed. Desktop or portable units must only be operatedand controlled in enclosed housings.

Measures should be taken to ensure the proper restart ofprograms interrupted after a voltage dip or failure. Thisshould not cause dangerous operating states even for ashort time. If necessary, emergency-stop devices shouldbe implemented.

Wherever faults in the automation system may causeinjury or material damage, external measures must be

implemented to ensure a safe operating state in the eventof a fault or malfunction (for example, by means ofseparate limit switches, mechanical interlocks etc.).

Depending on their degree of protection, frequencyinverters may contain live bright metal parts, moving orrotating components or hot surfaces during andimmediately after operation.

Removal of the required covers, improper installation orincorrect operation of motor or frequency inverter maycause the failure of the device and may lead to seriousinjury or damage.

The applicable national accident prevention and safetyregulations apply to all work carried on live frequencyinverters.

The electrical installation must be carried out inaccordance with the relevant regulations (e. g. withregard to cable cross sections, fuses, PE).

Transport, installation, commissioning and maintenancework must be carried out only by qualified personnel(IEC 60364, HD 384 and national occupational safetyregulations).

Installations containing frequency inverters must beprovided with additional monitoring and protectivedevices in accordance with the applicable safetyregulations. Modifications to the frequency invertersusing the operating software are permitted.

All covers and doors must be kept closed duringoperation.

To reduce the hazards for people or equipment, the usermust include in the machine design measures that restrict the consequences of a malfunction or failure of the drive(increased motor speed or sudden standstill of motor).These measures include:

Other independent devices for monitoring safety-related variables (speed, travel, end positions etc.).

Electrical or non-electrical system-wide measures(electrical or mechanical interlocks).

Never touch live parts or cable connections of thefrequency inverter after it has been disconnected from the power supply. Due to the charge in the capacitors, these parts may still be live after disconnection. Fitappropriate warning signs.

Selection criteria

Select RAMO or RASPc according to supply voltage ULN of thesupply systema and the rated operational current of the assignedmotorb . The motors circuit type (D or Y ) must be selectedaccording to the supply voltagea . The RASPs rated outputcurrent Ie must be greater than or equal to the rated motor current.For RAMO, current monitoring must be set to the rated motorcurrent.

When selecting the drive, the following criteria must be known:

Type of motor (three-phase asynchronous motor) Mains voltage = rated operating voltage of the motor

(e.g. 3 AC ~ 400 V), Rated motor current (recommended value, dependent on the

circuit type and the supply power supply) Load Torque, Starting torque, Ambient air temperature (rated value +40 C).

U, I, f

h When connecting multiple motors in parallel to the output

of the RAMO and RASP, the motor currents are addedgeometrically separated by effective and idle currentcomponents. When you select a RAMO and RASP, makesure that they can supply the total resulting current. Ifnecessary, for dampening and compensating the devi-ating current values, motor reactors or sinusoidal filtersmust be connected between RAMO or RASP and themotor.

For parallel operation of several motors on the output ofa RASP or RAMO separate motor protection (e.g. a therm-istor) is required.

h RASP onlyThe parallel connection of multiple motors in the outputof the RASP is only permitted with U/f-characteristiccontrol.

Speed control with slip compensation (P11.8) increasesthe drive dynamics and optimizes the output. With thisfunction the frequency inverter calculates an electronicimage of the motor.

In this operating mode only one motor can be operated onan output of the RASP. The motors rated current must beassigned to the rated operational current of the frequencyinverter (same rating).

All devices connected to the power and data bus must alsomeet the requirements for safe isolation according to IEC/EN 60947-1 Annex N or IEC/EN 60950. The 24 V DC powersupply unit must be earthed on the secondary side. The 30 V DCPSU for the AS-Interface power supply (interface control unit)must meet the safe isolation requirements according to SELV.

Emergency switching off devices (to IEC/EN 60204-1, corre-sponds to DIN VDE 0113, part 1) must be present. Their func-tion must not be impaired in any way.

Effective lightning protection measures must be implemented inthe plant to prevent damage to electronic components.

RAMO and RASP are not devices for household use, and aredesigned exclusively for use in commercial applications.

RAMO and RASP are electrical apparatus for controlling variable

speed drives with three-phase motors. They are designed forinstallation in machines or for use in combination with othercomponents within a machine or system.

After installation in a machine, the RAMO and RASP must not betaken into operation until the associated machine has beenconfirmed to comply with the safety requirements of MachinerySafety Directive (MSD) 89/392/EEC (meets the requirements ofEN 60204). The user of the equipment is responsible for ensuringthat the machine use complies with the relevant EU Directives.

The CE markings applied to RAMO and RASP confirm that, whenused in a typical drive configuration, the apparatus complies withthe European Low Voltage Directive (LVD) and the EMC Directives(Directive 73/23/EEC, as amended by 93/68/EEC and Directive 89/336/EEC, as amended by 93/68/EEC).

A connection to IT networks (networks without reference to earthpotential) is not permissible , since the devices built-in filtercapacitors connect the network with the earth potential (enclo-sure).

The technical data and connection conditions must be observed.For additional information, see the nameplate of RAMO or RASPand the documentation.

Any other usage constitutes improper use.

j Danger!Incorrect engineering, installation, maintenance andoperation of the entire plant or machine, non-observationof the instructions in this manual and modifications byinsufficiently qualified persons can cause danger fromconnected actuators such as motors, hydraulic units etc.

h Rapid Link is intended only for switching, protecting, andcontrolling three-phase motors in machines and plants. Anyother use is not proper use.

The vendor does not accept liability for damage resultingfrom use other than the stated proper use.

h At the output of RAMO and RASP (a section "Motorfeeder, page 45) you must not:

connect a voltage or capacitive loads (e.g. phasecompensation capacitors),

connect multiple RAMO and RASP in parallel, make a direct connection to the input (bypass).

Electrical power network

Mains connection and configurationThe Rapid Link modules RAMO and RASP can be connected andoperated with all control-point grounded AC power networks (seeIEC 60364 for more information in this regard).

The connection and operation of frequency inverters to asymmet-rically grounded TN networks (phase-grounded Delta network"Grounded Delta", USA) or non-grounded or high-resistancegrounded (over 30O ) IT networks is not permissible.

Mains voltage and frequency

The standardized rated operating voltages (IEC 60038, VDE017-1)for power suppliers (EVU) guarantee the following conditions at

the transition points: Deviation from the rated value of voltage:

maximum 10 % Deviation in voltage phase balance: maximum 3 % Deviation from rated value of the frequency:

maximum 4 %

The broad tolerance band of the RASP considers the rated value forEuropean as (EU: ULN = 230 V/400 V, 50 Hz) andAmerican as (USA: ULN = 240 V/480 V, 60 Hz) standard voltages:

400 V, 50 Hz (EU) and 480 V, 60 Hz (USA)

For the bottom voltage value, the permitted voltage drop of 4 %in the consumer circuits is also taken into account, therefore atotal of ULN - 14 %:

380 V -15 % - 480 V +10 % (323 V -0 % - 528 V +0 %)

The permitted frequency range in all voltage ranges is 50/60 Hzhere (45 Hz - 0 % 66 Hz + 0 %).

Voltage balance

Because of the uneven loading on the conductor and with thedirect connection of greater power ratings, deviations from theideal voltage form and asymmetrical voltages can be caused inthree-phase AC power networks. In consumers with a three-phasesupply, these asymmetries in the mains voltage can result inuneven loading of of the input phases and therefore to a prema-ture failure of downstream semiconductors, such as diodes inmains rectifiers or thyristors EMS.

If this condition is not fulfilled, or symmetry at the connection loca-tion is not known, the use of a main choke in the mains-side feederunit of the power bus is recommended.

h Measures for electromagnetic compatibility are manda-tory in a magnet system, to meet the legal standards forEMC- and low-voltage regulations.

Total harmonic distortion (THD)

The THD (Total Harmonic Distortion) is a measurement for theoccurring harmonic distortion of the sinusoidal oscillation (mains

power side) input variables. It is given in percent of the total value.

With the RASP Rapid-Link modules, the permitted value for thetotal harmonic distortion THD >120 %.

Idle power compensation devices

Compensation on the power supply side is not required for theRAMO and RASP Rapid-Link modules.

Mains chokes

A main choke (also called commutation choke) increases thereactor of the power supply line. This extends the current flow

period and dampens mains deviations.On RASP, a main choke limits the mains feedback to permissiblevalues. The harmonic current emissions that are fed back into themains network ("mains feedback") are reduced. This reduces themains-side apparent current to about 30 %.

Main chokes attenuate interference from the supply systemtowards RAMO and RASP. This increases the electric strength ofRapid Link modules RAMO and RASP and extends their lifespan.

Main chokes are designed based on the mains-side input current(ILN) of Rapid Link power bus.

U1 = fundamental componentTHD k = 0.1l K = 10 % ~ -20 dB (THD suppression)

THD (Total Harmonic Distortion)

h In the AC power networks with non-choked reactivecurrent compensation devices, current deviations canenable parallel resonance and undefinable circumstances.

In engineering the connection of RAMO and RASP to ACsupply systems with undefined conditions, consider usingmain chokes in the power bus feeder unit.

h For the operation of RAMO and RASP, the application ofmain choke is not necessary. We do recommend howeverthat an upstream main choke is used since the networkquality is not known in most cases.

While planning the project, consider that a main choke isonly assigned to a single Rapid Link power bus for decou-pling.

When using an adapting transformer a main choke is notnecessary.

Safety and switching

Fuses and cable cross-sectionsThe fuses and wire cross-sections allocated for power-side connec-tions depend on the rated mains current ILN of the Rapid Linkpower bus (without mains reactor).

The national and regional standards (for example VDE 0113,EN 60204) must be observed and the necessary approvals (forexample UL) at the site of installation must be fulfilled.

When the device is operated in a UL-approved system, use onlyUL-approved fuses, fuse bases and cables.

The leakage currents to ground (to EN 50178) are greater than3.5 mA. The connection terminals marked PE and the housingmust be connected with the earth-current circuit.

The cross-sections of the cables and cable protection fuses usedmust correspond with local standards.

For an installation in accordance with UL Standards, the fuses andcopper cable that are UL-approved and have a heat-resistance of+60/75 C are to be used.

For a permanent installation with insulation, use power cablesthat are suitable for the specified mains voltages.

For RASP a fully (360) shielded low-impedance-screened cable on

the motor side is required. The length of the motor cable dependson the RFI class and must not exceed 10 m for RASP.

Tripping currents at short-circuit

The tripping current must also be reliably reached in the event ofa short-circuit in one pole. Make sure that the total current of allmotors (including starting currents) or the charging current of allconnected speed control units RASP remains smaller than the trip-ping current when mains power is switched on.

Example: Disconnect Control Unit RA-DI.

Instead of the disconnect control unit RA-DI, you can use a 3-poleminiature circuit-breaker In F 25 A and B or C characteristic.Here, you must observe the following:

The let-through energy I2t in the event of a short-circuit mustnot exceed 29800 A2s.

Therefore the short-circuit current Icc at the mounting locationmust not exceed 10 kA (a characteristic curveFigure 11).

h Attention! When selecting the cable cross-section, take the voltagedrop under load conditions into account.The consideration of other standards (e.g. VDE 0113 orVDE 0289) is the responsibility of the us-er.

h Caution! The specified minimum PE conductor cross-sections (EN 50178, VDE 0160) must be maintained.

h Choose the cross-section of the PE conductor in the motorlines at least as large as the cross-section of the phaselines (U, V, W).

Power bus

The power bus supplies Rapid Link modules RAMO and RASP withmains and auxiliary power. Plug-in outgoers can be quickly and

safely connected at any point along the bus. The power bus canconsist either of a flexible busbar (ribbon cable) or standard roundcables.

Cable length

Observe the following when planning the lengths of the power buscabling:

On a short circuit in one pole at the end of the power bus, forexample in the terminal board of the last consumer, theupstream safety device must trip. The level of short-circuitcurrent depends on: Cable length Conductor cross-section Short-circuit current at the incoming point

The level of the application-specific voltage drop, whichdepends on: Cable length Conductor cross-section

Current consumption of motors

Calculate the short-circuit current and voltage drop according toDIN VDE 0100 to make sure that the protection requirements arefulfilled.

You can calculate the cable length for the power bus as follows:

h Caution! All devices connected to the apparatus and data bus

must also meet the requirements for safe isolationaccording to IEC/EN 60947-1 Annex N orIEC/EN 60950.

Power supply units for the AS-Interface power supplymust meet the safe isolation requirements according toSELV.

For RASP a screened cable is not required on the mainsside.

The sum of mains currents from RAMO and RASP in continuousoperation must not exceed 25 A (power bus 4 mm2).

Residual current device (RCD)

RCD (Residual Current Device): Residual current device, residualcurrent circuit breaker (FI circuit breaker).

Residual current circuit breakers protect persons and animals fromthe existence (not the origination) of impermissibly high touchvoltages. The prevent dangerous, in cases deadly injuries causedby electrical accidents and also serve as fire prevention.

RASP work internally with rectified AC currents. If an error occurs,the DC currents can block an RCD circuit breaker of type A fromtriggering and therefore disable the protective functionality.

On RASP safety-relevant leakage currents can occur during opera-tion when RASP is not earthed (due to a fault).

Leakage currents to ground are mainly caused by foreign capaci-ties with RASP; between the motor phases and the shielding of themotor cable and via the Y-capacitors of the internal radio interfer-ence suppression filter. The size of the leakage current is mainlydependent upon the:

length of the motor cable, shielding of the motor cable, height of the pulse frequency (switching frequency of the

inverter), Radio interference suppression filter type Grounding measures at the site of the motor.

Mains contactor

The mains contactor enables an operational switching on and offof the supply voltage and switching off in case of a fault.

Select the mains contactor according to the total mains-sidecurrent (ILN) of a power bus (F 25 A) and utilization categoryAC-1 (IEC 60947).

EMC compliance

Electrical components in a system (machine) have a reciprocaleffect on each other. Each device not only emits interference but isalso affected by it. The interference can be produced by galvanic,capacitive and/or inductive sources or by electromagnetic radia-tion. In practice, the limit between line-conducted interference andemitted interference is around 30 MHz. Above 30 MHz, cables andconductors act like antennas that radiate electromagnetic waves.

Electromagnetic compatibility (EMC) for frequency-controlleddrives (variable speed drives) RASP is implemented in accordancewith product standard IEC/EN 61800-3. This includes the complete

power drive system (PDS), from the incoming unit to the motor,including all components and cables. This type of drive system canconsist of several individual drives (Rapid Link).

The generic standards of the individual components in a PDScompliant with IEC/EN 61800-3 do not apply. These componentmanufacturers, however, must offer solutions that ensure stan-dards-compliant use.

In Europe, maintaining the EMC Directives is mandatory.

A declaration of conformity (CE) refers always to a "typical"magnet system (PDS). The responsibility to comply with the legallystipulated limit values and thus the provision of electromagneticcompatibility is ultimately the responsibility of the end user orsystem operator. This operator must also take measures to mini-mize or remove emission in the environment concerned (seeFigure14). He must also utilize means to increase the interference immu-nity of the devices of the system.

With their high interference immunity up to category C3, RapidLink modules are ideal for use in harsh industrial networks (2ndenvironment).

With line-conducted emission, RASP with built-in radio interfer-ence suppression filter ensure maintenance of the limit values ofcategory C3. This requires an EMC-compliant installation(a page 48) and the observation of permissible motor cablelengths and the inverters maximum switching frequency (f PWM).

The required EMC measures should be taken into account in the

engineering phase. Improvements and modifications duringmounting and installation or even at the installation site involveadditional and even considerably higher costs.

h In engineering take into account that jog operation of aRapid link module must be carried out only through themodules AS-Interface control input and not through themains contactor.

The maximum permitted operating frequency of the mainsvoltage is one time per minute (normal operation).

09/11 MN03406003Z-EN Data bus ASi

29

Data bus ASi

The AS-Interface data bus is a system solution for networkingdifferent modules. AS-Interface networks are quick and easy toimplement.

Data cable

AS-Interface uses a geometrically coded, unscreened flat cable witha cross-section of 2 1.5 mm2. It is used to transfer both power and

all data traffic between the PLC and I/O and also supplies theconnected devices with energy to a certain extent. The installationmeets the usual requirements. Engineering is simplified by full flexi-bility in system layout and mounting.

When a link is connected to the flat cable, two metal pins piercethrough the cables jacket and into the two cores to establish acontact with the AS-Interface cable. There is no need to cut andstrip cables, apply ferrules or connect individual cores.

Rapid Link function modules can be installed and removed anynumber of times at various locations. The AS-Interface ribboncable is self-healing, dust-tight and resistant to spray-water. The

network can have a star, linear or tree structure.

Data transfer

For transmission the data is modulated onto the supply voltage.Each modules transmitter injects the data signals in the form ofchanges in current. This change in current induces a voltage in thedata coupling coils, which the receivers of all modules along theAS-Interface bus can read.

The cycle time depends on the number of modules along the line(31 possible addresses). With 31 modules the cycle time is about

5 ms and is calculated as follows:150 ms (no. of modules + 1).

The response time to a control signal through an AS-Inter-face busis 25 ms 5 ms plus an AS-Interface cycle time of up to 5 ms.

Head station

The head station, for example interface control unit RA-IN, estab-lishes the connection to the PROFIBUS-DP field bus and, as master,manages all communications within the AS-Interface line.

The head station contains a built-in power extender (PEX) which

contains a data decoupler for up to 2.8 A at 30 VH AS-Interfacevoltage. The AS-Interface power extender is short-circuit-limited(self-resetting fuse, time-delay, 3 A).

The head station requires a power supply unit with 30 VH to AS-Interface specification (SELV, smoothing, etc.) and with or withoutdata decoupling. Several interface control units RA-IN can besupplied by one PSU. For supply cables use standard round cableswith 3 1.5 mm2 or 3 2.5 mm2.

Cable lengths and voltage drop

When planning the lengths of the AS-Interface line cabling,observe the following:

The total length including all spur lines and M12 plug cablesof the function modules (calculate 0.9 m each for 0.5 m longM12 plug cables) must not exceed 100 m. This total lengthdoes not include the length of cabling between PSU and headstation.

Each station must be supplied with at least 24 VH +10/15 %. The head station must be supplied with at least 26 VH.

Calculate current demand and voltage drop to ensure that allsensors, actuators and the head station receive the requiredvoltage.

Length of AS-Interface data cable:The length of the AS-Interface data cable with a cross-section of1.5 mm2 depends on the voltage at the head station and is gener-ally:

AS-Interface voltage > 28 V: 80 m cable length AS-Interface voltage > 26 V: 60 m cable length

Cable length between PSU and head station:The cable length between PSU and a master station is calculatedfrom the voltage drop.

Rapid Link modules RAMO and RASP have two M12 sockets (I3and I4) for direct connection of sensors, for example:

optical (light barriers), inductive (proximity switches), mechanical (end switch).

The length of the sensor connection cables for inputs I3 and I4 islimited to 5 m. The sensors are supplied with 24 V DC from RapidLink modules RAMO and RASP (AS-Inter-face supply voltage). Thetotal current of all sensors is limited to 160 mA. The sensor supplyis short-circuit proof. On overload or short circuit a group faultsignal is generated and indicated by a lit red Motor LED. When thefault has been rectified, the fault signal can be reset with theRESET command.

The input signals of the sensors at I3 and I4 are either incorporateddirectly in the internal controller of RAMO and RASP or transmittedto a higher-level PLC through AS-Interface. Signal conditioningand incorporation in the control sequence is made with a DIPswitch for RAMO (a section "Adjust dip switch, page 68), and

with parameters and DIP switch for RASP (a section "Parame-ters, page 87).

Actuator output O3 (12M connectionsa figure 19) allows actu-ation of external signaling elements or relays. For this pin 2 of O3must be supplied externally with 24 V DC. Reference point is pin1. The actuator (indicator lamp, relay, valve) can be connected topin 4 (+24 V, max. 1 A). Reference point is pin 3.

Figure 19: Connecting example actuator output O3

Actuator output O3 is not actuated directly by I3 or I4 but onlythrough AS-Interface.Response times:

Up to 20 ms About 25 ms 5 ms on quick stop

The connection cable must not be longer than 20 m. The loadcurrent must not exceed the load current of 1 A. Output O3 isshort-circuit proof.

On overload or short circuit a group fault signal is generated andindicated by a lit red Motor LED. The voltage at output O3(24 V DC) is automatically switched off. When the fault has beenrectified, the fault signal can be reset with the RESET command.

Fan connection F

Fan connection F is fitted only on RASP and already assigned bydefault in version RASP-SL-C.

Motor and Application

Motor Selection

General recommendations for motor selection: To the output of Rapid Link modules RAMO and RASP three-phase

AC motors with squirrel-cage rotor and surface-cooling can beconnected; the output is also suitable for three-phase asynchronousmotors. Other motor types, such as external-rotor motors, slip-ringmotors, reluctance motors, or synchronous or servo motors can alsobe connected provided their electrical and connection characteristicsare the same as those of asynchronous motors and their manufac-turer has approved them for the application.

To the frequency-controlled RASP only motors with at leasttemperature class F (155 C max. continuous temperature)should be connected.

Where possible, use four-pole motors (synchronous speed:1500 rpm at 50 Hz or 1800 rpm at 60 Hz).

Operating conditions for S1 operation according to IEC 60034-1.

When operating multiple motors in parallel on one RAMO andRASP, the motor output should not be more than three powerclasses apart.

The rated current of motor and RAMO or RASP should be thesame (avoid overdimensioning the motor).

Motor and circuit type

The motors stator winding can be connected in a star or deltaconfiguration in accordance with the rated operational data on therating plate.

The three-phase motor with rating plate according toFigure 21 can be operated in the Rapid Link system ( ULN= 400 V) only in astar circuit.

The rated operational current of the motor with 2 A at 400 Vrequires a Rapid Link module (RAMO or RASP) with a rated oper-ational current of at least 2 A.

For example:

Automatic deceleration time extension on RASP

In a drive system with AC-supplied motors the energy always flowsfrom the system with the higher frequency to the system with thelower frequency. The difference between the frequencies is theslip. Normally this means that the energy flows from a frequencyinverter to the motor.

If the deceleration is set to a low value at the frequency inverter(a section "P6.6, page 102), the motor may not be able tofollow the deceleration ramp due its or its loads inertia. The direc-

tion of energy flow then reverses and the motors rotational energyis fed back into the frequency inverters internal DC link. Thisresults in an increased DC link voltage and possibly to an over-voltage trip.

To ensure reliable operation without overvoltage trippingfrequency-controlled drives RASP automatically adjust the deceler-ation time to motor and motor load. This prevents overvoltagetripping.

Change of rotation

Three-phase motors work with clockwise rotating fields (viewedfrom the motor shaft) when phase L1 is connected to U1, L2 to V1and L3 to W1. This default operating direction can be reversed

h Notes

RAMO(a section "Motor feeder, page 45) RASP(a section "Motor feeder, page 45,

a section "Motor feeder on RASP, page 47)

h In applications in which the motor can be driven by itsload (for example lowering hoist drives), a RASP withbuilt-in braking resistance should preferably be used. The

braking resistance dissipates the fed back rotationalenergy from the motor as heat. But if the braking resis-tance is destroyed, for example through overload causedby a fault, the RASPs safety trip responds only with adelay because the extended deceleration time takeseffect. The load can therefore drive the motor past theapproached stop position. In applications with finitetravel paths this must be taken into account in the safetyconcept.

The automatic ramp extension function of RASP in regen-erative operation can be disabled with P6.34.

with gearboxes or different mounting positions. On RAMO-Wand RASP the operating direction can be reversed with DIP switch7 without changing the wiring.

With the default settings (switch position Down) a clockwiserotating field is produced with control command FWD, and ananticlockwise rotating field with switch position Up. The LED indi-cates FWD for both directions.

Quick stop

Quick stop is a motor stop function in automatic mode through pin4 of the sensor inputs:

I3/I4 on RAMO I3a/I4a on RASPThe input signals are processed directly in RAMO or RASP. PLC andbus cycle times have no effect on the switch-off times.

Figure 24: Examples: Edge-controlled quick stop in automatic mode(pin 4 = I3 or I3a)

a Internal response timeb Signal O1 from PLC through AS-Interfacec Internal signal to motor output as response to the rising edge of the

sensor at pin 4 (Stop) and to the subsequently rising edge of PLC O1(Start)

The type of edge control (rising, falling) for sensor inputsI3(a)/I4(a) is defined with DIP switches:

DIP 3 on RASP (a page 80) DIP 5 on RAMO (a page 68)

The input signal at pin 4 (rising edge) switches the motor outputoff. When the PLC output (O1) is reset (falling edge), the motoroutput can be switched on again. Whether or not the input signalis still applied when the PLC output is reset or restarted has noeffect.a figure 24.

The "FWD" or "REV" LED flashes when the motor output isswitched off by means of quick stop and the PLC continues to setthe corresponding rotational direction bit.

In operation the FWD or REV LED lights up when the PLC has setthe corresponding direction bit.

Example of quick stop function for a vertical sorter with 360 degreeeccentric.

Quick stop enables precise stopping of the drive when the limitswitch is reached. Through processing in RAMO or RASP the motor

is switched off directly. PLC and bus cycle times have no influenceon the switch-off times.

Interlocked manual mode

In interlocked manual operation damage to conveyed goods orplant through incorrect handling can be avoided. Limit switches

connected to inputs I3 and I4, for example, can be used to reliablylimit the travel path. This function also allows adjustment of, forexample, light barriers before automatic control through a PLC(AS-Interface) is activated.

Figure 26: Interlocked manual operation(example: I3 level-controlled clockwise operation)

a Internal response timeb Selector switch manual modec Output signalIn interlocked manual operation rotating field direction FWD isinhibited after a rising signal edge at I3 or during a continuoussignal. The motor can then be operated only in automatic mode or,with RAMO-W and RASP, in reverse direction in manual mode.Rotating field direction FWD in manual mode is possible again onlyafter a falling edge is registered at I3 or after a changeover toautomatic mode and back again). This also applies for sensor inputI4 and rotating field direction REV.

On RAMO-D interlocked manual operation can be set to act

only edge-controlled with DIP switches 6 and DIP 8 (a page 69).This allows continued manual operation in the same direction aftera break point is reached by simply briefly switching over to Auto-matic and back again.

3 Installation

IntroductionThis chapter describes the mounting and electrical connection ofRapid Link modules RAMO and RASP.

Installation instructions

The mounting instructions in this manual apply for RAMO andRASP with standard equipment and protection type IP65.

For installation instructions, see IL03406019Z for RAMO andIL03406020Z for RASP

Mounting position

Rapid Link modules RAMO and RASP are preferably installed verti-cally.

h During installation and mounting cover the operatorcontrol and display elements and the connectors in thecontrol and power sections to prevent foreign bodiesentering them.

On RASP it is also advisable to protect the cooling finsand, if fitted, the fan from ingress of foreign bodies.

h Perform all installation work with the specified tools andwithout the use of excessive force.

Free space

Depending on version, thermal clearances must be providedaround Rapid Link modules RAMO and RASP. On versions withmanual override switch (RAMO-R and RASP-R) or in thearea of the pluggable cable connectionsb , these must, in addi-tion, provide unobstructed handling. The table below lists therecommended minimum clearances.

Fixing

Rapid Link modules RAMO and RASP are mounted with screws.

Fixing with screwsThe permitted maximum tightening torque for the fixing screws is1.3 Nm (11.5 lb-in).

1) At an installation altitude up to 1000 m and at an ambient temper-ature of up to +40 C no clearance is required to the sides. Higherambient temperatures (up to a maximum of +50 C), pulse frequen-

cies f PWM (up to maximum 16 kHz) and installation altitudes (up to2000 m) require clearance on all sides of at least 20 mm.

h Clearance dimensions from the mounting base of RAMOand RASP.

h For mobile installation with two prefitted screws(a page 39 and page 39) larger clearances are requiredfor handling.

h Devices with high magnetic fields (e. g. reactors or trans-formers) should not be mounted close to the RAMO and

RASP.

h Install the RAMO and RASP only on a nonflammablemounting base (e.g., on a metal plate).

h For dimensions and weights of RAMO and RASP see thetechnical data (pagea section "Dimensions, page125).

Arrangement of power terminals

The standard arrangement of power terminals is vertical down-wards on versions RAMO--C32 and RASP--C32. A hori-

zontal arrangement (RA-C31 or RA-C33) is not avail-able on all versions.If necessary, briefed specialists can rotate the black enclosure base tothe right or left by 90 degrees. To do this, remove the four screws inthe enclosure cover.

Fix the enclosure cover at the side and lift off carefully.

The enclosure base can now be rotated, for example 90 degreescounterclockwise (to the left). The power terminals now point tothe right. This corresponds with version -C31. With a rotation tothe right they correspond with version -C33.

Finally carefully refit the enclosure cover.

With the four screws secure the enclosure cover on the base.Tighten the screws in two passes, always tightening two diago-nally opposite screws at a time. For example, tighten all fourscrews to about 2 Nm and then to 5 Nm, always working in acrosswise pattern.

Electrical Installation Power bus

The Rapid Link system can have one of two types of power bus:

Flexible (RA-C1...) busbar Round conductor (standard cable)

Flexible (RA-C1-7...) busbarFlexible busbar RA-C1-7 is coded for protected against polarityreversal: One edge of the busbar is wedge-shaped. The busbarconnectors of all system components (ribbon cable outgoers) isshaped accordingly. The flexible busbar is inserted such that thewedge-shaped side is opposite the hinge of the opened busbarconnector.

Laying the flexible busbarUnreel the flexible busbar, cut to length and lay it. An inscriptionon one side of the busbar provides guidance for coding. A metricmarker on the jacket aids with cutting to length.

Where the flexible busbar is not laid within cable ducts, secure itto the ground with cable binders or cable clamps.

j Danger!Electric shock hazard - risk of injuries!

Carry out wiring work only if the unit is de-energized.

h Caution!Fire hazard!

Only use cables, protective switches, and contactors thatfeature the indicated permissible nominal current value.

h Caution!With RASP earth leakage currents are greater than 3.5 mA(AC). According to product standard IEC/EN 61800-5-1

an additional protective conductor must therefore beconnected to the RASPs heat sink.

j Danger!The components in the RASP power section remain ener-gized up to five (5) minutes after the supply voltage hasbeen switched off (intermediate circuit capacitordischarging time).

On RASP the motor feeder cable must be disconnected orwork on the motor terminal box performed only after thedischarging time.

h Complete the following steps with the specified tools andwithout using force.

End-pieces and lead-throughsOnce the flexible busbar has been laid, all free busbar ends mustbe safely terminated and sealed to IP65. To do this, use cable endpieces (RA-C1-END1) or bushings (RA-C1-DF).

With bushing RA-C1-DF the flexible busbar can be fed into distri-bution module RA-C1-VM-7 in a control panel.

X Cut the busbar to the required length.

X Strip the flexible busbar to the required length (see also notebelow): for cable end piece to 19 mm, for distributor module to 50 mm, for control panel as required.

End-piece mountingX First slide the lower (shorter) part of busbar end piece RA-C1-

END1 onto the prepared flexible busbar.

X Slot the individual conductors into the insulation channels in thebusbar end piece up to the stop.

X Join the upper and lower sections with the two screws. Installedcorrectly, the flexible busbar offers protection type IP65.

Connections, flexible busbar junctionFeeder and outgoer modules can be connected at any point alongthe flexible busbar without interrupting the busbars conductors.The connection is made with contact screws.

Round conductorRound cable junction RA-C2-S1-4 is a T-piece for plug-in poweradapter cable RA-C3/C2-1,5HF. It allows direct connection of aRapid Link module (RAMO or RASP).

Insulation piercing terminals are used for conductor contacting inthe power bus. The Die bushings are dimensioned for a conductorwith outer diameter from 10 to 16 mm.

Accessories (seal insert, locking clip, the fully wired bushing insert,etc.) is included as standard.

X For mounting the round cable junction is secured to the

substrate with suitable screws (M5).X Strip the round cables to a length of 130 mm (two radial cuts,

one longitudinal cut), for example with wire stripper AM16 fromWeidmller.

X Make a radial cut in the gaskets, lay the seals around the cable jacket and insert it in the provided U-shaped contour in thecable junction.

X Insert the conductors into the insulation piercing terminal andsecure them with the screws one at a time.

Assignment of terminals and conductors:

X Turn in the screws [1] all the way to the stop (tightening torque0.5 to 1 Nm).

X Place the cover on the base so that it rests fully on the base. Thescrews must be turned in all the way.

X Secure the cover with the four screws.(size Pozidriv 2; 1.5 to 2 Nm).

X To ensure protection type IP65 on cable binder [2] must befirmly tightened about each of the outer gaskets.

X Slot the attached locking clip for the outgoer plug onto the twostuds of the bushing housing.

Round conductor with Power boxPower box RA-C4-PB65 is a contact unit for uncut round cablesfrom 2.5 to 6 mm2, with protection type IP65.

h To strip the cable, set the blade so that the conductorinsulation remains undamaged.

h The supplied equipment includes two pairs of seals forcable outer diameters from 10 to 13 mm and from 13 to16 m. Only these matched gasket inserts guaranteeprotection type IP65 when used correctly.

Pins 5 and 8 of the motor feeder socket are used for monitoringthe motor cable and for thermistor protection.

On motors without thermistor the cable ends (pins 5 and 8) mustbe connected in the motors terminal box).

On motor cables without the conductors for pins 5 and 8 (forexample 4-core motor cables) the two connections must beconnected directly in the motor plug.

External brakeA mechanical spring-loaded brake fitted to the motor (disk orspring-applied brake) brakes the motor shafts rotating motionwhen the brake coils supply voltage is switched off. If the brake isrequired to engage quickly, DC air solenoids are used. The brakeis, in this case, supplied with AC through a functional rectifier builtinto the motor.

Rapid Link modules RAMO and RASP contain a faster electronicswitch for supplying and actuating the external motor brake with230 V AC. It is connected with pins 4 and 6 of the motor feedersocket. The highest permissible continuous holding current is0.6 A. For releasing the brake, up to 6 A are available for up to120 ms.

The external brake is actuated as follows:

With RAMO automatically with the start signal, in automaticand manual modes.

With RASP by the built-in frequency inverter (a section"Braking (P12), page 114).

h The PE connection of the motor feeder socket isconnected directly with the PE connection of the powerplug.
