2WIRINGMain circuit terminal specifications2.2.4 When connecting the control circuit and the main circuit separatelyto the power supply (separate power)MCR/L1 InverterS/L2T/L3R1/L11S1/L21When fault occurs, opening of the electromagnetic contactor (MC) on theinverter power supply side results in power loss in the control circuit,disabling the fault output signal retention. Terminals R1/L11 and S1/L21 areprovided to hold a fault signal. In this case, connect the power supplyterminals R1/L11 and S1/L21 of the control circuit to the primary side of theMC.Remove the jumper1)Remove the upper screws.2)Remove the lower screws.3)Pull the jumper toward you toremove.4) Connect the separate power supplycable for the control circuit to theupper terminals (R1/L11, S1/L21).Never connect the power cable tothe terminals in the lower stand.Doing so will damage the inverter.MCR/L1S/L2 T/L3R1/ S1/L11 L21 Power supplyterminal blockfor the control circuit3)Power supply terminal blockfor the control circuitR1/L11S1/L21Main power supplyFR-A721-5.5K to 15KFR-A741-5.5K to 15K1)2)4)FR-A721-18.5K to 55KFR-A741-18.5K to 55KPower supplyterminal block forthe control circuitCAUTION· Do not turn off the control power (terminals R1/L11 and S1/L21) with the main circuit power (R/L1, S/L2, T/L3) on. Doing so maydamage the inverter. Make up a circuit which will switch off the main circuit power supply terminals R/L1, S/L2, T/L3 when thecontrol circuit power supply terminals R1/L11, S1/L21 are switched off.· Be sure to use the inverter with the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 removed when supplying powerfrom other sources. The inverter may be damaged if you do not remove the jumper.· The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than theprimary side of the MC.· When separate power is supplied from R1/L11 and S1/L21, the power capacity necessary for the 15K or less is 90VA, for the18.5K or more is 100VA.· If the main circuit power is switched off (for 0.1s or more) then on again, the inverter resets and a fault output will not be held.21
Control circuit specifications2.3 Control circuit specifications2.3.1 Control circuit terminalsindicates that terminal functions can be selected using Pr. 178 to Pr. 196 (I/O terminal function selection) (Refer to page 206.)(1) Input signalsTypeTerminalSymbolTerminalNameDescriptionRatedSpecificationsRefer topageContact inputSTFSTRSTOPRH,RM, RLJOGRTMRSRESAUCSSDPCForwardrotation startReverserotation startStart selfholdingselectionMulti-speedselectionJog modeselectionPulse traininputSecondfunctionselectionOutput stopResetTerminal 4inputselectionPTC inputSelection ofautomaticrestart afterinstantaneouspower failureContact inputcommon (sink)(initial setting)Externaltransistorcommon(source)24VDC powersupplycommonExternaltransistorcommon (sink)(initial setting)Contact inputcommon(source)24VDC powersupplyTurn on the STF signal to start forwardrotation and turn it off to stop.Turn on the STR signal to start reverserotation and turn it off to stop.When the STF and STRsignals are turned onsimultaneously, the stopcommand is given.Input resistance4.7kΩVoltage at opening:Turn on the STOP signal to self-hold the start signal. 21 to 27VDCContacts at shortcircuited:2064 toMulti-speed can be selected according to the combination of RH,RM and RL signals.6mADC206Turn on the JOG signal to select Jog operation (initial setting) andturn on the start signal (STF or STR) to start Jog operation.JOG terminal can be used as pulse train input terminal. To use aspulse train input terminal, the Pr. 291 setting needs to be changed.(maximum input pulse: 100kpulses/s)Turn on the RT signal to select second function.When the second function such as "second torque boost" and"second V/F (base frequency)" are set, turning on the RT signalselects these functions.Turn on the MRS signal (20ms or more) to stop the inverter output.Use to shut off the inverter output when stopping the motor byelectromagnetic brake.Used to reset fault output provided when fault occurs.Turn on the RES signal for more than 0.1s, then turn it off.Initial setting is for reset always. By setting Pr. 75, reset can be setto enabled only at fault occurrence. Recover about 1s after resetis cancelled.Terminal 4 is made valid only when the AU signal is turned on. (Thefrequency setting signal can be set between 4 and 20mADC.)Turning the AU signal on makes terminal 2 (voltage input) invalid.AU terminal is used as PTC input terminal (thermal protection ofthe motor). When using it as PTC input terminal, set the AU/PTCswitch to PTC.When the CS signal is left on, the inverter restarts automatically atpower restoration. Note that restart setting is necessary for thisoperation. In the initial setting, a restart is disabled.(Refer to Pr. 57 Restart coasting time in page 239)Common terminal for contact input terminal (sink logic) and terminalFM.When connecting the transistor output (open collector output),such as a programmable controller, when source logic isselected, connect the external power supply common fortransistor output to this terminal to prevent a malfunction causedby undesirable currents.Common output terminal for 24VDC 0.1A power supply (PCterminal).Isolated from terminals 5 and SE.When connecting the transistor output (open collector output), suchas a programmable controller, when sink logic is selected, connectthe external power supply common for transistor output to thisterminal to prevent a malfunction caused by undesirable currents.Common terminal for contact input terminal (source logic).Can be used as 24VDC 0.1A power supply.Input resistance2kΩContacts at shortcircuited:8 to13mADCInput resistance4.7kΩVoltage at opening:21 to 27VDCContacts at shortcircuited:4 to6mADC206206206206206206259168206----------------- —Power supplyvoltage range 19.2to 28.8VDCPermissible loadcurrent 100mA2622
