3 Wiring and Connection3.1.5 Using More Than One SERVOPACK3-163.1.5 Using More Than One SERVOPACKThis section shows an example of the wiring and the precautions when more than one SERVOPACK is used.(1) Wiring ExampleConnect the alarm output (ALM) terminals for three SERVOPACKs in series to enable alarm detection relay1RY to operate. When the alarm occurs, the ALM output signal transistor is turned OFF.(2) PrecautionsMultiple SERVOPACKs can share a single molded-case circuit breaker (1QF) or noise filter. Always select amolded-case circuit breaker or noise filter that has enough capacity for the total power supply capacity (loadconditions) of the SERVOPACKs.R S T1QF2KM1Ry+24 VL1L2L3L1C0 VL2C1FLTML1L2L3L1L2L3L1C1DL2CMML1CL2C3SA1KM1PL1KM2KM1SA2SA34CN11KM1Ry1KMALM+ALM−34CN1ALM−34CN1ALM−1RyALM+ALM+SERVOPACKServomotorServomotorServomotorRelayterminalRelayterminalRelayterminal1QF:1FLT:1KM: Magnetic contactor(for control power supply)2KM:(for main circuit power supply)1Ry:1PL:1SA:2SA:3SA:1D:Molded-case circuit breakerNoise filterRelayMagnetic contactorIndicator lampSurge absorberSERVOPACKSERVOPACKSurge absorberSurge absorberFlywheel diodesupply ONPower supplyRelayterminal(For servo alarmdisplay)Servo powersupply OFFServo power
