(2) Multi-axis Application
Connect the alarm output (ALM) terminals for three SERVOPACKs in series to enable alarm detection relay
1RY to operate. When the alarm occurs, the ALM output signal transistor is turned OFF.
The following diagram shows a wiring example for three-phase, 400-VAC SERVOPACK with converter.
Precautions
Multiple SERVOPACKs and converters can share a single molded-case circuit breaker (1QF) or noise filter.
Always select a molded-case circuit breaker or noise filter that has enough capacity for the total power supply
capacity (load conditions) of the SERVOPACKs and converters.
