Wiring and Connection
3.1.5 Using More Than One SERVOPACK
This section shows an example of the wiring and the precautions when more than one SERVOPACK is used.
(1) Wiring Example
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.
(2) Precautions
Multiple SERVOPACKs 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.
