6.4.3 Using More Than One SERVOPACK
The following diagram is an example of the wiring when more than one SERVOPACK is used.
Connect the alarm output (ALM) terminals for the three SERVOPACKs in series to enable alarm detection relay
1Ry to operate.
When the alarm occurs, the ALM output signal transistor is turned OFF.
Multiple servos can share a single molded-case circuit breaker (QF) or noise filter. Always select a QF or noise
filter that has enough capacity for the total power capacity (load conditions) of those servos. For details, refer to
2.5.2 Molded-case Circuit Breaker and Fuse Capacity

Note: Wire the system, so that the phase-S power supply will be the ground phase.
