Using More Than One SERVOPACK
Connect the ALM (Servo Alarm Output) signal for these SERVOPACKs in series to operate the
alarm detection relay (1RY).
When a SERVOPACK alarm is activated, the ALM signal transistor turns OFF.
The following diagram shows the wiring to stop all of the Servomotors when there is an alarm
for any one SERVOPACK.
More than one SERVOPACK can share a single Noise Filter. However, always select a Noise Fil-
ter that has a large enough capacity to handle the total power supply capacity of all the
SERVOPACKs. Be sure to consider the load conditions.
