4.5. Other Output Signals
4.5.1. Servo alarm output
The following diagram shows the right way to connect Alarm Output.
Ex24 V I/O power supply is required, since there is no +24 V power supply available inside servo
drive.
The signal outputs when servodrive is detected abnormal.
Normally, the external circuit consists of /ALM should be able to switch off power of servo drive.
When “servo alarm (ALM)” happens, always remove alarm reasons first, and then turn the input signal
"/ALM-RST" to ON position to reset alarm status.
Normally, the external circuit can switch off power supply of servo drive when alarm occurs. When servo
drive is re-switched on, it removes alarm automatically, so normally alarm reset signal is not required to
be connected.
In addition, alarm reset are enabled with panel operator.
Note:
When alarm occurs, always remove alarm reasons before resetting alarms.
