An ex24V I/O power supply is required since there is no +24V power source available inside the servo drive.

Output → ALM- 1CN- 8
Servo alarm output uses grounding signal
ALM outputs a signal when the servo drive is detected in an abnormal state.

Do not reset servo alarm
Normally, the external circuit can switch off the power supply of the servo drive when an alarm occurs. When
powered on again, the servo drive removes the alarm automatically, so the alarm reset is not required to be connected. In
addition, the alarm reset is enabled with the panel operator.
Note: When an alarm occurs, remove the alarm reason before resetting the alarms.
