An external +24V I/O power supply is required since there is no +24V power source available inside the servo drive.
Output → ALM+CN1_A/B/C-4
Servo alarm output
Output → ALM- CN1_A/B/C-3
Servo alarm output uses grounding signal
ALM outputs a signal when the servo drive is detected in an abnormal state.

Alarm state
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.
