4.11.1 Servo alarm output

The following diagram shows the right way to connect the Alarm Output.
An external +24V I/O power supply is required since there is no +24V power source available inside the servo drive.
Output → ALM+ 1CN- 7
Output → ALM- 1CN- 8
ALM outputs a signal when the servo drive is detected in an abnormal state.
Normally, the external circuit consists of /ALM should be able to switch off the power of servo drive.
Signal Status
ON
ALM
OFF
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.
→ Input /ALM-RST 1CN- 39
Signal Status
ON
/ALM-RST
OFF
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.
