11-3 Alarm List
If the driver detects an error, the alarm output (ALM) will turn ON, the power drive circuit in the
driver will turn OFF, and the alarm code will be displayed.
Precautions for Correct Use
Refer to "Error Diagnosis Using the Alarm Displays"(P.11-9) for appropriate alarm measures.
Release the alarm using one of the following methods. Remove the cause of the alarm first.
• Input the alarm reset input (RESET) signal.
• Turn OFF the power supply, then turn it ON again.
• Execute the alarm reset on the Parameter Unit.
However, some alarms can only be reset by turning the power supply OFF then ON again. Refer
to the next item "Alarm List".
If you release an alarm while the operation command (RUN) is turned ON, the Servo Drive will
start operation as soon as the alarm is released, which is dangerous. Be sure to turn OFF the RUN
before clearing the alarm.
If the RUN is always ON, first check safety sufficiently before clearing the alarm.
