Alarms - Omron OMNUC G5 R88M-K series User Manual

11-3 Alarms

If the Servo Drive detects an error, it outputs an alarm (ALM), turns off the power drive circuit,
and displays the error number on the front panel.
Precautions for Correct Use
 Refer to "Error Diagnosis Using the Alarm Displays" (P.11-15) for appropriate alarm measures.
 Reset the alarm using one of the following methods. Remove the cause of the alarm first.
• Turn OFF the power supply, then turn it ON again.
• Reset the alarm via MECHATROLINK-II communications or on CX-Drive.
However, some alarms can only be reset by turning the power supply OFF then ON again. Refer
to the "Alarm List" (P.11-7).
 If you reset an alarm while the operation command (RUN) is turned ON, the Servo Drive starts
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.
 The Overload (Alarm No.16) cannot be reset for 10 seconds once it occurs.
 Any displays such as hh, FF, and HH on the error number mean internal malfunction on the MPU.
Cut off the power immediately when you encounter such a case.
