1.4 Remedies for alarms

CAUTION

When any alarm has occurred, eliminate its cause, ensure safety, and deactivate
the alarm before restarting operation. Otherwise, it may cause injury.
If [AL. 25 Absolute position erased] occurs, always make home position setting
again. Otherwise, it may cause an unexpected operation.
As soon as an alarm occurs, make the Servo-off status and interrupt the main
circuit power.

POINT

When any of the following alarms has occurred, do not cycle the power
repeatedly to restart. Doing so will cause a malfunction of the servo amplifier
and servo motor. Remove its cause and allow about 30 minutes for cooling
before resuming the operation.

[AL. 30 Regenerative error]

[AL. 45 Main circuit device overheat]

[AL. 46 Servo motor overheat]

[AL. 50 Overload 1]

[AL. 51 Overload 2]

[AL. 37 Parameter error] is not recorded in the alarm history.

Remove the cause of the alarm in accordance with this section. Use MR Configurator2 to refer to the cause
of alarm occurrence.
