1.5 Remedies for warnings

CAUTION
If [AL. E6], [AL. E7], or [AL. E9] occurs, the amplifier will be the servo-off status. If any other warning occurs,
operation can be continued but an alarm may take place and proper operation may not be performed.
Remove the cause of warning according to this section. Refer to the cause of warning with MR
Configurator2.
If [AL. E3 Absolute position counter warning] occurs, always make the home
position setting again. Otherwise, it may cause an unexpected operation.
POINT
When any of the following alarms occurs, do not cycle the power of the servo
amplifier repeatedly to restart. Doing so will cause a malfunction of the servo
amplifier and servo motor. If the power of the servo amplifier is switched off/on
during the alarms, allow more than 30 minutes for cooling before resuming
operation.
[AL. 91 Servo amplifier overheat warning]
[AL. E0 Excessive regeneration warning]
[AL. E1 Overload warning 1]
