11.4.3 Remedies for warnings
CAUTION
If an absolute position counter warning (AE3) occurred, always make home
position setting again. Otherwise, misoperation may occur.
POINT
When any of the following alarms has occurred, do not resume operation by
switching power of the servo amplifier OFF/ON repeatedly. The servo
amplifier and servo motor may become faulty. If the power of the servo
amplifier is switched OFF/ON during the alarms, allow more than 30 minutes
for cooling before resuming operation.
Excessive regenerative warning (AE0)
Overload warning 1 (AE1)
If AL.E6 or AL.EA occurs, the servo off status is established. If any other warning occurs, operation can be
continued but an alarm may take place or proper operation may not be performed. Use the optional servo
configuration software to refer to the cause of warning.
Remove the cause of warning according to this section. Use the optional MR Configurator to refer to a factor
of warning occurrence.
