CAUTION
If an absolute position counter warning (E3. ) occurred, always make home position
setting again. Not doing so may cause unexpected operation.
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.
Main circuit device overheat warning (91. )
Excessive regenerative warning (E0. )
Overload warning 1 (E1. )
When a warning whose stop method is all axis stop in the following table occurs, the servo amplifier goes into
the servo-off status and the servo motor stops at the warning occurrence.
If any other warning occurs, operation can be continued but an alarm may take place or proper operation may
not be performed.
Remove the cause of warning according to this section. Use the MR Configurator to refer to a factor of warning
occurrence.
