an unexpected operation.
When any of the following alarms has occurred, 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.

If [AL. E6], [AL. E7], [AL. E9], [AL. EA], or [AL. EB] occurs, the amplifier will be the servo-off status. If any other warning
occurs, operation can be continued but an alarm may take place or proper operation may not be performed.
