14.6.3 Remedies for warnings
CAUTION
If Absolute position counter warning (E3. ) occurs, always make home position
setting again. Otherwise, it may cause an unexpected operation.
POINT
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 direct drive 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.
Excessive regeneration warning (E0. )
Main circuit device overheat warning (91. )
Overload warning (E1. )
Direct drive motor overheat warning (E2. )
When a warning whose stop system is "All axis" in the following table occurs, the servo amplifier will be the
servo-off status and the servo motor will stop 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.
Eliminate the cause of the warning according to this section. Use MR Configurator to refer to the cause of
warning occurrence.
