14.6 Troubleshooting
POINT
If an alarm which indicates each axis in the stop method column occurs, the axis
without the alarm operates the servo motor as per normal.
If an alarm/warning has occurred, refer to this section and remove its cause.
14.6.1 Alarm and warning list
When an error occurs during operation, the corresponding alarm or warning is displayed. Refer to section 14.6.2
and 8.3 for alarms, and section 14.6.3 and 8.4 for warnings to take an appropriate action. When an alarm occurs,
ALM-A/ALM-B will turn off.
After its cause has been removed, the alarm can be deactivated in any of the methods marked in the alarm
deactivation column. Warnings are automatically canceled after the cause of occurrence is removed.
