8.1 Alarm and warning list
When an error occurs during operation, the corresponding alarm or warning is displayed. When the alarm or
the warning occurs, refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" to
remove the failure. When an alarm occurs, ALM will turn off.
After its cause has been removed, the alarm can be deactivated in any of the methods marked ż in the
alarm deactivation column in the following table. Warnings are automatically canceled after the cause of
occurrence is removed.
For the alarms and warnings written "SD" in the stop method column, the axis stops with the dynamic brake
after forced stop deceleration. For the alarms and warnings written "DB" in the stop method column, the axis
stops with the dynamic brake without forced stop deceleration.
