Detection Timing • SERVOPACK alarms are continuously monitored by the alarm management section.
Processing when
Alarm Occurs
• The current command will be aborted.
If a SERVOPACK error is detected during execution of a POSING command, the positioning will be
aborted and the axis will decelerate to a stop.
• The Command Error Completed Status in the Motion Command Status (IW 09,bit 3) will turn ON.
Error and Cause
• The cause of the error depends on the type of alarm. The contents of an alarm is monitored in IW 2D.
Refer to the list of SERVOPACK alarms in 12.5.3 ( 2 ) Servo Driver Alarm Code (IW 2D) for details.
Correction
• Confirm the SERVOPACK alarm and remove the cause.
• Reset the alarm.
