3.2 Applications
This section describes the applications of the Digital Operator’s basic operations for
operating and adjusting the motor. Be sure to read 3.1 Basic Operations before reading
this section.
3.2.1 Operation in Alarm Traceback Mode
The alarm traceback mode displays up to ten alarms that occurred previously. Allowing con-
firmation of what alarm occurred when, is a useful aid to speed up troubleshooting.
The alarm traceback data is not cleared when the alarm is reset or when the Servopack pow-
er is turned OFF. The alarm traceback data does not prevent the Servopack from operating
properly. Use the special operation to clear alarm traceback data to clear the data. Refer to
3.2.6 Clearing Alarm Traceback Data for details.
