4.2.1 Operation in Alarm Trace-back Mode
1) The alarm trace-back mode displays up to ten alarms which occurred previously. By al-
lowing confirmation of what alarm occurred when, it is a useful aid to speed up trouble-
shooting.
Alarm Sequence Number Alarm Code
The higher the number,
the older the alarm data
See the table of
alarms on page 185.
NOTE The alarm trace-back data is not cleared on alarm reset or when the Servopack power is
turned OFF. This does not adversely affect operation.
The data is cleared using the special mode: Clear alarm trace-back data.
Refer to sub-section 4.2.6 for details.
