This section describes how to use the basic operations described in section 1 to operate and
adjust the motor.
4.2.1 Operation in Alarm Trace-back Mode
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 196.
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 Section 4.2.6 Clearing Alarm Trace-back Data for details.
