can be checked.
∗ Time Stamps
A function that measures the ON times of the control power supply and main circuit power supply in 100-ms
units and displays the total operating time when an alarm occurs. The time stamp operates around the clock for
approximately 13 years.
<Example of Time Stamps>
If 36000 is displayed,
3600000 [ms] = 3600 [s] = 60 [min] = 1 [h]
Therefore, the total number of operating hours is 1 hour.
(1) Preparation
There are no tasks that must be performed before displaying the alarm history.
(2) Operating Procedure
Use the following procedure.
Note:
• If the same alarm occurs after more than one hour, the alarm will be saved. If it occurs in less than one hour, it
will not be saved.
• The display ".---" means no alarm occurs.
• Delete the alarm history using the parameter Fn006. The alarm history is not cleared on alarm reset or when the
main circuit power supply to the SERVOPACK and converter is turned OFF.
