Group 31: Automatic Reset
This group defines conditions for automatic resets. An automatic reset occurs after a particular fault is
detected. The drive holds for a set delay time, then automatically restarts. You can limit the number of
resets in a specified time period, and you can set up automatic resets for a variety of faults.
