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.
