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 and then restarts automatically. You can limit
the number of resets in a specified time period, and you can set
up automatic resets for a variety of faults.
