Auto Restart After Fault

Settings
After fault occurs (allowable faults: over-current OC, over-voltage OV), the AC drive can
be reset/restarted automatically up to 10 times. Setting this parameter to 0 will disable
the reset/restart operation after any fault has occurred. When enabled, the AC drive will
restart with speed search, which starts at the Master Frequency.
