Only after an over-current OC or over-voltage OV fault occurs, the AC motor 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 motor drive will restart with speed search, which starts at the frequency before the
fault. To set the waiting time before restart after a fault, please set Pr. 08-06 Base Block Time for Speed
Search.

Auto Reset Time at Restart after Fault Unit: 1
Settings 00 to 60000 sec Factory Setting: 600

This parameter should be used in conjunction with Pr.08-14.
For example: If Pr.08-14 is set to 10 and Pr.08-21 is set to 600s (10 min), and if there is no fault for over
600 seconds from the restart for the previous fault, the auto reset times for restart after fault will be reset to
10.
