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 00 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.
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 Time for
restart after fault will be reset to 10.

When automatic energy-saving function is enabled, it will operate with full voltage during
acceleration/deceleration. For the constant speed, it will give the best voltage which is auto
calculated by the load power to load.
