0: Invalid
During deceleration, the DC-bus voltage may increase, when over-
voltage prevention selection is invalid, inverter may trip for over
voltage.
1: Valid
During deceleration, when DC-bus voltage reaches the setting
value, inverter will stop the deceleration procedure. When DC-
bus voltage returns to allowable value, inverter will resume the
deceleration.

If the input voltage is not stable, temperature of the machinery will
increase, insulation may be damaged, and output torque will be
instable.
0: Invalid
Select automatic voltage regulation to be invalid, inverter output
voltage fluctuates.
1: Automatic voltage regulation is valid.
Automatic voltage regulation function is selected, and under the
condition that input electric source is instable, inverter output stable
voltage automatically.
