Explanation: 0: Invalid 1: Valid
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 DCbus voltage
returns to allowable value, inverter will resume the deceleration.
Default value 1
Automatic voltage regulation selection
P412
Setting Range:0~2 Unit:1
Explanation: 0: Invalid 1: Valid 2: Invalid when decelerating
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.
2: Invalid when decelerating: when this function is selected, braking function of
inverter can be strengthened.
