Parameter Groups
‑243‑
Max.: 2000 Data type: UInt16
Default:
760
Change: In real time
Value Range:
200.0 V to 2000.0 V
Description
Used to adjust the energy consumption efficiency of the braking resistor. When
the motor is in the power generation state, the voltage of the DC bus in the AC
drive will rise. The braking unit can be used to control the voltage of the DC bus to
consume the regenerative electric energy generated by the motor through the
braking resistor or send back the regenerative electric energy to the power
supply.
Application scenarios:
In the V/f control mode, if the actual deceleration time of the motor is far longer
than the set deceleration time, the motor decelerates too slowly. To enable the
motor to decelerate quickly by enhancing the energy consumption of the braking
resistor, you can set F9‑08 (Braking unit applied voltage) to 690 V if the following
conditions are met: The AC drive is equipped with a braking resistor or an energy
feedback unit; The input voltage of the AC drive is 360 V to 420 V.

Max.: 20 Data type: UInt16
Default:
0
Change: In real time
Value Range:
0–20
Description
This parameter defines the number of auto fault reset attempts of the AC drive. If
the number of reset attempts exceeds the value of this parameter, the AC drive
will remain in the faulty state.

Max.: 1 Data type: UInt16
Default:
0
Change: In real time
Value Range:
0: Not act
1: Act
