Functions Common to All the Control Modes
During the braking process, if the inverter is enabled, the braking is interrupted and the inverter will operate normally
again.
ATTENTION!
The DC Braking may continue active after the motor has already stopped. Be careful with the motor
thermal sizing for short period cyclic braking.
P0301 – DC-Braking Speed
Adjustable
Range:
Properties:
Access groups
via HMI:
Description:
This parameter establishes the beginning point for the DC braking application at stopping. Refer to the
on page 12-21 (a) and (b).
P0302 – DC-Braking Voltage
Adjustable
Range:
Properties:
Access groups
via HMI:
Description:
This parameter adjusts the DC voltage (braking torque) applied to the motor during the braking.
The adjustment must be done by increasing gradually the P0302 value, which varies from 0 to 10 % of the rated
voltage, until getting the desired braking.
This parameter works only for the V/f scalar and VVW control modes.
