Figure 12.10:
DC braking operation via general disabling – V/f mode
For the V/f scalar control mode there is a “dead time” (motor rotates free), before starting the DC braking. This
time is necessary to the demagnetization of the motor and it is proportional to its speed.
During the DC braking the inverter indicates the “RUN” status at the keypad (HMI).
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.
