Figure 12.12 -
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 "DCbreak" status at the keypad (HMI) top left corner.
