• Function
A large braking torque can be obtained by applying a direct current to the motor. These parameters
set the direct current to be applied to the motor, the application time and the starting frequency.

DC braking current
Note1: During DC braking, the overload protection sensitivity of the inverter increases. The DC braking
current may be adjusted automatically to prevent tripping.
Note 2: During DC braking, the carrier frequency is 6kHz irrespective of the setting of parameter
(PWM carrier frequency).
