DC braking

6.7.1 DC braking
: DC braking starting frequency
: DC braking current
: DC braking time
• 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 starting frequency
DC braking current
DC braking time
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).
