6.7 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.

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 becomes the setting of parameter f300 (PWM carrier
frequency).
Note 3: DC breaking can be done by using terminal input. Input terminal 22: Assign DC braking command
(23 is reverse).
DC braking is applied while the terminal is ON, regardless of the , settings. Even if
the terminal is OFF, DC braking is applied only for the time.
The amount of DC braking depends on the settings.
