
The inverter begins accelerating after
the frequency setting signal has reached
point B.
Deceleration begins when the frequency
setting signal decreases below point A.

6.7 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.
