6.6 DC braking
6.6.1 DC braking
H : DC braking starting frequency (Hz)
H : DC braking current (%)
H : DC braking time (s)
• Function
Large braking torque can be obtained by applying a direct current to the motor. These
parameters are used to set the direct current to be applied to the motor, the application time
and the starting frequency.

Note: During DC braking, the overload protection sensitivity of the motor increases. To prevent
tripping, the DC braking current is adjusted automatically in some cases.
