Function group 1: Select 1 (DC brake to stop) in F4 code
F8: Initial frequency for DC brake
F9: Waiting time of inverter before DC brake
F10: Set as per the rated current of motor (based on H33)
F11: The time set shall be the time for work of DC braking voltage
Caution
The over-voltage or overlong time in DC brake will cause overheat or damage of motor.
Setting F10 or F11 to 0 will disable DC brake.
Waiting time of DC brake: When load inertia is large or DC
Brake Start Frequency is high, over current trip may occur. It
can be prevented using F9.
In case of DC brake at high load inertia and frequency,
change the DC brake controller gain according to H37 set
value.
