and the rotation direction is unknown. It is easy to cause over
current protection in start. Therefore, before start, you shall use DC
injection brake to stop the motor in advance.
Dc braking current in start is the ratio of rated current of inverter,
adjusting P204 can have different braking torques. While setting
value of parameter, you can adjust it from low to high until a
sufficient braking torque is reached according to the actual load.
Dc braking time is the period DC injection brake lasts. When it is 0,
DC injection brake is invalid.

Dc braking in stop is application for load which has requirement on
braking.
Dc braking current in stop is the ratio of rated current of inverter.
Adjusting this parameter can have different braking torques.
Dc braking time in stop is the period DC injection brake mode lasts.
When it is 0, DC injection brake is invalid.
Refer to the explanations of P203, P204 and P205 for relevant
details.
