0 to 100%

Factory Setting: 0

This parameter sets the level of DC Brake Current output to the motor during start-up and

stopping. When setting DC Brake Current, the Rated Current (Pr.00.01) is regarded as 100%.

It is recommended to start with a low DC Brake Current Level and then increase until proper

holding torque has been achieved.

08.01

DC Brake Time during Start-up

Unit: 0.1

Settings

0.0 to 60.0 sec

Factory Setting: 0.0

This parameter determines the duration of the DC Brake current after a RUN command. When

the time has elapsed, the AC motor drive will start accelerating from the Minimum Frequency

(Pr.01.05).

08.02

DC Brake Time during Stopping

Unit: 0.1

Settings

0.0 to 60.0 sec

Factory Setting: 0.0

This parameter determines the duration of the DC Brake current during stopping. If stopping

with DC Brake is desired, Pr.02.02 Stop Method must be set to 0 or 2 for Ramp to Stop.
