08.00

DC Brake Current Level

Settings
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

Settings
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

Settings
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.
08.03

Start-Point for DC Brake

Settings
This parameter determines the frequency when DC Brake will begin during deceleration.
