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 attained.
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 00 or 02 for RAMP stop.
