Group 8: Special Parameters
08.00 DC Brake Current Level Unit: 1
Settings 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.
08.03 Start-Point for DC Brake Unit: 0.01
Settings 0.00 to 600.0Hz Factory Setting: 0.00
This parameter determines the frequency when DC Brake will begin during deceleration.
