Group 8: Special Parameters
08 - 00
DC Brake Current Level
Unit: 1
Settings
00 to 100%
Factory Setting: 00
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
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 00 or 02 for RAMP stop.
08 - 03
Start-Point for DC Brake
Unit: 0.01
Settings
0.00 to 400.00Hz
Factory Setting: 0.00
This parameter determines the frequency when DC Brake will begin during deceleration.
