Chapter 5 Parameters_VFD-B Series
Revision 10/2005, BE13, SW V4.08 5-83
Group 8: Special Parameters
08 - 00
DC Braking Current Level Unit: 1
Settings 00 to 100% Factory Setting: 00

This parameter sets the level of DC Braking Current output to the motor during start-up and stopping. When
setting DC Braking Current, the Rated Current (Pr.00-01) is regarded as 100%. It is recommended to start
with a low DC Braking Current Level and then increase until proper holding torque has been attained.
08 - 01
DC Braking 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 Braking 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 Braking 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 Braking current during stopping. If stopping with DC
Braking is desired, Pr.02-02 Stop Method must be set to 00 or 02 for RAMP stop.
08 - 03
Start-Point for DC Braking Unit: 0.01
Settings 0.00 to 400.00Hz Factory Setting: 0.00

This parameter determines the frequency when DC Braking will begin during deceleration.
