Group 8: Special Parameters

08 - 00 DC Brake Current Level

Settings

00 to 100%

Unit: 1

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

Settings

0.0 to 60.0 sec

Unit: 0.1

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

Settings

0.0 to 60.0 sec

Unit: 0.1

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

Settings

0.00 to 400.00Hz

Unit: 0.01

Factory Setting: 0.00

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