Delta Electronics VFD-EL manual DC Brake Time, 08.00, 08.01, 08.02, 08.03

			Chapter 4 Parameters
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.
