Delta Electronics VFD007S23A manual Output Frequency, Group 8 Special Parameters

Chapter 5 ParametersVFD-S Series
Group 8: Special Parameters
8-00	DC Braking Current Level		Unit: 1
	Settings	d0 to d30%	Factory Setting: d0

This parameter determines the level of DC Braking Voltage Level output to the motor during start-up and stopping. When setting DC Braking Voltage, the Maximum Output Voltage (Pr.1-

02)is regarded as 100%. It is recommended to start with a low DC Braking Voltage Level and then increase until proper holding torque has been attained.

8-01	DC Braking Time during Start-up		Unit: 0.1
	Settings	d0.0 to d60.0 sec	Factory Setting: d0.0

This parameter determines the duration of time that the DC Braking Current will be applied to the motor during the AC drive start-up.

8-02	DC Braking Time during Stopping		Unit: 0.1
	Settings	d0.0 to d60.0 sec	Factory Setting: d0.0

This parameter determines the duration of time that the DC braking voltage will be applied to the motor during stopping. If stopping with DC Braking is desired, then Pr.2-02 must be set to RAMP stop (d0).

8-03	Start-Point for DC Braking		Unit: 0.1
	Settings	d0.0 to d400Hz	Factory Setting: d0.0

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