			Chapter 4 Parameters
	Pr.29	DC Braking Time during Start-up	Unit: 0.1sec
		Settings 0.0 to 5.0 sec	Factory Setting: 0.0

This parameter determines the duration for the DC Braking Current applied during starting. DC Braking is applied until the Minimum Frequency is reached.

	Pr.30	DC Braking Time during Stopping	Unit: 0.1sec
		Settings 0.0 to 25.0 sec	Factory Setting: 0.0

This parameter determines the duration for the DC Braking voltage to be applied during stopping. If stopping with DC Braking is desired, then Pr.02 must be set to Ramp to Stop (0.0).

	Pr.31	Start-Point for DC Braking	Unit: 0.1sec
		Settings 0.00 to 60.00Hz	Factory Setting: 0.00

This parameter sets the frequency at which the DC Braking will begin during deceleration.

Notes:

1.DC Braking during starting is used for loads that may move before the AC drive starts, such as hoists and cranes. These loads may also be moving in the wrong direction. Under such circumstances, the DC Braking can be used to hold the load in position before applying a forward motion.

2.DC Braking during stopping is used to stop faster than the ramp-to-stop or to hold a stopped load in position. A dynamic brake resistor may be needed in order to stop loads of high inertia.
