Chapter 4 Parameters
07-05	Start-Point for DC Brake			Unit: 0.01
Control	VF	VFPG	SVC FOCPG	Factory Setting: 0.00
mode
	Settings		0.00 to 120.00Hz

This parameter determines the frequency when DC Brake will begin during deceleration. When the setting is less than start frequency (Pr.01-09), start-point for DC brake will begin from the

min. frequency.
