Delta Electronics VFD-VE Series manual 00-09, Energy Saving Gain Unit, Factory setting 100%, 00-10

Chapter 4 Parameters

00-09	Energy Saving Gain		Unit: 1
Control	FOCPG		Factory setting: 100%
mode
	Settings	10~1000 %

When Pr.00-19 is set to1, this parameter can be used for energy saving. The setting should be decreased when the energy saving is not well. When the motor is vibrated, the setting should be increased.

00-10	Control Method
Control	VF	VFPG	SVC FOCPG TQRPG	Factory setting: 0
mode
	Settings	0	V/f control
		1	V/f + Encoder (VFPG)
		2	Sensorless vector control (SVC)
		3	FOC vector control + Encoder (FOCPG)
		4	Torque control + Encoder (TQRPG)

This parameter determines the control method of the AC motor drive:

Setting 0: user can design V/f ratio by requirement and control multiple motors simultaneously.

Setting 1: User can use PG card with Encoder to do close-loop speed control.

Setting 2: To have optimal control characteristic by auto-tuning.

Setting 3: To increase torque and control speed precisely. (1:1000)

Setting 4: To increase accuracy for torque control.

00-11V/f Curve Selection

Control	VF	VFPG		Factory setting: 0
mode
	Settings	0	V/f curve determined by group 01
		1	1.5 power curve
		2	Square curve

When it is set to 0, the V/f curve setting for the motor 1 is according to Pr.01-01~Pr.01-08 and Pr. 01-35~01-42 are for the motor 2.

When setting to 1 or 2, the settings of the 2nd voltage/frequency and the 3rd voltage/frequency are invalid.
