			Chapter 4 Parameters
07-20	Torque Command		Unit: 0.1
Control	TQRPG		Factory Setting: 0.0
mode
	Settings	-100.0 to 100.0%
		(Pr. 07-22 setting=100%)

This parameter is torque command. When Pr.07-22 is 250% and Pr.07-20 is 100%, the actual torque command = 250%X100% X motor rated torque.

07-21	Torque Command Source
				Factory Setting: 0
Control	TQRPG			Factory Setting: 0
mode
	Settings	0	Digital keypad
		1	RS485 serial communication (RJ-11)
		2	Analog signal (Pr.03-00)

This parameter is torque command source and the torque command is in Pr.07-20.

07-22	Maximum Torque Command		Unit: 1
Control	TQRPG		Factory Setting: 100
mode
	Settings	0 to 500%

This parameter is for the max. torque command (motor rated torque is 100%).

07-23	Filter Time of Torque Command		Unit: 0.001
Control	TQRPG		Factory Setting: 0.000
mode
	Settings	0.000 to 1.000 sec

When the setting is too long, the control will be stable but the control response will be delay. When the setting is too short, the response will be quickly but the control maybe unstable. User can adjust the setting by the control and response situation.

Control	TQRPG		Factory Setting: 0
mode
	Settings	0	By Pr.07-25 and Pr.07-26
		1	Frequency command source (Pr.00-20)
