Chapter 4 Parameters

This parameter is torque command source and the torque command is in Pr.07-12.

07-14	Maximum Torque Command		Unit: 1
Control	VF	VFPG SVC FOCPG TQCPG FOCPM	Factory Setting: 100
mode
	Settings	0 to 500%
This parameter is for the max. torque command (motor rated torque is 100%).
07-15	Filter Time of Torque Command		Unit: 0.001
Control	TQCPG		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.
