Delta Electronics VFD-VL manual 07-23, 07-24, 07-25, 07-26, 07-27

Chapter 4 Parameters
07-23	Low Torque Offset		Unit: 0.1
Control	SVC	FOCPG TQCPG FOCPM	Factory Setting: 10.0
mode
	Settings	0.0 to 100.0%

When it is set to 3, the source of torque offset will decide to Pr.07-21, Pr.07-22 and Pr.07-23 by the multi-function input terminals setting (19, 20 or 21). The motor rated torque is 100%.

07-24	Forward Motor Torque Limit		Unit: 1
07-25	Forward Regenerative Torque Limit		Unit: 1
07-26	Reverse Motor Torque Limit		Unit: 1
07-27	Reverse Regenerative Torque Limit		Unit: 1
Control	FOCPG TQCPG FOCPM		Factory Setting: 200
mode
	Settings	0 to 500%

The motor rated torque is 100%. The settings for Pr.07-24 to Pr.07-27 will compare with Pr.03- 00=5, 6, 7, 8. The minimum of the comparison result will be torque limit.
