Torque control operation

4.2.3Setting procedure

Perform secure wiring. (Refer to page 7.)

Set the PLG. (Refer to page 12.)

Set the motor to be used. (Refer to page 19.) Refer to page 19 if the motor is one rank lower.

It is not necessary to set the PLG when using the dedicated motor (SF- V5R).

Set any of "1 (torque control), 2 (speed-torque switchover), 5 (position-torque switchover)" in Pr. 800 "control system selection" to make torque control valid. (Refer to page 53.)

Set the torque command. (Refer to page 38.)

Set the speed restriction value. (Refer to page 39.)

Test run (Refer to page 22.)

As required

•Perform online auto tuning.

(if torque control accuracy needs to be improved) (Refer to page 46.)

Set torque restriction during speed control.

4.2.4Torque command right selection

Using Pr. 804 "torque command right selection", set the method by which the torque command will be given. The torque command is factory set to the torque command connected across terminals 3-5.

(This parameter is an extended function parameter. Set "1" in Pr.160 "extended function selecion".)

Pr. 804 Setting		Description
0	Torque command connected across terminals 3-5 (analog)
