(1)Torque restriction level

1)When Pr. 810 = 0

In the factory setting, restriction is made on all quadrants on the Pr. 22 torque restriction level. When you want to set the level on a quadrant basis, change the corresponding parameter value.

2)When Pr. 810 = 1

With the upper limit of torque restriction as set in Pr. 22, the analog input from the No. 3 terminal input is used as the torque restriction value within the Pr. 22 setting range. When the torque restriction function is selected in the regenerative mode with the No. 1 terminal selected, the input from the No. 1 is used as the torque restriction on the regenerative side. (Pr. 868=2)
