Description
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)
