(1) Torque limit level
1) When Pr. 810 = 0
In the factory setting, limit is made on all
quadrants on the Pr. 22 torque limit level.
When you want to set the level on a quadrant
basis, change the corresponding parameter
value.

Setting
Set the torque limit level in % for speed control or position control so that the
output torque does not exceed the predetermined value. (0 to 400%)
When Pr. 810 = 0,
150
The setting increments of Pr. 22 "torque limit level" and Pr. 812 to Pr. 817
(torque limit level) and the speed from the communication can be changed.
0: Torque limit 0.1% increments;
Speed from the communication 1r/min increments
1: Torque limit 0.1% increments;
0
Speed from the communication 0.1r/min increments
10: Torque limit 0.01% increments;
Speed from the communication 1r/min increments
11: Torque limit 0.01% increments;
Speed from the communication 0.1r/min increments
Set the torque limit level in % for regeneration. (0 to 400%)
9999 Valid for regeneration when Pr. 810 = 0.
9999: Restricted to the Pr. 22 value.
Set the torque limit level in % for 3rd quadrant. (0 to 400%)
9999 Valid for reverse rotation driving when Pr. 810 = 0.
9999: Restricted to the Pr. 22 value.
Set the torque limit level in % for 4th quadrant. (0 to 400%)
9999 Valid for reverse rotation regeneration when Pr. 810 = 0.
9999: Restricted to the Pr. 22 value.
When the TL signal is on, the Pr. 815 value is a torque limit value regardless
of Pr. 810.
9999 Set the torque limit level in % for all operations. (0 to 400%)
Valid when the TL terminal (torque limit selection) input is provided.
9999: According to the Pr. 22 value.
Set the torque limit value for acceleration.
9999
9999: Same torque limit as at constant speed
Set the torque limit value for deceleration.
9999
9999: Same torque limit as at constant speed
2) When Pr. 810 = 1
With the upper limit of torque limit as set in Pr. 22, the analog
input from the terminal 3 input is used as the torque limit
value within the Pr. 22 setting range. When the torque limit
function is selected in the regenerative mode with the
terminal 1 selected, the input from the terminal 1 is used as
the torque limit on the regenerative side. (Pr. 868 = 2)
