Torque limit level
(regeneration)
0.1% 9999
0 to 400%
Set the torque limit level for forward rotation
regeneration.
9999 Pr. 22 value is used for limit.
813
Torque limit level (3rd
quadrant)
0.1% 9999
0 to 400% Set the torque limit level for reverse rotation driving.
9999 Pr. 22 value is used for limit.
814
Torque limit level (4th
quadrant)
0.1% 9999
0 to 400%
Set the torque limit level for reverse rotation
regeneration.
9999 Pr. 22 value is used for limit.
815
Torque limit level 2
0.1% 9999
0 to 400%
When the torque limit selection (TL) signal is on, the
Pr. 815 value is a torque limit value regardless of Pr.
810 .
9999 The torque limit set to Pr. 810 is active.
816
Torque limit level during
acceleration
0.1% 9999
0 to 400% Set the torque limit value during acceleration.
9999 Same torque limit as at constant speed
817
Torque limit level during
deceleration
0.1% 9999
0 to 400% Set the torque limit value during deceleration.
9999 Same torque limit as at constant speed
874
OLT level setting
0.1% 150% 0 to 200%
This function can make an inverter trip if the torque
limit is activated to stall the motor. Set the output
torque at which an inverter trip is made in
Pr. 874
