8.4 Torque control (operating mode 1)
This operating mode does not control the torque in the classic way since the speed control
continues to work to control the speed limit. The torque reference will be the Pr7 main
reference. To set up the torque control, you must first adjust the speed control in order to
establish a stable system and then set Pr31 = 1 in order to program the operating mode by
setting the default values with the command b 99.11. Set Pr2 = 1000 (10 V = 100.0 % of the
torque), b40.0 = 0, b40.12 = 0, b40.2 = 1 to enable the reserved reference and Pr100 to limit
the maximum speed of the motor.
