Torque biases
840 Torque bias selection
The torque bias function is designed to quicken the rise of torque at a motor start. You
can set the then output torque using the parameters or analog signals.

841 Torque bias 1
Set the torque bias values when you chose internal parameter-based torque bias
selection. Assign X42 (torque bias selection 1) and X43 (torque bias selection 2) to the
input terminals.
600 to 1400%
1) Pr. 841 when X42 is on and X43 is off, 2) Pr. 842 when X42 is off and X43 is on, 3)
