Add a positive voltage to TL. The negative voltage is limited to zero.
If P2.57 is 1, the torque limit is always the TL value.
(2) In case of torque control
The forward rotation torque limit and reverse rotation torque limit are followed.
(3) Torque limit for controlled stop action (under position or speed control) (If P2.57 is 0)
