Add a positive voltage to TL. The negative voltage is limited to zero.
A negative setting is limited to zero.
If PA2_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 PA2_57 is 0)
