torque limit
selection
TL1
The internal torque limit 2 (parameter No. PC14) becomes valid by turning
TL1 on.
The forward torque limit (parameter No. PA11) and the reverse torque
limit (parameter No. PA12) are always valid.
The smallest torque limit among the valid forward and reverse torque
limits is the actual torque limit value.
