p29041[1] is the scaling of analog input 2.
For example, if p29041[1] is 100%, the relationship between torque limit value and analog
input is shown as follows:
In this case, analog input of 5 V corresponds to 50% of rated torque and 10 V corresponds to
100% of rated torque.
Torque limit reached (TLR)
When the generated torque has nearly (internal hysteresis) reached the value of the positive
torque limit, negative torque limit or analog torque limit, the signal TLR is output.
