lim 4-20mA Motoric torque will increase the output current
to max torque limit 20mA (set in 4-16 Torque
Limit Motor Mode).
Generative torque will decrease the output to
torque limit Generator Mode (set in
4-17 Torque Limit Generator Mode)
Ex: 4-16 Torque Limit Motor Mode: 200% and
4-17 Torque Limit Generator Mode: 200%. 20mA
