[149] Torque %
lim 4-20mA
Analog output at zero torque = 12 mA.
Motoric torque will increase the output
current to max torque limit 20 mA (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%. 20
mA = 200% Motoric and 4 mA = 200%
Generatoric.
