[149] Torque %
lim 4-20mA
Analogue output at zero torque = 12mA.
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
= 200% Motoric and 4mA = 200% Generatoric.
