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
