For motor actual current in T30 T40 CoDeSys program, use objects:
C3.StatusDevice_ActualCurrent [o683.1]: This is the motor's actual current/torque in % the motor's rated current/torque.
C3Plus.StatusDevice_MotorCurrent [o670.9]: This is the motor's rated torque in mNm (or force in mN for linear servo motors) AT RATED SPEED.
The motor's rated current/torque is part of the motor file in the Drive Configuration. At higher voltages, 400/480vac, the rated torque can be lower.
