Output value will be zero at low speeds when the current injection is active (r1751.5 = 1).
Note:
The electrical torque is not the same as the mechanical torque, which can be measured on the shaft. Due to
windage and friction a part of the electrical torque is lost in the motor.
r0032 CO: Act. filtered power Min: -
Datatype: Float Unit: - Def: -
P-Group: CONTROL Max: -
Displays motor power (power output at the motor shaft).
