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

P-Group: CONTROL
Displays motor power (power output at the motor shaft).
Motor
Dependency:
Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).
r0035[3]

CO: Act. motor temperature

P-Group: MOTOR
Displays measured motor temperature.
