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: | - |

|
| Max: | - |
Displays motor power (power output at the motor shaft).

r0032[hp] = 0.75 ⋅ r0032[kW]
Dependency:
Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).
