Parameter Description

r0031

CO: Act. filtered torque

 

Min:

mM : Motor torque

Zp : Pole pair number

Ψrd : Rotor flux

LR : Rotor inductance

Lm : Magnetizing inductance

isq : Torque-generating current e : Motor counter EMF

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).
