The software uses the following model to estimate the speed of the motor. If both the internal and external field controllers are disabled, for example
when a separately supplied field is used, then the flux feedback is assumed to be 100 %.
Where:
Pr 5.04 = estimated speed
Pr 5.53 = back emf
Pr 5.08 = base speed
Pr 5.09 = rated voltage
Pr 5.07 = motor rated current
Pr 5.61 = armature resistance
Pr 5.54 = flux feedback
The voltage measured at the L1, L2 and L3 terminals.
The average measured DC output voltage seen across the motor, as read from the Machine feedback terminals (MA1 and MA2).
The rated current should be set at the motor nameplate value for rated current. The value of this parameter is used in the following:
