5.3.3 Asynchronous Motor Setup

Procedure
When running in flux control principle, or for optimum performance in VVC+ mode, extra motor data is required to set up the fol-
lowing parameters. Find the data in the motor datasheet (this data is typically not available on the motor nameplate). Run a com-
plete automatic motor adaptation (AMA) using parameter 1-29 Automatic Motor Adaptation (AMA)[1] Enable Complete AMA, or enter
the parameters manually. Parameter 1-36 Iron Loss Resistance (Rfe) is always entered manually.
1.
Enter the motor data in parameter 1-20 Motor Power [kW] or parameter 1-21 Motor Power [HP] to parameter 1-25 Motor Nomi-
nal Speed. Enter the data in the following order:
a.
- Parameter 1-20 Motor Power [kW] or Parameter 1-21 Motor Power [HP].
b.
- Parameter 1-22 Motor Voltage.
c.
- Parameter 1-23 Motor Frequency.
- d. Parameter 1-24 Motor Current.
- e.
Parameter 1-25 Motor Nominal Speed.
Motor data information is on the motor nameplate.
2.
Enter parameters for flux control/VVC+ mode:
- a.
Parameter 1-30 Stator Resistance (Rs).
