Asynchronous Motor Setup
5.5.1
5.5.1.1 Setting Up Asynchronous Motor
1.
Enter the following motor data in the listed order. Find the information on the motor nameplate.
a.
Parameter 1-20 Motor Power.
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.
2. For optimum performance in VVC+ mode, extra motor data is required to set up the following parameters. The data is found in
the motor datasheet (this data is typically not available on the motor nameplate).
a.
Parameter 1-30 Stator Resistance (Rs).
b.
Parameter 1-31 Rotor Resistance (Rr).
c.
Parameter 1-33 Stator Leakage Reactance (X1).
d.
Parameter 1-35 Main Reactance (Xh).
3. Run a complete AMA using parameter 1-29 Automatic Motor Adaption (AMA) [1] Enable Complete AMA or enter the parameters
manually.
Application-specific Adjustment When Running VVC+
5.5.1.2
VVC+ is the most robust control mode. In most situations, it provides optimum performance without further adjustments. Run a
complete AMA for best performance.
PM Motor Set-up in VVC+
5.5.2
5.5.2.1 Initial Programming Steps
1.
Set parameter 1-10 Motor Construction to the following options to activate PM motor operation:
a.
[1] PM, non salient SPM
b.
[3] PM, salient IPM
2. Select [0] Open Loop in parameter 1-00 Configuration Mode.
