Operating Guide
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
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 parame-
ters manually.

5.4.1.2 Application-specific Adjustment When Running VVC+

+
VVC is the most robust control mode. In most situations, it provides optimum performance without further adjustments. Run a
complete AMA for best performance.

5.4.2 PM Motor Set-up in VVC+

5.4.2.1 Initial Programming Steps

Procedure
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.

5.4.2.2 Programming Motor Data

Encoder feedback is not supported for PM motors.
When the initial programming steps are completed, the PM motor-related parameters in parameter groups 1-2* Motor Data, 1-3*
Adv. Motor Data, and 1-4* Adv. Motor Data II are active.
The information is on the motor nameplate and in the motor datasheet.
Program the following parameters in the listed order.
Procedure
1.
Parameter 1-24 Motor Current.
2.
Parameter 1-26 Motor Cont. Rated Torque.
3.
Parameter 1-25 Motor Nominal Speed.
4.
Parameter 1-39 Motor Poles.
5.
Parameter 1-30 Stator Resistance (Rs).
Enter line-to-common stator winding resistance (Rs). If only line-to-line data is available, divide the line-to-line value by 2
to achieve the line-to-common (starpoint) value.
It is also possible to measure the value with an ohmmeter, which also takes the resistance of the cable into account. Di-
vide the measured value by 2 and enter the result.
6.
Parameter 1-37 d-axis Inductance (Ld).
Enter line-to-common direct axis inductance of the PM motor. If only line-to-line data is available, divide the line-to-line
value by 2 to achieve the line-to-common (starpoint) value.
It is also possible to measure the value with an inductance meter, which also takes the inductance of the cable into ac-
count. Divide the measured value by 2 and enter the result.
