3.4 Asynchronous Motor Setup

Enter the motor data in parameters 1-20/1-21 to 1-25. The
information can be found on the motor nameplate.

3.5 Automatic Motor Adaptation

Automatic motor adaptation (AMA) is a test procedure that
measures the electrical characteristics of the motor to
optimize compatibility between the frequency converter
and the motor.
•
The frequency converter builds a mathematical
model of the motor for regulating output motor
current. The procedure also tests the input phase
balance of electrical power. It compares the
motor characteristics with the data entered in
parameters 1-20 to 1-25.
•
The motor shaft does not turn and no harm is
done to the motor while running the AMA
•
Some motors may be unable to run the complete
version of the test. In that case, select [2] Enable
reduced AMA
•
If an output filter is connected to the motor,
select Enable reduced AMA
•
If warnings or alarms occur, see 8 Warnings and
Alarms
•
Run this procedure on a cold motor for best
results
NOTE
The AMA algorithm does not work when using PM motors.

3.6 PM Motor Setup in VVC
CAUTION
Do only use PM motor with fans and pumps.
Initial Programming Steps
1. Activate PM motor operation 1-10 Motor
Construction, select [1) PM, non salient SPM
2. Make sure to set 0-02 Motor Speed Unit to [0] RPM
Programming motor data
After selecting PM motor in 1-10 Motor Construction, the
PM motor-related parameters in parameter groups 1-2*
Motor Data, 1-3* Adv. Motor Data and 1-4* are active.
The information can be found on the motor nameplate
and in the motor data sheet.
Following parameters must be programmed in the listed
order
1. 1-24 Motor Current
2. 1-26 Motor Cont. Rated Torque
3. 1-25 Motor Nominal Speed
4. 1-39 Motor Poles
5. 1-30 Stator Resistance (Rs)
Enter line to common stator winding resistance
(Rs). If only line-line data are available, divide the
line-line value with 2 to achieve the line to
common (starpoint) value.
It is also possible to measure the value with an
ohmmeter, which will also take the resistance of
the cable into account. Divide the measured
value by 2 and enter the result.
6. 1-37 d-axis Inductance (Ld)
Enter line to common direct axis inductance of
the PM motor.
