Select [0] Open Loop in parameter 1-00 Configuration Mode.
If PM speed closed loop is needed, choose flux control mode.
Programming Motor Data
3.2.2.2
When the initial programming steps are completed, the PM motor-related parameters in parameter groups 1-2* Motor Data, parameter
groups 1-3* Adv. Motor Data I, and parameter groups 1-4* Adv. Motor Data II are active.
The information is on the motor nameplate and in the motor datasheet.
1.
Program the following parameters in the listed order:
Parameter 1-24 Motor Current.
¢
Parameter 1-26 Motor Cont. Rated Torque.
¢
Parameter 1-25 Motor Nominal Speed.
¢
Parameter 1-39 Motor Poles.
¢
Parameter 1-40 Back EMF at 1000 RPM.
¢
Parameter 1-42 Motor Cable Length.
¢
2.
Run a complete AMA using parameter 1-29 Automatic Motor Adaption (AMA) and select [1] Enable Complete AMA.
3.
If a complete AMA is not performed successfully, configure the following parameters manually.
a.
Parameter 1-30 Stator Resistance (Rs). Enter phase common stator winding resistance (Rs). If only phase-to-phase data is
available, divide the phase-to-phase value by 2 to achieve the phase value. It is also possible to measure the value with an
ohmmeter, which also takes the resistance of the cable into account. Divide the measured value by 2 and enter the result.
b.
Parameter 1-37 d-axis Inductance (Ld). Enter direct axis inductance of the PM motor. If only phase-to-phase data is
available, divide the phase-to-phase value by 2 to achieve the phase value. It is also possible to measure the value with an
inductance meter, which also takes the inductance of the cable into account. Divide the measured value by 2 and enter the
result.
c.
Parameter 1-38 q-axis Inductance (Lq). This parameter is active only when parameter 1-10 Motor Construction is set to [3]
PM, salient IPM. Enter the quadrature axis inductance of the PM motor. If only phase-to-phase data is available, divide the
phase-to-phase value by 2 to achieve the phase value. It is also possible to measure the value with an inductance meter,
which also takes the inductance of the cable into account. Make 1 rotation of the motor's rotor and find the maximum
phase-to-phase inductance value. Divide the value by 2 and enter the result.
d.
Parameter 1-44 d-axis Inductance Sat. (LdSat). This parameter is active only when parameter 1-10 Motor Construction is set
to [3] PM, salient IPM. This parameter corresponds to the saturation inductance of d-axis. The default value is the value set
in parameter 1-37 d-axis Inductance (Ld). Do not change the default value in most cases. If the motor supplier provides the
saturation curve, enter the d-axis inductance value, which is 100% of the nominal current.
e.
Parameter 1-45 q-axis Inductance Sat. (LqSat). This parameter is active only when parameter 1-10 Motor Construction is
set to [3] PM, salient IPM. This parameter corresponds to the saturation inductance of q-axis. The default value is the value
set in parameter 1-38 q-axis Inductance (Lq). In most cases, do not change the default. If the motor supplier provides the
saturation curve, enter the q-axis inductance value, which is 100% of the nominal current.
Testing Motor Operation
3.2.2.3
1.
Start the motor at low speed (100–200 RPM). If the motor does not run, check installation, general programming, and motor
data.
