Step 7: Tune the Motor Side Inverter Control
Select the Source of Motor Control Parameter Values
In this procedure, you select the source of motor control parameter settings. These parameters include stator resistance,
leakage inductance, flux current reference, encoderless electrical angle compensation, stator resistance compensation
factor, and slip speed at full load.
1. Navigate to parameter 10:510 [MtrParam C/U Sel].
2. Press the EDIT soft key.
3. Set the value for this parameter to 2 ‘LoadCalcData’.
4. Press the ENTER soft key.
TIP The options for this parameter include the following:
0 ‘Calculated’ – The parameters are set to values that have been calculated from previously entered information. These
values are not based on the results of a Motor ID test.
1 ‘User Entered’ – The parameters are set to values entered by the user. User entered values can be values that were
copied from the Calculated values, if LoadCalcData was selected and no Motor ID test was run. User entered values can
also be the measured test results from a Motor ID test, if LoadCalcData was selected and then a Motor ID test was run.
2 ‘LoadCalcData’ – When this option gets set, it copies the default Calculated values into the parameter as User Entered
values, providing default values to start with before any test has been run. It then sets the value of 10:510 [MtrParam
C/U Sel] to 1 ‘User Entered’, allowing you to adjust the Calculated values. Additionally, when LoadCalcData has been set,
whenever a Motor ID test is run, the motor control parameter values are updated using the results of the test. After the
values are updated using the test results, the value of [MtrParam C/U Sel] is set to 1 ‘User Entered’. This allows User
Entered changes to the test result values.
