TMS320F28335: TMDSHVMTRPFCKIT

Part Number: TMS320F28335
Other Parts Discussed in Thread: CONTROLSUITE

Dear TI support,

I have TMDSHVMTRPFCKIT motor control development kit using TMS320F28335. I need to implement FOC of AC induction motor.

I have Code Composer 11.2.0. I downloaded the following project from ControlSuite: HVMotorCtrl+PfcKit_v2.1\HVACI_Sensorless_2833x.

Project compiles fine. I am following instructions detailed in Sensorless FOC of ACI_2833x.pdf document.

Compilation is Level1. I am doing the SVGEN_MACRO Test. For some reason, the graphs for SVGEN duty cycle outputs are not correct. They look very different to the ones shown on page 22 of document.

I tried to adjust the following with no success: SpeeRef, VdTesting, VqTesting

The Y-axis scale is much larger. I could not reduced its range. Please see image below

I appreciate your help

Felix
