Sensorless FOControl of 3-Phase Induction Motors VphaseC;

Good day

Please help me with problem with Level 2A – Testing the Phase Voltage module.

When trying to check VphaseC variable it shows 0, therefore VphaseA, VphaseB are working. It is like on attached picture

or when changing to DlogCh4 = (int16)_IQtoIQ15(volt1.VphaseC); for observation of a VphaseC through DlogCh I got this like on picture , therefore other VphaseA and VphaseB work perfectly.

Incoming signals to volt macro module - MfuncV1, MfuncV2, MfuncV3, and DS bus voltage are ok.

Hello

Thank you for your answer.

svgen_dq1.Tc and pwm1.MfuncC3 working ok. Here is attached picture.On dlog window DualTimeA-0 signal is the same like DualTimeB-0. What problem maybe? Code is from controlsuite

Thank you
