Unable to run PMSM Closed Loop Motor Control Example

Hello ,

I am trying to run PMSM Closed Loop Control Example from S32 example, on S32K144 EVB and DEVKit MotorGD.

After building and downloading the code, on S32K144EVB I see Green LED is glowing. When I press SW2 or SW3 it tries to spin the motor during the LED flashes and motor stops spinning for a while then starts moving back and forth with screechy sound  .The LED turn green to blue. Could not find what could be the reason.

 I am able to load and run all other examples successfully(BLDC open/closed and PMSM open loop)

 I have attached a picture of my setup

I also tried the suggestions given to a similar post ( i took out the J8 jumper and the J9 10 11 are in  1-2 position. R 72 is also set to counterclock max.)

 Can anyone suggest how to make it run . Thank you

Hello and thank you for contacting us.

1) Do you use original motor or your own motor?

2) Can you tell me what is the project name and what is the version? You can find it in release notes. 

3) Could you make a screenshot of fault variables in FreeMASTER as shown below? You can find it in FM project three > Faults and Trips)
