HV Motor Control and PFC Developer's Kit - Position Control

Hi,

I am trying to run the "HVPM_Sensored_Servo" example that came with High Voltage Motor Control and PFC Developer's Kit ( TMDSHVMTRPFCKIT ).

When I run the project in build level 5, the motor "tries" to get to the positions listed in posArray, but is very unstable. After roughly pausing at 2-3 positions, it becomes very unstable and begins to vibrate and eventually stop. Then I need to reset the controller to make it work again.

Do I need to change any parameters or PI loop gains? If so, any recommended values to start with will be very helpful. I am using the motor that came with the kit (ESTUN EMJ-04APB22).

Thanks,
Tamil
