Speed Loop tuning of TMS320C2000 Motor development kit

Hi,

  I am working on the TMS320C2000 HV Motor Development kit. I was trying the Build Level 4 when I encountered this problem. I am using the Estun servo-motor which is rated for 220 V. The speed loop operation is unstable when the DC bus voltage is above 130 V. I tried to tune the PI module but was unable to achieve stable operation. Any tips would be highly appreciated.

Thanks,

Sandesh
