DRV8332: Problems when replacing DRV8312 with DRV8332.

Part Number:DRV8332

I am running InstaSPIN labs with F28054M controller. drv8312 kit_revD

Since I am testing more powerful motors, I need a motor driver can provide 4-6A continuous current output.

After hardware modification, when the motor is holding its position, the current output can easily go up to 5A when I was pushing against it (it was 1.2A with DRV8312 before it lost control and generate 2002 position error).

With this new motor driver DRV8332, it should have capability of running powerful motor faster. but it didn't. It can only run smoothly with slow speed and lost control easily with fast speed that DRV8312 can run.

Any ideas why this's happening? What are the parameters that I need to change when replacing DRV8312 with DRV8332? 

Any parameters that I need to change in USER.H?
