DRV8308 : Problem in using ADVANCE feature

Other Parts Discussed in Thread: DRV8308, DRV8308EVM

Hi,

I am using DRV8308 EVM board to run a motor. Motor runs fine in CW direction with default settings and value of ADVANCE reg=157. With this setting motor is not rotating properly in CCW direction. It rotates for few seconds with high current ,vibrations and noise then stops. If I change value of DELAY from 0 to 1, with ADVANCE reg=157, motor rotates in CCW but in CW direction motor rotates for few seconds with high current ,vibrations and noise then stops which is reverse of previous case when DELAY=0. All other settings are default settings, I have not changed any other settings. Please suggest what might be issue for this behavior. I need single setting where motor works efficiently in CW and CCW direction.

regards,

Pooja Mishra
