Hi Nimesh,

What do you have jumper J8 configured as?

the results you are getting may be unexpected due to what you have configured on your board.

Hi,

The AREF jumper position on 1:2 previously, in both configuration the the negative half current is not getting sense can you explain me why it is happening please find the below attached waveform with both configurations. 

Hi Nimesh,

measured the Current on ISENA

Are you measuring voltage or current? I noticed the scale on the scope is voltage and not current?

Can you point out on your schematic where you are taking these measurements? Can you send waveforms from ISENA, ISENB, ISENC, and the phase current?

HI, 

I measuring the voltage on ISENA pin using voltage probe.

Can you please send waveforms from ISENA, ISENB, ISENC, and the phase current so I can better direct you to a resolution?

Hi Nimesh, 

Have you solved your issue or are you able to provide the requested waveforms?
