In reply to suresh mukundan11:
- Digital IO pins AMODE, , VA0, VA1, FAULT, FAULTRES, etc. do not have pull up or pull down up it is connected to processor pins witch works on 3.3V
- Digital IO pins ECLKSEL was connected to 5V ( PGA411-Q1 was heating and drawing more current )
--Digital IO pins ECLKSEL was connected to 3.3V ( PGA411-Q1 is not heating and draws less current ) and the waveform is stable
Thanks a lot for your suggestion
plan to do some more test and would keep up updated
- plan to change the exciter voltage VEXT to 15V currently it is working 10V
- Load the resolver coil
