Hi,
I'm using DRV8308-EVM to evaluate scroll compressor. I observed that there is significant SPEED drop when there is small change in load. Hall Sensor: 110.2Hz to 103.5Hz. i.e., from Motor speed 1,653 rpm to 1,552.5 rpm
I have attached SPI register settings. Please let me know is there any configuration parameter is to be tuned?
Also, I have attached scope capture of a) Motor phase winding current (CH #1, Yellow) and b) Hall Sensors input (Ch #3, Pink).
Early support on this is highly appreciated as this is issue needs to be resolved ASAP.
