Other Parts Discussed in Thread: DRV10866EVM, DRV10866

Hi

My customer is using DRV10866EVM.
He uses motor whose pole pairs is 4.
He sets FGS=1.

Could you let me know how to calculate max RPM value?

He has a issue.
When FG frequency exceeds 700Hz, Motor stops.
And then, When it's done for a while, Motor moves. But motor stops immediately.

Best regards

Hi Shimizu

DRV10866 will have a MAX speed limit to drive. The limit should be smaller than 700 Hz. We need to check the limit level later. So the motor you have may not fit for the driver.

Best regards,

Hi Wilson

I understood that Max FG frequency of DRV10866 is about 700Hz.
Could you release new datasheet which is wrote about max FG frequency?

Thanks
Shimizu
