DRV8711: Support stepper motor 24HS39 up to 200kHz.

Part Number: DRV8711


Hello TI Support.

I have a DRV8711 and stepper motor 24HS39-3008D (BIPOLAR configuration where torque is 4.0Nm and inductance 3.0mH/1kHz). Power supply is 36V or 48V. 

DRV8711 shall works with 1/32 microsteps and up to 200kHz steps frequency.

I am testing this driver using DRV8711EVM and external steps/dir generator to obtain good acceleration (from 1kHz to 200kHz).

I have a problem with settings because I can obtain only 60kHz and motor stops. What is the correct settings?

Now I have settings like on attachment.24HS39-3008D.pdf
