Part Number: DRV8711 Hi Team,
DRV8711 drives the stepper motor to generate severe heat. The voltage is 48V. The motor has a peak driving current of 1A, and even after stopping, there is still coil current, causing the motor to sizzle.

Annie
Hi Grzegorz,
Thanks.
Grzegorz Pelikan said: That ringing usually rises with output current. You can try to capture max. amplitude of ringing by setting trigger on BISENP and slowly adjusting it until oscilloscope stops to trigger. If captured max. ringing…
