Hi Murugavel,

The thread "DRV8889-Q1: DRV8889-Q1 stall detection issue" has been locked. Sorry for opening this thread for response.

We got 14HK0407N stepper this week, and the good news is we could detect stall based on this 14HK0407N stepper.

We might choose other motors in other projects. Another question is: For stall detection, is there any recommended standard for motor selection? Phase resistance<10ohm, Phase inductance<10mH?

Thanks,

Alex

Hi Alex,

Thank you very much for closing back with us. Good to hear the stall detection is working with the 14HK0407N stepper and the DRV8889-Q1.

Generally speaking steppers with coil DCR < 10 Ω and Inductance < 5 mH (while up to 8 mH may be ok) are better suited. Other factors that may affect stall detection would be microstep setting, step rate and ramp rate, drive current IFS and VM operating voltage. Thanks.

Regards, Murugavel
