Hi

Can one implement stall detection on the L6474?

Thanks

Andre

Hi Andre

Unfortunately it is not possible to implement this feature using the L6474.

Enrico, do you know how to impliment anti resonace control in a stepper driver ? Some stepper drives have it.

Damping the resonances of the stepper motors through an electronic control (electronic damping) can be very complex.

First of all you need a feedback which identify the resonance condition (usually an high resolution encoder) and than you need to drive the motor coils in order to generate a proper damping stimulus.

In general the resonances are dampen using mechanical systems shifting the oscillation frequency out of the operative range.
