[IONI PRO] dead band

Is there a way to configure a “dead band” on a position control drive ?
I mean : if the position reported by the sensor is close enough to the setpoint (range TBD), then the (stepper) motor shall stay in place and not try to get closer to the goal.

Hi Marc

IONI doesn’t have this kind of feature.

Kind regards, Esa

:hushed:
That’s quite detrimental when the mechanics is a little loose (that’s our case, needless to say) : the actuator oscillates back and forth, causing unnecessary wear (even if the position stays in an acceptable range around the targeted point).
:bulb:
What about implementing this feature in customized (or public) firmware ?

Hi Marc

This kind of feature is handled on the controller side, not the drive side. Also, it’s usually assumed that the mechanics have as little play as possible.

Our focus is currently on our Simucube products, and we don’t have any plans on updating IONI firmware.

Kind regards, Esa

Is there a way to stop the stepper motor without switching the current off ?

I guess you could enable/disable the drive as needed either via the IO pins or the SimpleMotion commands, whichever you are using.
