Hello,

Im trying to add hall sensor to read spindle rpm. I do see Index window blink as I rotate spindle(port 3 input 4). But I cant get it to show rpm. Debounce set, relays output set, feedback in sync mode set. I send M3 command ("turn on spindle"), but still no effect.
So I see reaction on spindle rotation,but for some reason ,it doesnt calc RPM.

And advice, please?
