Hall Effect for Spindle Speed Feedback
« on: September 05, 2017, 06:46:21 PM »
    Can a Hall Effect be used as Spindle Speed Feedback ? I have a LARGE ! VMC that has high and low range speed through belts, but had a Hall sensor from the OEM .
For Spindle speed feed back. I have Mach4 , everthing works, but spindle has no reference to Mach4 for accurate RPM.

Hall Effect is the method of detection. Typically those sensors have some standard transistor output sinking or sourcing. Industrial stuff usually works over a range of 10 to 30 vdc, while most hobby boards use  5 vdc so that may be an issue, or not.

 Gary , this is an 93 model Fadal , it used 5v for the hall sensors . I'm just not sure how to hook it up to the board for feed back. Or  could I just put a prox in the halls
place and use the same magnet?
