This is quite funny. Thanks for sharing your story.

Hello,
After reviewing everyones input, for which I am extremely appreciative, I came
to the conclusion that if the spindle feedback was an encoder, it was a style
which I could not read. Not wanting to replace the unit, for fears of having
to fab up yet another adapter, I took a chance and r

I think you can set the ref freq with a cap or resistor. If the
freq is lower, then the tracking and

Hi Jon,
Those are hot chips... don't know how many resolvers there are out
that will handle the reference freq tho ... but not many apps will
push the rps spec. ;-)

I've seen Heidenhain encoders that have 5 pairs, they
have 4 lines for power. Some companies use extra
return (ground) lines. There is also the possibility
of an extra track like on brushless servo motors,
which can have a "hall track"
Or like John said, it could be an absolute encoder,
although

Hello Richard,
I have a Hardinge HNC that I am converting. Your description doesn't
match mine very well so I'll assume you have a different model, but I
did find that my spindle pulse generator had terminal pairs for both the
LED and the "amp" (+12 V and GND on both) along with the pulse and the

Why would a resolver have 5 pairs of wires? I would think 3
pairs would suffice for any flavor of resolver. The only thing
I can think of that needs 5 pairs would be
First see if you can find any markings indicating a manufacturer, if so search
for them on the web and look for a similar encoder, they might have the wiring
published online. If that doesn't work, I would ohm between each color and
black to make sure none are tied together, if the are, that's
If this is an older Hardinge like a HNC or CHNC this may be a resolver rather
than an encoder.
