Yes, it pretty much has to be with the AD chips, or at least
that makes the most sense. It would make the hookup about as
simple as an encoder.

Rob,
Let me clarify a bit. The application is for a coil
winder on a non round form. The form will be directly
attached to the motor shaft. I need to velocity
modulate the speed of the A axis as it goes around
corners in order to help maintain constant tension.

There is no difference except the velocity. Steppers s
My machine is set to to amax. speed of 4800 mm/min (~ 190 inch/min) and
an acceleration of 9600 mm/min.
But somehow, during milling I reach only speeds of up to 600 mm/min when
doing small steps in the program.
The thing is controlled with an older PC I still had standing in a

I wonder if this is the same problem Fred is having? I have never used
steppers so I am clueless (well okay, more than normal).

Hi,
I am confused by an odd stepper problem which I can't understand. The
stepper affected is the one driving my rotary axis and the problem
is
that it won't go fast enough... To explain - if I issue a G1 command
in
MDI, I am limited to a F20 speed as, beyond that, the stepp

Watching this video brought some questions to mind.

How do they get the work piece to move in the Z direction while turning?
The work piece must be clamped at all times in order to maintain the
part index. The bar stock must have a fai

Hi Jon,
Would you put the excitation source on the board also?
D
BTW - It is my understanding that resolvers will stand insanely high
rpm. I've heard figures of 60K rpm.

Gentlemen,
Jon, I don't know the level of demand for a resolver board. Would
this be a ppmc card or a separate module? I would like to have the
option in the ppmc set. If the price isn't too high I would buy five
to start.
There are still quite a few machines in service that have resolvers.
