Gentlemen,
Unfortunately necessity breeds investigation. The Fanuc 11M on my Enshu is
dying. In concert with Fanuc we can find no cause. It is now at the point of
beginning a random board replacement until the culprit is eliminated. This
could be expensive.
The other option is EMC2!! -

If that generated tach signal was sufficient for the amps in the late 70's
would the current technology be able to at least match it?
I have several competing ideas in my head about this. I will list
them in order from least

After review of a previous discussion on the necessary tach signal for the
amp I have questions bouncing around in my head.
If the 11 control is S SLOOO in program execution would that control

The AD650 has bipolar output but not quadrature input so would probably not
be
useful as a bidirectional tachmometer replacement.
A quadrature to direction pulse converter would be a very simple circuit
to make.
The L290 interestingly enough is a sine/cosine

I certainly don't see how you can get bipolar output from this chip, all
