hey guys just a update and a few more questions
so I managed to get the encoder mounted on my spindle and working fine.
the vfd works in closed loop control now and I get quite nice power

Awesome thanks andy.
I guess everyone is just busy.
Been mucking around with some hal stuff.

at almost zero rpm its great actually.

An inline resistor will only work if the current is

Question on that.
My vfd encoder card reads encoder pulses at above 7v and under 5v I think.
My encoder I bought from a company in China which made it for me. It can
do 10k rpm. And accepts 5-24v input. Output just corresponds to whatever
the input value is. So maybe one solution is drop the

I am not PCW, but I would be nervous about 12V with an absolute max of 12.
Maybe you can use one of the tiny buck-converters from eBay to supply
the encoder with 5V (or 8V) from
awesome andy
just checked and the output is 12v
but I also saw that the input can be anywhere from 5-24 v and I think the
output coresponds to the input voltage
thanks
so Peter
if manual says I can run up to 13v do you think I will be fine?
I saw mention of a 5v control voltage needed? where
There are ways of matching data signal voltages between disparate components.
Here's a patent on one way to do it, likely it's the basis for various
commercial products. https://patents.google.com/patent/US7023242

Using arcane knowledge (ie, how Mesa manuals are named, and how to
google for them) I found the manual.

Hey gene and peter.
Well that's good to know that the ency card only supports 5v. So that's a
no show. All good I'll use them for something else I guess.
So gene.
First off my encoder has a b Z push pull single ended outputs.
Looks like your solution is the plan.
I have a spindle sensor

Hey guys
looking for info on how to wire up a mesa ency encoder card to my vfd.
I have a encoder card that outputs 12v to the encoder that I have (which is
also a 12 v encoder) but would like to split the encoder pulses off to my
7i77 as well as back to schiender altivar 71 vfd.
the vfd does
