Matsuura Mc 500v2 retrofit.

23 Feb 2016 16:54 #70526 by skunkworks
We purchased this machine a couple years ago. It is an early 80's model with a mx1 control. The servo and spindle drives work just fine so we are planning on re-using everything that we can.

Going with mesa (of course)

We lucked out an all the axis encoders are 5v differential (some had 12v)

The setup is going to be
computer -> Ethernet -> 7i80 -> 7i48
                          V  ->  24 port opto22 board
                          V  ->  7i44 -> 7i73
                                   V  -> 7i69 -> 2x 24 port opto22 boards

That will give me
-6 axis of analog out/differential encoders
-72 i/o
-panel interface MPG's and i/o

Currently We just started and only have worked on getting a basic spindle encoder installed. It doesn't have one and we would like to be able to rigid tap.

We are using gear teeth sensors to do the quadature+index (they are not mounted yet)
This is a 69 tooth gear.

This will be slow going as I will only be able to work on it a few hours a week.

Nice gear install.

Are you using a 7I80HD-16?

Which Opto22 cards do you use?

I would like to hear more about the opto 22 setup as well. Do you need the pci ac5 card? They are always pretty expensive on ebay,

these style boards are a direct plugin to the mesa 50 pin connector.

(really handy)

we used a combination of what we had on the K&T

ok, I read this

and thought I needed the ac5 board.

The spacing needs tweeking - but a nice signal.

Better. The bracket for the index sensor is made and ready to be mounted too.. (that was at 6000rpm)

Looks serviceable, well done!

hooked the spindle encoder into the 7i48. seems to count and sees the index.
