Nothing special that I saw. It is a rotary knife type machine with a
driven C axis for the knife rotation. I will attempt to use the old CAM
software. It does generate some G code that I might have to convert
somehow.
The trick come in the pressure and cutting speed and the angle of the
cutting tool edge. The current tool table could be used as is.
The machine has a tilting table and a heap of hydraulics that makes it
complicated.

Remember that CAM for glass cutting is very special and I don't know of
any
CAM packages that can handle glass.
It's gonna bite you're a$$.

The Servopack number is SGDB-03VDY1 like I mentioned below The motors
are
AC servos - USAGED-30V22 and USAGED-05V22K
The machine is a CNC glass cutter that has a horde of pneumatic and
hydraulic functions. The model is an Intermac Fox 3700 I would attempot
to
just replace the pc and control software if I could lay my hands on a
manual
or wiring diagrams. There are several sub controllers or custom plc's
that
makes it impossible.

Yaskawa has been making motors and drives for a long time, and have
made a lot of different kinds, using all manor of controls. Your
going
to have to give us more information for us to give you a
recommendation.
But on the surface I would have to suggest, if there isn't anything
wrong with the motors or drives keep them.
Mesa makes hardware that can work with what ever you have, but you
need
to figure out what you have before choosing the right control
hardware.
Most old Dos controllers I'm familiar with are just software step
generators, and as such can usually be replaced by Linuxcnc with a
minimum of hardware (most just using a parallel port or 2).

Hi All
I have been asked to upgrade a machine that has a very old control
system still running on DOS. It is fitted with Yaskawa SGDB-03VDY1
drives. I cannot seem to find reference to that extract number. There
are two 2.9Kw motors and one 0.45Kw. They all have incremental
encoders.
From the documentation that I could find I could not see how to drive
these things. It looks like a communications protocol that they use.
I have to decide how to go about retrofitting this machine. Do I keep
the motors (they are still very good) and keep the drives (dont know
how to drive). Does Mesa have a solution to drive these?
Or do I dump the drives and use another set of drives? What will I use
or, Do I dump the lot and start fresh. What will I use in the place of
Yaskawa?
Has anyone on the forum used these with reasonable success?
I would like to go 7i80 so that I can fit an industrial panel mount pc
with touch screen.
Any thought from the wise ones?
