That is using step and direction if it is running the Chinese
control software. I took that all out of my laser and have been
putting in Mach4 with Ethercat :) . We are working on trying to
talk to the Raycus fiber generator now ... That is NO fun to try
and get support from them

That mostly makes sense, I have a Senfeng
4KW laser that has a mixture Yaskawa and Delt drives on it. I
will do some more reading on Ethercat.

Thank-you!

Hi Guys,
EtherCat is basically a distributed motion controller. So
picture an ESS that? is in the drives as well as in the IO
blocks . Its sort of like a Modbus setup but is all in
realtime. You can mix and match hardware in an Ethercat
system. So you can have drives from Yaskawa , Elmo, Omron ,
Delta , Leadshine and so on all on the same network. The
drives could power Steppers or servos (the system has no idea
what one it is..) You can also use IO from in the drives OR
add IO modules as well. The Ethernet cable just goes from
drive to drive and IO to IO. With the Kingstar / Mahc4 setup
you can also to ABS encoders so you do not need to home the
machine when you start it. This is REALLY cools because you
don't need to have home switches or any of that other
hardware. You can also read as much data about the drive as
you would like. So you can see what current the motor is using
for example .
?
Now you can do this without the Kingstar software and add a
hardware master like the board Vital systems has. This is a
little more limiting but is much more flexible as to what PC
it will work with. This is not the be all end all but it is
the best way to make a high end system. It is the future...
Well it really is here and the prices have been dropping like
crazy.
?
Okay I think that made more confusion than it helped ;)

Thanks
Brian

No
problem, o1bigtenor. I want to know more about
Ethercat also. Go ahead with the discussion!
Does
an Ethercat drive network directly to the PC,
or is there still a motion control
interface/card?
?
My phrase is 'what I know I can
write on paper with big block letters and there is
still plenty of room?
inside the thimble, after
inserting the paper, for my finger' - - - - which
is to say - - precious little.?
AIUI its a ethernet
modification - - - to speed communications between
devices, specifically?
- - again, AIUI, for drives to
controls. There is a master info source at:?
my search engine (duckduckgo)
included this with that address:?
The?EtherCAT?technology overcomes the
system limitations of other Ethernet solutions:
The Ethernet packet is no longer received, then
interpreted and copied as process data at every
connection. Instead, the Ethernet frame is
processed on the fly.
So
- - - it would seem that the value is in high
speed connections.?
I'm
not sure at what level ethercat comes into its
own - - - haven't been able to?
find
anything like 'a noobs guide to ethercat' . As
usual one is expected to be?
at
least sorta of a master form the get go - - - -
docs are so tedious to write?
is
what needs to be remembered (NOT - - -imo!). So
the whole seems like it?
could
be useful - - - but exactly how - - - well - - -
that's why I was asking for?
(One
more technology to master)
From
the still quite befogged mind of?
