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?

AIUI its a ethernet modification - - - to speed communications between devices, specifically?

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?

could be useful - - - but exactly how - - - well - - - that's why I was asking for?

info tips.?
