Cheap EtherNet/IP Based Servo Systems

Hey all...

My company is looking to put together sort of a standard product or at least a canned product for doing some simple motion of up to 4 small axis. Nema 23/34 size motors. I've been looking around trying to find a reasonably priced servo system which has some sort of Ethernet based communication protocol, preferably EtherNet/IP. Other than the AB Kinetix line, does anyone else have any recommendations for an inexpensive system?

NOTE: The motions will be index time actions, they do not need to be coordinated axis.

You might look into Lenze Highline or SEW Eurodrive.

Check out omron. You could probably get a rep to tell you exactly what you need. I've seen some of their new stuff, it's pretty good.

We've started using these:

They run on 48V DC, integrated drive and motor, on board IO.

Need one of these if you will be changing direction a lot, or high interia:

Does it have to be servo or just closed loop?
Are you using a PLC to control the motion or prefer to have it in the drive?

You can do closed loop with AC and Stepper motors - that will keep costs down. Of course this depends on your accuracy, speed, loads, etc.

If you absolutely need servos I use Emerson EP drives because the drive controls the motion. You can use a PLC with it (talks Ethernet/IP) or just a plug HMI directly to it for control and adjustments. Their interface is really easy to understand and basic motion is all set up- just plug in some numbers and go.

Yaskawa has motion card that plugs into a 1756 rack to control Sigma series servos with AOI's in Logix. Or you could use my preferred method, Logix to an MPiec controller via E/IP.
