Simple Motion Control question

[junkerjorg]

I am looking to use an encoder type motor to drive a set of rollers to a precise, repeatable spot which will allow a cutter to cut sheets to an operator specified length. I plan to use a compactlogix PLC. Any suggestions on motor and PLC interface? I was thinking a high speed counter card would be sufficient?

Kinetix 300..?

If there is any possibility of slippage between the drive motor and the material, you may want to consider an auxiliary encoder for a feed to length application.

Is this a feed to length, stop and cut operation, or a flying shear?

What is the approximate power requirement of the driven equipment?

For similar applications, I have had success with SEW brand, mostly using their servo motors and a Movidrive VSD controller. It has a resolver built in for positioning, and can also take an extra encoder for increased accuracy (I never needed to use this) and has quite a bit of built in functionality. It would then communicate with your PLC using Devicenet or Ethernet IP. You will not need a high speed card with this option.
