I think Allen-Bradley offers a CNC slot card. I need to run a couple of air cylinders then make a stepper motor make 3 different moves. No rocket science here. Any ideas or some experience with this CNC slot card. In fact, here is a pic of the same machine I built 3 years ago. I did all that indexing with air cylinders and a shaft with index pins. It worked, now the customer wants to build another machine. Seems like a stepper/servo motor and ball screw would be better for positioning

Thanks to all that helped me with the shift register question last week.

Thanks,

That doesn't look like a CNC application to me, just a simple indexing application. I'm not sure what you meant by "CNC slot card"; the ControlLogix has motion control via analog or SERCOS or SSI but it's not CNC-like.

A-B has the Ultra 3000 series servocontrollers that you can connect to with ControlLogix motion or DeviceNet.

If there's only one or two axes of motion (and you're set on A-B) I would start looking at the MicroLogix 1500 and the new Ultra 1500 servo controller. The MicroLogix 1500 can do simple step-and-direction motion control fairly easily.

If you want to use an SLC-class controller, look into AMCI's stepper controller modules. Don't try the old SLC "IMC-110" servo or stepper modules; they were junk when they were new.

I don't know the particulars, but A-B does make a single-axis Hydraulic motion module: 1746-HSRV. You might look at it on their web-site and see if it will do what need.
