Be a great nano PLC control project + FWD-OFF-REV motor starter. Could count cycles and other thing then too. Maybe a Keyence or other NANO PLC.

OPEN to any positions, first preference is NE Indiana, IN, MI, Midwest, SW, S, West and any U.S. I have extensive background in the electrical / mechanical areas as of Manufacturing / Test / Controls - Instrumentation / SCADA and product engineering work. Extensive hands on project management background. I worked my way up through the ranks being: Multicraft maintenance, A-B-C apprenticeship, Military Radar / Fire Control Equipment Tech, Electrician, Electronics Tech / R&D, MFG Eng. / TEST Eng. / Adv. MFG ENG. Senior Electrical Engineer (controls - instrumentation - HW - SW) Application Engineer / SCADA - HMI - PLC Corp MFG Engineer / Controls Engineer Electrical / Electronics Instructor
Industries I have worked:
Plastics, Automotive, Military, Aerospace, Motors / Gearmotors, PCB's, TESTING I worked my way up through the ranks, having first graduating 3 rd in my class in USA Hawk Missile service school in radar and fire control maintenance and obtaining a rank of E-5 in 2 years. When out of service I completed an A-B-C Multicraft factory maintenance apprenticeship and later became an Electrician and Instrumentation technician / troubleshooter for a
24 / 7 plastics operation.
During the last 3 years of the above I went back to school and obtained 2 associates degrees with HI Honors (3.95 / 4.0) and then taught classes for a year at the college. Near the end of this period I was recruited to GE power supply in Ft. Wayne as an R&D technician. The majority of my almost 10 years at GE, I was a MFG / TEST Equipment Engineer in the Advanced Manufacturing Operation for the GE Motors group for 14 plants. I also took more classes and schools during this period.
The main point I want to make is that I have worked my way up through the ranks from the production floor to being THE Corporate Manufacturing Engineer in a medium size company. I have an in-depth view of many aspects of production and product engineering. Other jobs, see resume, has given me background in several industries and cross-functional areas.
I have extensive INSTRUMENTATION - TEST EQUIPMENT and FACTORY CONTROLS - AUTOMATION background that includes PROJECT MANAGEMENT outside procurement, design, build, commissioning, upgrading and troubleshooting. These range from manual bench top setups to networked SCADA systems. PLC, PC and most often combo SCADA systems using PLC stations w/ SCADA and PC for HMI - MMI, product tracking, test result, SPC and other data logging.
Motors and Gearmotor from sub-fractional AC / DC to 5K HP AC (NO-LOAD, LOADED and production / Lab Dynamometers), Mechanical Gaging, PCB's, functional testers, Aerospace propulsion testing, R & D, ORT (On-line Reliability Test), EOL (End Of Line) and product life test.
Noise and vibration testing and source identification. New / existing products and machine PM.
Factory Controls, SCADA (Supervisory Control And Data Acquisition) and Instrumentation. PID and other controls work, Production tracking, error proofing and data logging.
You didn't mention any PLC control, so I take it that your systems is hard-wired. Without any detail of the travel limit switches available I would use these switches to switch a double pole relay to reverse the motor's direction. Another series-wired switch should kill the power to the whole system. This is the cheap solution.
An elegant solution would be to use a micro PLC like mentioned before. I also see these days that you get intelligent relays on the market, even a better solution from a cost point of view. Amongst others, try the Mitsubishi Alpha series or Moeller Easy relay and the cheapest I found is the FAB Giant relay.
When I've done this sort of thing (with DC motors) I set up my drive circuitry/software to only be able to stop or drive out of the limit switch, not drive in. This is fairly easy to do if your control circuit has a drive-in line and a drive-out line; you can do it with a few gates. Having no idea of what you're actually using to drive your stepper I can't say much more.
