HI Guys
I am working an an indexing conveyor. to collect parts from a chute coming off a machine. After 250 parts i need to index to the next box.It will step 4 inch 2 times then reverse. Machine running at 50 strokes per minute. I need a stepper motor to do this. A counter with outputs will control when to step. Can i control ad steppers without a plc. I do not have to change programing parameters often, It takes 5lb/inch to move conveyer fully loaded. how big of a motor will i need. Any help will be appreciated, See attached photos.
