I lost a direct logic 405 cpu on a piece of equipment and had no backup but had another piece of equipment that was basically identical. I placed a new plc into the machine and uploaded the program from the other machine to see if it was possible the two programs were identical. They only have one difference to them. The stepper motors that shuttle a guide back and forth is the only difference I see so far. When I installed the new program, the shuttle did not go to the end location is was suppose to go to. I have a dv operator interface with stop, speed and jog on there. The stop was initially set at 5300 and now when I turn it to 9999 it still does not quite shuttle to the required location. I need to know how to change the stepper count in the program. Please help.
