I suspect that the problem is probably in the device driver that EZwarePlus loads for your PLC. There have occasionally been similar problems with the Omron drivers.

I suspect you will also need to be concerned about the amount of heat that the motor will generate with all the starting and stopping. It will probably at least need a constant running cooling fan.

If you are using a rack and pinion that would mean the motor has to start and stop for each direction?? I doubt that a 7.5 hp gear motor is going to last long doing that.
