plc stepper controler


Thread Starter


hi to all.

I'm trying to control stepper motor trough plc, siemens s7 s200. i have l298 as motor driver and plc would replace ic like l297, analog outputs would be trimed input level of l298. does anyone have an idea how to program plc in ladder so i have inputs of cw/ccw, full step/ half step, # of inpulses and time and outputs that can go to l298 inputs, a, b, c, d and enable? Oh and i have little experience, i need this for my school project, any help is appreciated. Tnx in advance
