I started off yesterday not knowing a thing about stepper motors, so hopefully this makes some sense and i am not missing something simple and/or obvious.
I need to control 8 stepper motors. Travel is not over too great of a distance, but accuracy is fairly critical. There is no "program" that will control these, rather we will have some sort of input device (1 for each motor) that will tell the motor to move X distance. The first way that i thought to do this was with a Siemens S7-226 with the EM 253 position module. But it looks like i will need 1 module for every motor, is that correct? If so, one CPU cannot handle that many modules.
It seems to me that there has to be an easier way to accomplish this. In a previous post someone mentioned that an easier way would be to use a ET200S CPU and a pulse output module. Is that all the EM253 does, send a pulse output to the Stepper Drive?
I apoligize for not having some of the basic concepts down, i am confident i can figure out whatever is necessary, i just dont know the appropriate place to start. If there is a simplier approach i am all ears. I can give more details, but this is getting sort of long and i am not sure which information is relevant.
