Ho Ca I have Siemens Simatic S7-1200, Stepper Motor Nema 23.-> i want to control 3 motors run at the same time. But 1212C has 2 PTO output. can u guide me use 1212c to control 3 steppers? Sir hello, I have to control 5 stepper motor in my project. I have control 4 motors by Pulse-1-2-3-4. I inserted Signal bord 4xdq 200kHz to my Plc. How should I add 5. PTO for controlling of my 5.stepper motor? I need your help,thank you. ------------------------------------------------------------------------------------------ Split from Control 3 stepper motor with S71200 1212 dc/dc/dc.

The S7-1200 PLC has a hard limit of 4 PTOs. This is evident in the hardware configuration. In the hardware configuration the PTO can be enabled and configured to map on-board outputs. The signal board extends the on-board outputs, but does not extend the count if PTOs. Are there any two stepper motors that are not used at the same time? If YES then the possibility is there to multiplex a PTO output through a relay.
