Th articlenumber of my encoder is PEC11R. My goal is to rotate the motor to a direction that is determined by the encoder. So if I turn my encoder to the right the DC Motor turns right vice versa. The motor keeps rotating as long as I also keep rotating the encoder and if I stop rotating the encoder the motor stops too. I did the wiring, but I don't know what functions to use and how to program. Can someone help me?

With the Motion Control instruction "MC_GearInPos", you start a gearing operation between a leading axis and a following axis. The synchronous operation is synchronized in advance of the specified synchronous position for the leading and following axis. But this function is not available with S7-1200, a S7-1500 is needed. With the functions for a S7-1200 you may do this not synchronous, like turn the encoder and when you got the new position you need to turn the motor the same, with MC_MoveXxx function: S7-1200 Motion Control as of V6 hope this helps, regards,

Like this video: https://www.youtube.com/watch?v=K7FQSS_iAw0 Except the difference between this video and what I want to do is that in stead of using a phone, I will be using an encoder. Please can you give me an explanation on how to get this together with a PLC.
