Using Siemens PLC Function Blocks: MC_Power and MC_Reset 

🫡

There absolutely is! Depending on what telegram you are using you can either use a free bit in the control word (PZD1 of the RECEIVE telegram) or you can tie the DO9 to the status word. I will have a livestream tomorrow morning and I will show how to do this. If you can't catch it live, watch it on demand. I will go through it first thing.

Thank you sir! :)@@jasonwattsae

You are welcome!

I have a video for these blocks coming out but it will be a few weeks so here is the basics: You will use MC_Gearing or MC_GearingAbs. You will have to have the TO set up as a "Synchronous Axis" with whatever axis you are wanting to gear to selected in the "Master Axis" section of the Configuration. The easiest to configure is MC_Gearing as it does not have a synch point, so it uses the velocity and acceleration configured on the block and once it synchronizes with the master it is "in gear". The MC_GearingAbs does a calculation that uses the velocity and acceleration parameters to sync with the master Axis at a specific point (master sync position). There are a few more details on this one that could make it more difficult to work with. What is your application?

@@jasonwattsae Thank you I will waiting for watch the video.

@@jasonwattsae My application is winder and unwind machine.

@@vorapobautomation9760 The program these MC videos are shot on is a center-wind roofing roll winder.

@@jasonwattsae How did you calculate speed of unwind and rewind motor inorder to keep line speed ?
