Dear All Experts of SIEMENS MOTION CONTROL,

Motion control with me is NOT familiar. i read more manual of motion control but i am really not good with Synchronous Axis. I HOPE  the Expert forum can help me more.

i am doing the project with scope control: the plant have existing Roller. Now they need to add one more New Roller. So that, i need NEW ROLLER must synchronous (speed&position) with existing roller VIA EXTERNAL EnCODER.

Hardware of Project:

1. PLC CPU 1511T-1 PN

2. SINAMICS S210 FOR A ROLLER SERVO (new roller)

3. PROFINET ENCODER MODULE (for read EXTERNAL ENCODER)

My target: use technology "external encoder" as master to make the new Roller Axis synchronous about Position and Velocity. (ex: external encoder at position 250mm, then Roller Axis also at 250mm. it mean "new Roller axis" must same position with "position External Encoder" all time).

i am developing follow:

- Use "MC_GEARINPOS". Master "ExternalEncoder Axis" and Slave " Synchronous new Roller Axis".

- Execute: always on

i am really not sure about what it is possible work?

1. the Concept Design technology work? it is mean, can i use "External Encoder technology" to make "new Roller Axis" synchronous (position&speed)  all time. Existing Roller  New Roller same Position and Speed all time.

2. If Concept possible WORK, CAN I SIMULATION HOW IT WORK BY PLCSIM? HOW CAN SIMULATION ENCODER?

i also attached picture for configure of Projects. Please can take a look

I MUCH APPRECIATED YOUR SUPPORT!

 Dear jacek,

The first, thank you very much!

what can i do the SIMULATION Encoder to know it is really work? now i develop code with Synchronous but don't know SYNCHRONOUS work? if you know please teach me how to test them without Hardware?

Many thanks!

I'm afraid I have not enough knowledge of and experience with the PLCSim to help you.

But I can give you a hint, not really knowing if it's possible with the PLCSim though. Create a virtual axis and use it in place of the external encoder for simulation.

 Dear Jacek,

your way i did as well before. it worked with Virtual Axis. But i really need to make sure Technology External Encoder can Syn well by SIMULAITON TEST

Thank you very much!

If your axis syncs to a virtual master then there are fair chances it will sync to an external encoder.

The "only" problem you will get is signal quality (amount of noise) from a real encoder and possibly need for extrapolation. But this can't be checked with the PLCSim I think.

 Dear Jacek,

Good advice!

Thank for your support!
