Hello all

We have SINAMICS DCM in the (control unit) expert  list I couldn't find any help for some parameter, for example I want to know what is the parameter  (p21974).

there is no help or manual for parameter (21000 - 25999)

regards

In the project pane, click the + beside SIMATIC 300(1) to expand it.  Expand until all items are expanded.  Then post a screenshot.

I suspect there are DCC CFC charts in that control unit and p21974 is an interim bit in one of the charts.

By expanding everything, you may be able to see there are DCC / CFC charts in use on the drive.  Then with a CFC editor, you can find that parameter and what is causing it to be mapped to SCR1: r2091.0 (ProfiDRIVE PZD2 word bit 0).

Dear expert 

thank you soooo much for your reply. you are right I found that CFC.

is there any manual related to configuration of this type DCC cfc chart?

thank you.

I attached the cfc photo.

I may be misreading the CFC (I have only worked on DCC/CFC in S120 drives), but it looks like there are 9 SCR_1 CFC charts.

Look in CFC4.jpg.  In the menu bar is the #1 with a drop-down selector arrow.  Click that arrow to see if there are charts in the # 2 - 9 selections.

CFC is (to me) like a graphical STL that's kind of like FBD and STL, or possibly "Visual Assembly" language is another way to think of it.

On the left are inputs.  On the right are outputs.  In the middle are logic blocks that process inputs and resolve to outputs.

NOTE: some outputs can go to other CFC screens or charts.

SCR_1 is a "chart".  "SCR_1 CFC1" is the first chart in SCR_1.  I think chart 2 would be "SCR_1 CFC2/9" in the status bar - far right.
