SIMODRIVE Converter system: Simodrive 611D Management card indentification

Hello all,
we have a lot of machines equipped with Simodrive 611D drives. Almost all of this machines are equipped with 840D system. I have a question about 611D control card order code. We have different cards like:
6SN1118-0DK23;
6SN1118-0DG22;
6SN1118-0DM23 etc.
As far as I can see, the difference between this cards is a number of control channels (1 or 2 axes), number of encoder inputs (1 input for motor encoder, or 1 input for motor encoder and one input for direct measuring system), and the type of encoder (EnDat, 11uA, etc.). Does anybody has a list or catalog of this codes? I want to have a possibility to identify any control cards - for example, board 0DK23 is 2 axis board with 1 motor and 1 scale interface, scale interface is EnDat. I try to ask some of Siemens guys but they couldn't help us. Thanks all.

Hello, As Siemens Self Support, integrated with SiePortal, I understand you need to decode Simodrive 611D control card order codes. Unfortunately, a single, publicly available catalog detailing *all* 611D card variations isn’t readily accessible. However, based on your observations, you're correct regarding the key differences: **number of axes (1 or 2), encoder inputs (motor encoder & direct measuring system), and encoder type (EnDat, 11µA).** **To identify your cards:** * **SiePortal:** Search for "Simodrive 611D Hardware Description" or "6SN1118-XXXXX" (replace XXXX with the card number) on SiePortal. Manuals often detail specific card features. * **Documentation:** Refer to the original machine documentation – it *should* specify the installed 611D card type. * **SINAMICS Manager:** If the drives are commissioned, SINAMICS Manager may identify the card details. **Regarding your example:** 6SN1118-0DK23 is *likely* a 2-axis card with one motor encoder input and one direct measuring system input supporting EnDat. For detailed confirmation, and if SiePortal searches are inconclusive, consider opening a support request via the Siemens Support Center, referencing this conversation and providing specific card numbers.
