I havesix MM440 drives communicating with S7-1200 1214C (6ES7 214-1BG31-0XB0) through CB 1241 (6ES7 241-1CH30-1XB0). Program is made using TIA portal V13 according to the great tutorial: https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=60978927&caller=view. Commands and speed setpoints are sent todrives. Everything works except.... USS_PORT signals error 8188(Illegal PZD word length specified) for all drives and there is no feedback from the drives. For example,I don't see the actual drive speed. Since everything else works, it is not a high priority butI still would like to understand what is the problem. Can anyone help please? |

It sounds like the telegram for data coming from the drive is not the same in the drive as it is in the plc for all 6 drives. Find that setting in each drive, compare to what you have in the plc, and fix whichever one is wrong. |
