text: <s>[INST] PowerFlex 755 Dual Encoder AqB Feedback. Summary: PowerFlex 755 CIP Motion With Dual Encoder AqB Feedback. Manuals are contradicting themselves.Hello all, Can you have a Universal Feedback Card in a PowerFlex 755 Drive and use Dual AqB Feedback on Both Channels with two A B Z encoders? I'm working on a project which involves dual encoder feedback and CIP motion (I've listed the hardware and software which I'm using at the bottom of the post). I've found that there is some contradictory information in the PowerFlex 750-Series AC Drives Programming Manual (750-pm001) and the PowerFlex 750-Series AC Drives Technical Data (750-td001). The PowerFlex 750-Series AC Drives Programming Manual Appendix F (Page 522) shows that in Table 30 Universal Feedback Type and Connections that Digital AqB can be used. The wiring for the terminals are shown in the table. The PowerFlex 750-Series AC Drives Technical Data Encoder Combinations Compatible with Universal Feedback Boards(Page 153) shows that two incremental A B Z encoders can't be used. I've attached Images of both tables to this post. (One is the image attached to the post, the other is the file. There seems no way for linking multiple images). Can anyone provide some more detail on AqB? Which encoders use this feedback type other than A B Z? Hardware: Guard Logix 5580 Controller (1756-L82ES). PowerFlex 755 AC Drive with Embedded Ethernet/IP & Safe Speed Card (20G11NB2P2JA0NNNNN). Software: Studio 5000 Logix Designer Version 31. RSLinx Classic Version 3.51.00 or Later. Cheers, Spencer P. [/INST] I am completely lost not being able to find what fault code 10138 is all about on the fault code manual for powerflex 755. Can someone guide me on this? \\n </s>
