text: <s>[INST] PF755 with SSI absolute encoder. We have several cranes controlled by PF755 drives. Is usefull for operator to know hook position aproximately. The motor has incremental encoder, i implemented a datalink to read parameter 847 (Psn Fdbk). When the hook touches maximum up limit switch, the PLC saves this homing position. Substracting Homing position to parameter 847 and dividing by conversion constant is possible to know the hook position in engineering units. Well, now i have another crane. But in this, operators normally don't move hook to maximun up position. So is difficult to get a homing position and after every restart of drive is neccesary to recalibrate if i use an incremental encoder. To avoid the need of get a homing position frecuently, i was thinking in using an absolute encoder connected to an Universal Feedback card. I want to use an IFM RM8001 absolute encoder. I suppose i must connect the encoder as in this diagram. Is correct? UFB Encoder -Xc Green clock +Xc Yellow inverted clock -Xd Gray Data +Xd Pink Inverted data 12c White 0V +12 Brown Ub Do you think is possible to read absolute encoder position in PF parameter 847? I suppose that after drive restart, the UFB card will read the ansolute encoder position and will not start in cero. So if i get homing position in startup i will not need to get it again until reconfiguration or change/repair motor. is correct?
