so long story short i built my own trainer at work so i could toy around with various things and test things and learn. well today i started with learning motion logic in studio5000. I have a M02AE card and a sew eurodrive TTL encoder(incremental). well i tried putting a BEI sensor card that lights up with A B and Z positions so that i could accurately tell when im getting phases and so on. my issue is i power the encoder and BEI card with 24v DC. off the encoder usually whatever phase is active im showing around 3-4v and the innactive phase will be around 1 so if A+ is 3.5 hen A- is 1 and so on. if i spin the encoder i can see the voltages change with position. my issue is on the BEI card i wired the controller side part to go back to the PLC. well none of the voltages fluctuate and none of the BEI cards lights go off. i noticed all the negative phases on the plc side of the bei card stay at 4 volts and the positives 0 and it does not change even when the topside of the card(encoder outputs) are fluctuating.
Now if i hook the wires from encoder straight to the m02ae card i can see in the plc that it is showing position and i can rotate it and itll change. My problem is im not sastified with that. i really want to know why the bei card in the middle is causing the plc to not see position so i can understand more.
Any help will be gladly appreciated!!!
encoder- OG72-DN-1024-R (i believe im not looking at it right now) ES1R model
1756-M02AE A rev 30
BEI Sensor module 600001-012 (same as encoder not 100 percent but its the 25 in/5 out module
