This is your encoder:  https://www.kuebler.com/en/products/measurement/encoders/product-finder/product-details/5873

Well, this is absolute encoder with ISS/BSSI interfaces and yes, it's RS-422/485 (differential line driver), but fx5U builtin rs-485 port is for serial communication and do not have standartd encoder profile protocols. Someone correct me if i'm wrong...

Here's how this encoder work's:  https://www.roboteq.com/index.php/applications/applications-blog/entry/how-ssi-encoders-works

This encoder have also SIN/COSINE A/B 1024 ppr incremental outputs, but it's also differential driver outputs (5V).

You can not red it with Fx5 since  the inputs need 24V +-10% signals.

Yes that is the encoder , and yes it wont work if connected to the inputs , had it connected with the 1.5k resistors and it doesnt make a difference if S/S is connected to 0v or 24v .

also i have checked the Rs-422/485 settings and i do not see any settings for this . 

Thank you for your reply , taught i was overlooking something on the settings.
