Marco,The datasheet for the UPR Air Family lists many optional encoders in the appendix. Which of these encoders is the UPR-160 using?

We are using a micosIOC (https://github.com/epics-motor/motorMicos.git <https://github.com/epics-motor/motorMicos.git>) to control an UPR-160 motor: https://www.pi-usa.us/fileadmin/user_upload/pi_us/files/product_datasheets/Air_Bearing_Rotation_Stages_UPR-Air_Family.pdf <https://www.pi-usa.us/fileadmin/user_upload/pi_us/files/product_datasheets/Air_Bearing_Rotation_Stages_UPR-Air_Family.pdf>According to the motor technical data, its resolution can go down to 0.00004 degrees. The current IOC has a motor with .MRES=0.04 deg, so we cant make movements smaller than this. When i caput MRES to 0.004, i can caput .VAL from 0.1 to 0.105, for example, and the motor will move.
