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

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.
