OS ENCODER CONFIGURATION
The “ Absolute single turn Sin/Cos encoder ” configuration (Heidenhain ERN 1085 or compatible) is selected
according to the following COM and COD jumpers setting (
see chapter 5, section 1: Hardware adjustments
The corresponding X1 connector pin function description is given below.
