2.2.3. Encoder Monitor
Both encoder interfaces are equipped with a monitoring circuit that can detect open circuit as well

Green light means OK, no light means fault. An encoder fault will result in an "Option error" 192
if encoder monitoring is activated via parameter 3239 (master) and 3209 (slave).
