Change BISS settings
If the analogue signals do not cause an error or there are no analogue signals, but you get feedback errors related to the digital signals (e.g. F717, F718, F72x,...) please doublecheck the wiring and the number of position bits.
If you are not sure about that number you may try changing values for "Bit resolution singleturn position" and "Number of clockcycles to get singleturn position".
