Using a PowerBrickLV 5/15A

Hi, we realized that we do not reach the same accuracy when tuning a motor and scaling motor units to user units. It becomes worse as the the scaling increases. In the worst case we have ~26222 motor units per user unit. We assume that there are rounding errors causing the problem. Therefore we wondered if there is a function which allows us to work in raw motor units and get the position output in user units. Ideally we would also like to be able to input the acceleration and speed parameters in user units.

If it is not possible my workaround would be to have a plc running in the background which does the conversion, or is there maybe a best practice?

Best regards,
