Interpretation of the measuring results
4.7.3
The measured signal accuracy will be displayed at the bar graph „System accu-
racy“.
Results higher than 0,7 indicates a high signal accuracy.
Results inbetween 0,7 and 0,4 indicates that signal accuracy is good but can be
increased by improving the mechanical mounting conditions.
Results less than 0,4 indicates a low signal accuracy maybe caused by moun-
ting conditions that are out of tolerance.
The interpretation of the measuring results can differ from that stated above and
depends on the type of axis, kind of drive etc.
