keys on
the control panel.
On each screen, information is displayed in 5 segments:

(fig. 3.2 - screen 1). The individual screens
differ only in the information displayed in the segment
4
. Information displayed in this segment is used to monitor 3
selected values (separately for each screen) – eg. supply voltage Ulin, set frequency fRef, process speed nPro, etc. Any
parameter from the "0 Preview" group can be displayed. Additionally, for the first two lines of screen 1, two different
monitored values can be set - separately for Run and Stop status of the drive. A detailed description of changing the
displayed values is provided in section 3.4 “Changing the values displayed in the basic view”. Fig. 3.2 shows the default
displayed values.
