5.3 Menu STATUS
The displays appearing in this menu are status displays only. It is
not possible to change or set values.
The displayed values are the values that applied when the last

status value is to be updated, point the R100 at the control panel
and press "OK". If a parameter, e.g. speed, should be called up
continuously, press "OK" constantly during the period in which the
parameter in question should be monitored.
The tolerance of the displayed value is stated under each display.
The tolerances are stated as a guide in % of the maximum values
of the parameters.
