COM2 Function
9.9.14 Data on the total control deviation
The total control deviation is comprised of the sum of the control deviations for performance quantities
and work quantities combined and refers to the speci
fi ed areas.
In direct reference to the acquired input and controlled variables, the maximum deviation to the target
value is <
± 5 %. By activating the menu-assisted adjustment, the total control deviation can be
reduced to a value of < ± 1 %.
For indirect reference of the acquired input value to the controlled variable, i.e., two physical variables
still need to be converted, the deviation can be reduced to <
± 5 % through adjustment.
In the case of an internal default value through the integrated or external terminal, the control deviation
remains at <
±
0.5%.
