www.controltechniques.com Issue Number: 10
The variable selectors allow two source values (defined by Pr 12.08, Pr 12.28 and Pr 12.09, Pr 12.29) to be combined as defined by the mode
(Pr 12.10, Pr 12.30) to produce an output (Pr 12.12, Pr 12.32) which can be routed to the destination parameter (defined by Pr 12.11, Pr 12.31). The
actions of the variable selector are defined by the mode parameter as given below. If the mode parameter is changed or the variable selector is
disabled because neither source is routed to a valid parameter all the internal state variables (i.e. time constant accumulator, etc). within the selector
are reset. When the Sectional control mode is selected the function is also reset, and the output is held at zero, when the control (Pr 12.15 or
Pr 12.35) is zero. It is active when the control has a non-zero value.
