There are two scaling paths available for the actual pressure, actual pressure 1
(pact1) and actual pressure 2 (pact2). This allows two sensor signals to be
processed. A selection between an analog input or the hydraulic motion profile as
the signal source can be made for the reference pressure (pref).
The result after the scaling will be shown in P 2847 - HYD_Val. These values will
also be used for control purposes.
7.11.3.2.2 Signal scaling, volumetric flow rate
Image 7.58: “Hydraulic signal scaling, volumetric flow rate” screen
P 2845 - HYD_Input_Val will show the unscaled volumetric flow rate reference and
actual values for the volumetric flow rate control.
Further processing and scaling is carried out in P 2846 - HYD_Input_Adapt. A
scaling factor, an offset, and a signal limit (QAct_Min and QAct_Max) can be set.

A scaling path is available for the actual volumetric flow rate (QAct). A selection
between an analog input or the hydraulic motion profile as the signal source can be
made for the reference volumetric flow rate (Qref).
The result after the scaling will be shown in P 2847 - HYD_Val. These values are
transferred to the controller.
7.11.3.2.3 Signal scaling, pump speed
Image 7.59: “Hydraulic signal scaling, pump speed” screen
P 2845 - HYD_Input_Val displays the unscaled pump speed reference value of the
pump speed control.
Further processing and scaling is carried out in P 2846 - HYD_Input_Adapt. A
scaling factor, an offset, and a signal limit (nRef_Min and nRef_Max) can be set.
The actual speed is evaluated via the respective encoder input (see Section
"Encoder selection" on page 53). A selection between an analog input or the
hydraulic motion profile as the signal source can be made for the reference speed
(nref).
The result after the scaling will be shown in P 2847 - HYD_Val. These values will
also be used for control purposes.
