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 analogue 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 P2847 - HYD_Val. These values will
also be used for control purposes.

Image 7.58: “Hydraulic signal scaling, volumetric flow rate” screen
P2845 - 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 P2846 - 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 analogue 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 P2847 - HYD_Val. These values are
transferred to the controller.
7.11.3.2.3Signalscaling,pumpspeed
Image 7.59: “Hydraulic signal scaling, pump speed” screen
P2845 - HYD_Input_Val displays the unscaled pump speed reference value of the
pump speed control.
Further processing and scaling is carried out in P2846 - 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 analogue 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 P2847 - HYD_Val. These values will
also be used for control purposes.
