b) Set Fullscale Min/Max values for each calculated input signal.
c) Set Fullscale Min/Max values for each calculated output signal.
4. In Station Manager, define the required calculation for each valve’s calculated output signal.
a) In the Station Manager window’s toolbar, select the Configuration access level.
b) On the Station Manager window Tools menu, select Calculations Editor.
c) Select Calculated Analog Outputs, then select the first valve.
5. Define equations for the calculated output signal for each servovalve.
a) Select Calculated Analog Inputs on the Calculation Editor window navigation pane.
b) The expanded list displays all outputs for which calculations must be provided and represents the
outputs that may be used as commands for servovalves or other user-defined purposes.
c) Select the calculated output signal from the list for the first servovalve (for example, Valve 1).
d) Enter required equation in expression window.
Type text, select Insert function buttons, or click on selections from the Functions or Signals list.
Use the Apply button to enter each definition. Errors are displayed in the results panel. If there are no
errors, the results panel displays the word Success.
e) Repeat calculation editing to define the calculated output for the second servovalve.
About Matrix Two Channels Calculations
Problem
You need to create matrix control for translation and compression of two actuator channels during a test.
Solution
• Create a translation channel and a compression channel. The translation channel requires one control
mode (displacement), which is a calculated input. The compression channel requires two control modes
(displacement and load), which are both calculated inputs.
• Create calculated outputs to drive each actuator servovalve. Also, create auxiliary inputs (left/right load
and left/right stroke).
• Define the calculated inputs for translation displacement, compression displacement, and compression
load. Define calculated outputs to drive servovalves.
