26-52 Terminal X42/9 Max. Scale
Range: Function:
100.00 %* [0.00 - 200.00 %] Scale the maximum output of the selected analog signal at terminal X42/9. Set the value to the
maximum value of the voltage signal output. Scale the output to give a voltage lower than 10V at
full scale; or 10V at an output below 100% of the maximum signal value. If 10V is the desired output
current at a value between 0-100% of the full-scale output, programme the percentage value in the
parameter, i.e. 50% = 10V. If a voltage between 0 and 10V is desired at maximum output, calculate
the percentage as follows:
(
10 V
desired
maximum voltage
)
x 100 %
i.e.
5 V :
10 V
5 V
x
100 % = 200 %
See principle graph for par. 6-52 Terminal 42 Output Max Scale .
26-53 Terminal X42/9 Bus Control
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the level of terminal X42/9 if controlled by bus.
26-54 Terminal X42/9 Timeout Preset
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the preset level of terminal X42/9.
In case of a bus timeout and a timeout function is selected in par. 26-60
Terminal X42/11 Output
the output will preset to this level.
3.24.8 26-6* Analog Out X42/11
Parameters for configuring the scaling and output function for analog output, terminal X42/11.
