26-41 Terminal X42/7 Min. Scale
Range: Function:
0 %
*
[0 -
200 %] Scale the minimum output of the selected analog
signal at terminal X42/7, as a percentage of the
maximum signal level, example, if 0 V (or 0 Hz) is
desired at 25% of the maximum output value,
programme 25%. Scaling values up to 100% can
never be higher than the corresponding setting in
parameter 26-42 Terminal X42/7 Max. Scale .

Range: Function:

%
*
[0 -
200 %] Scale the maximum output of the selected
analog signal at terminal X42/7. Set the value to
the maximum value of the voltage signal output.
Scale the output to give a voltage lower than 10
V at full scale; or 10 V at an output below 100%
of the maximum signal value. If 10 V is the
desired output current at a value between
0-100% of the full-scale output, programme the
percentage value in the parameter, that is
50%=10 V. If a voltage between 0 and 10 V is
desired at maximum output, calculate the
percentage as follows:
10V
desired maximum voltage x 100 %
that is
5V : 10V
5V × 100 % = 200 %
26-43 Terminal X42/7 Bus Control
Range: Function:
0 %

[0 - 100 %] Holds the level of terminal X42/7 if
controlled by bus.
