Function:
Scale the minimum output of the selected analog signal at terminal X42/7, as a percentage of the
maximum signal level. E.g. if a 0 V (or 0 Hz) is desired at 25% of the maximum output value. Then
programme 25%. Scaling values up to 100% can never be higher than the corresponding setting
Terminal X42/7 Max. Scale
in par. 26-42
Terminal 42 Output Min Scale
See principle graph for par. 6-51
Function:
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 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:
