26-51 Terminal X42/9 Min. Scale
Range: Function:
0.00 %* [0.00 - 200.00 %] Scale the minimum output of the selected analog signal at terminal X42/9, as a percentage of the
maximum signal level, for example if a 0 V is desired at 25% of the maximum output value. Then
program 25%. Scaling values up to 100% can never be higher than the corresponding setting in
par.26-52
