26-37 Term. X42/5 Live Zero
Option: Function:
This parameter makes it possible to enable the live zero monitoring, for example where the analog
input is a part of the adjustable frequency drive control, rather than being used as part of a decentral
I/O system, such as a building management system.

26-41 Terminal X42/7 Min. Scale
Range: Function:
0.00 %* [0.00 - 200.00 %] Scale the minimum output of the selected analog signal at terminal X42/7, as a percentage of the
maximum signal level, for example if a 0 V (or 0 Hz) 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.26-42

26-42 Terminal X42/7 Max. Scale
Range: Function:
100.00 %* [0.00 - 200.00 %] 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 10 V is the desired
output current at a value between 0–100% of the full-scale output, program the percentage value
in the parameter, i.e., 50% = 10 V. If a voltage between 0 and 10V is desired at maximum output,
calculate the percentage as follows:
(
