Scale the maximum output of the selected analog
signal at terminal X45/1. Set the value to the
maximum value of the current signal output.
Scale the output to give a current lower than 20
mA at full scale, or 20 mA at an output below
100% of the maximum signal value. If 20 mA is
the required output current at a value between 0–
100% of the full-scale output, program the
percentage value in the parameter, for example
50% = 20 mA. If a current 4–20 mA is required at
maximum output (100%), calculate the percentage
value as follows (example where required
maximum output is 10 mA):

Parameters for configuring the scaling and limits for analog
output 4, terminals X45/3 and X45/4. Analog outputs are
current outputs: 0/4 to 20 mA. Resolution on analog
output is 11 bit.
