Select the function of terminal 42 as an analog current output.
Function:
Scale the minimum output of the selected analog signal at ter-
minal 42, as a percentage of the maximum signal value. For
example, if 0 mA (or 0 Hz) is desired at 25% of the maximum
output value, program it to 25%. Scaling values up to 100% can
never be higher than the corresponding setting in par. 6-52.
Function:
Scale the maximum output of the selected analog signal at ter-
minal 42. 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 desired output current
at a value between 0 - 100% of the full-scale output, program
the percentage value in the parameter, i.e., 50% = 20 mA. If a
current between 4 and 20 mA is desired at maximum output
(100%), calculate the percentage value as follows:
