If analog input 1 is programmed in any of the modes 2 to 5 (see Pr 7.06 on page 82) then this bit is set if the current input falls below 3mA. This bit can
be designated to a digital output to indicate that the current input is less than 3mA.
An offset can be added to each analog input with a range from -100% to 100%. If the sum of the input and the offset exceeds ±100% the results is
limited to ±100%.
This offers a simple control of Pr 7.19 to change the analog output. Its function is used to set the value of Pr 7.19 between a frequency output, load
output, current output, or power output, or to leave the value unchanged. A user wishing to change the analog output to something other than these
must first program this parameter to USEr (or 4).
