NOTE
Users wanting to output load should be aware of the maximum values of the parameters they are routing to the output.
The maximum value of Pr 4.02 (active current) is the maximum level of current that the drive can operate at which is drive rating x 2. Therefore, at
rated load the analog output will be 1/2 x 10 = 5V.
Users wishing to see 10V output at 100% load will need to set Pr 7.19 to Pr 4.20 and Pr 4.24 = 100.

Range
0.000 to 4.000
Default
1.000
Update rate
21 ms
This parameter can be used to scale the analog output if so desired. However in most cases it is not necessary as the output is automatically scaled
such that when the source parameter is at its maximum, the analog output will be at its maximum.

Range
OFF(0) or On(1)
Update rate

If analog input 1 is programmed in any of the modes 2 to 5 (see Pr 7.06 on page 104) then this bit is set to On(1) 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.

Range
±100.0%
Default
0.0
Update rate
5 ms
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).
