The average measured DC input voltage seen across the field controller A1 and A2

terminals.

This parameter displays the level of the analog signal present at the flux reference input,

this is a unipolar voltage input where the input range is 0 V to +10 V.

An offset can be added to flux reference input with a range from -100.0 % to 100.0 %. If

the sum of the input and the offset is outside the range 0 to 100 % the result will be

clamped at 0 or 100 %.

The flux reference input is connected to the field economy parameter when the flux

input is selected. The maximum value of the field economy is 100 % and so the default

for the scaling parameter is 1 so that the demand is 100 % for 10 V input.

The maximum value of Pr 02 is 860 which without any scaling will be converted to 10 V.

This parameter should be adjusted by the user for other full scale voltages.
