Description
Selects a mathematical function between the reference
sources selected by parameters
and 29.12 DC voltage ref2
voltage ref1 source.
Signal selected by 29.11 DC voltage ref1 source
DC voltage reference 1 as such (no function applied).
The sum of the reference sources is used as DC voltage
reference 1.
The subtraction ([29.11 DC voltage ref1
voltage ref2 source]) of the reference sources is used as DC
voltage reference 1.
The multiplication of the reference sources is used as DC
voltage reference 1.
The smaller of the reference sources is used as DC voltage
reference 1.
The greater of the reference sources is used as DC voltage
reference 1.
Configures the selection between DC voltage references 1
and 2. See diagram at 29.11 DC voltage ref1
0 = DC voltage reference 1
1 = DC voltage reference 2

1.
DC voltage reference 1 is used when external control location
EXT1 is active. DC voltage reference 2 is used when external
control location EXT2 is active.
