RATIO 1 Range: -3.0000 to 3.0000
Analog input 1 scaling.
RATIO 0 Range: -3.0000 to 3.0000
Input 0 scaling.
SIGN 1 Range: POSITIVE/NEGATIVE
Analog input 1 polarity.
SIGN 0 Range: POSITIVE/NEGATIVE
Input 0 polarity.
DIVIDER 1 Range: -3.0000 to 3.0000
Analog input 1 scaling. Dividing by 0 (zero) results in a zero output.

Input 0 scaling. Dividing by 0 (zero) results in a zero output.
DEADBAND WIDTH Range: 0.0 to 100.0 %
Analog input 1 deadband width.
LIMIT Range: 0.00 to 200.00 %
The Setpoint Sum
programmable limit is
symmetrical and has the
range 0.00% to 200.00%.
The limit is applied both
to the intermediate results
of the RATIO calculation
and the total output.
