Function:
Select the reference input to be used
for the second reference signal.
Parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source, and
parameter 3-17 Reference 3 Source define
up to 3 different reference signals. The
sum of these reference signals defines
the actual reference.
Function:
Select the reference input to be used
for the third reference signal.
Parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source, and
parameter 3-17 Reference 3 Source
define up to 3 different reference
signals. The sum of these reference
signals defines the actual reference.

3-18 Relative Scaling Reference Resource
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select a variable value to be added to the
fixed value (defined in
parameter 3-14 Preset Relative Reference).
The sum of the fixed and variable values
(labeled Y in Illustration 4.9) is multiplied
by the actual reference (labeled X in
Illustration 4.9). This product is then
added to the actual reference (X+X*Y/100)
to give the resulting actual reference.
