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 4.17) is multiplied by the
actual reference (labeled X in
Illustration 4.17). This product is
then added to the actual reference
(X+X*Y/100) to give the resulting
actual reference.
