3-16 Reference Resource 2
Option: Function:
Select the reference input to be
used for the 2
nd
reference signal.
Parameter 3-15 Reference Resource 1 ,
parameter 3-16 Reference Resource 2 ,
and parameter 3-17 Reference
Resource 3 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 4.17 ) 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.
