Function:
Select the reference input to be used for the third reference signal. Par. 3-15, 3-16 and 3-17 define up to three
different reference signals. The sum of these reference signals defines the actual reference.
Function:
Select a variable value to be added to the fixed value (defined in par. 3-14
of the fixed and variable values (labelled Y in the illustration below) is multiplied with the actual reference
(labelled X in the illustration below). This product is then added to the actual reference (X+X*Y/100) to give the
resultant actual reference.
This parameter cannot be adjusted while the motor is running.
