VLT AutomationDrive FC 301/302
Function:
Reference from terminals 68 and 69.
Function:
Select the reference input to be used
rd
for the 3 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.
Reference from terminals 68 and 69.
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 3.24) is
multiplied by the actual reference
(labeled X in Illustration 3.24). This
product is then added to the actual
reference (X+X*Y/100) to give the
resulting actual reference.
