Function:
NOTE
This parameter cannot be adjusted
while the motor is running.
Select a variable value to be added to the
fixed value (defined in
). The sum of the fixed and
variable values (labelled Y in
) is multiplied with the actual
reference (labelled X in
).
This product is then added to the actual
reference (X+X*Y/100) to give the resultant
actual reference.
