Shift between external and preset via a
command or a digital input.
Function:
Enter a percentage (relative) value to be either
added to or deducted from the actual reference
for Catch up or Slow down respectively. If Catch
up is selected via one of the digital inputs
(E-01 Terminal 18 Digital Input to E-06 Terminal 33
Digital Input), the percentage (relative) value is
added to the total reference. If Slow down is
selected via one of the digital inputs
(E-01 Terminal 18 Digital Input to E-06 Terminal 33
Digital Input), the percentage (relative) value is
deducted from the total reference. Obtain

Option: 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 F-64 Preset Relative
Reference). The sum of the fixed and
variable values (labelled Y in
Illustration 3.14) is multiplied with the actual
reference (labelled X in Illustration 3.14).
This product is then added to the actual
reference (X+X*Y/100) to give the resultant
actual reference.
