Set parameter 76.01 Diameter calculation
mode to External feedback at
Define the source for the diameter feedback
signal.
Note: Scale the feedback source according
to minimum/maximum diameter in mm. For
more information, see parameter description
on page 425.
Set the rest of the parameters as in the case
of Estimated mode.
After all diameter calculation settings are
complete, it is recommend to set the
parameter 76.11 Reset estimated
Select the source for speed reference and scaling factor.
Set parameter 75.01 Max line
on this value. The application program
calculates the maximum motor speed (signal
75.61 Max motor speed at
Note: Make sure these settings do not
exceed the maximum/minimum motor speed
limits in group 30 Limits.
Select the source for line speed reference.
Set the line speed reference input scaling
range. The target speed reference is defined
as:
75.51 Line reference In
reference src/ 75.03 Line reference
* 75.01 Max line speed.
Note: Reference scaling could be set to 0,
then the input from parameter
interpreted directly as m/min (of ft/min)
without any scaling.
If line speed reference is fed through
fieldbus, then set the correct PLC program
execution cycle time or communication cycle
time whichever is longer.
The control program will use this information
to synchronize the incoming speed
reference with other functions, e.g., when
Inertia compensation function is active.
