DIAMETER CALC
This block calculates reel diameter by
dividing line speed by winder speed for
centre wind applications.
The line and winder speeds are forced to be
of positive sign, independent of the input
speed sign. This ensures that the calculated
diameter is always positive.
The line speed input should be the actual
web speed from the previous section motor
speed (the next section in the case of an
unwind).
The winder speed is the spindle motor
speed.
Refer to Macro 4.

Parameter Descriptions
DIAMETER HOLD
Range: FALSE / TRUE
Freezes the output of the filter when TRUE.
PRESET ENABLE
Range: FALSE / TRUE
Presets the filter to core or external diameter. Enabled when TRUE.
SELECT CORE 2
Range: FALSE / TRUE
Selects between CORE 1 and CORE2 for use when PRESET ENABLE is TRUE.
CORE 1 is selected when FALSE. CORE 2 is selected when TRUE.
SEL EXT DIAMETER
Range: FALSE / TRUE
Selects external diameter input for PRESET ENABLE when TRUE.
TENSION ENABLE
Range: FALSE / TRUE
Enables Tension Control.
CORE 1
Range: 0.00 to 120.00 %
Core size as a percentage of the maximum diameter.
CORE 2
Range: 0.00 to 120.00 %
Alternative core size (as a percentage of the maximum diameter).
