DIAMETER CALC.
This block calculates the diameter of a reel
as a function of the reel speed and the line
speed.

Parameter Descriptions
LINE SPEED Range: -105.00 to 105.00 %
This will usually be configured to be the analog tacho input and scaled appropriately during
calibration.
REEL SPEED Range: -105.00 to 105.00 %
This will usually be configured to be the drive's own speed feedback, i.e. encoder or arm.volts
feedback
MIN DIAMETER Range: 0.00 to 100.00 %
This is normally the empty core diameter.
MIN SPEED
Range: 0.00 to 100.00 %
This is the minimum LINE SPEED level below which the diameter calculation is frozen.
RESET VALUE Range: 0.00 to 100.00 %
Normally for winders this will be set to the MIN DIAMETER value. This value will be
preloaded into the ramp (filter) output when EXTERNAL RESET is enabled.
EXTERNAL RESET Range: ENABLED/DISABLED
Whilst this input is being enabled the ramp is held at the RESET VALUE.
RAMP RATE Range: 0.1 to 600.0 SECS
This is used to filter the output of the diameter calculator.
DIAMETER Range: 0.00 to 100.00 %
This is the output of the block and it can be connected to the appropriate points in the winder
block.
