SPEED CALC
In this function block line speed is summed
with the over speed input (only if in open-
loop mode) and the closed loop trim (for
closed loop winders) from the PID output
SPEED TRIM. The combined speed demand
is divided by the diameter to produce the
SPEED DEMAND to the drive.
Refer to Macro 4.

Parameter Descriptions
REWIND
Range: FALSE / TRUE
The Rewind mode is selected when TRUE.
OVER-WIND
Range: FALSE / TRUE
The Overwind mode is selected when TRUE.
OVER SPD ENABLE
Range: FALSE / TRUE
When TRUE, Over Speed is enabled which saturates the speed loop.
UTS THRESHOLD
Range: 0.00 to 110.00 %
Threshold level which defines the state of UP TO SPD (UTS).
LINE SPEED
Range: 0.00 to 110.00 %
Actual line speed (from the DIAMETER CALC function block).
MOD REEL SPEED
Range: 0.00 to 110.00 %
The absolute value of the WINDER SPEED (from the DIAMETER CALC function block).
DIAMETER
Range: 0.00 to 110.00 %
The diameter input (from the DIAMETER CALC function block).
MINIMUM DIAMETER
Range: 0.00 to 120.00 %
The minimum diameter input (from the DIAMETER CALC function block).
OVER SPEED
Range: -100.00 to 120.00 %
A value of over speed which, when added to the calculated speed, will saturate the speed
loop.
