TAPER CALC
This function block profiles tension demand
with reel diameter for centre wind
applications.
This special block processes the tension and
taper set points to produce a composite
tension demand value as the diameter builds.
The TENSION DEMAND value is used to
set the motor current. This must be
connected to the DIAMETER and
MINIMUM DIAMETER parameters in the
SPEED CALC function block.
Refer to Macro 4.

Parameter Descriptions
HYPERBOLIC TAPER
Range: FALSE / TRUE
If set TRUE, a Hyperbolic Taper profile is applied which reduces the diameter more quickly
near the core and less as the diameter approaches the full roll.
If set FALSE, a Linear Taper profile is applied which linearly reduces the tension as the
diameter increases.
STALL ENABLE
Range: FALSE / TRUE
When TRUE, the tension demand is either:
STALL TENSION if FIXED STALL TEN is TRUE
or
STALL TENSION x TENSION SPT if FIXED STALL TEN is FALSE
When FALSE, Stall Tension is disabled.
BOOST ENABLE
Range: FALSE / TRUE
When TRUE, the tension demand is either:
BOOST if FIXED BOOST is TRUE
or
BOOST x TENSION SPT if FIXED BOOST is FALSE
When FALSE, Boost is disabled.
FIXED BOOST
Range: FALSE / TRUE
When TRUE and BOOST ENABLE is TRUE, then the tension demand is the value of
BOOST.
FIXED STALL TEN
Range: FALSE / TRUE
When TRUE and STALL ENABLE is TRUE, then the tension demand is the value of STALL
TENSION.
CURRENT CORE
Range: 0.00 to 120.00 %
The current core size (from the DIAMETER CALC function block).
DIAMETER
Range: 0.00 to 120.00 %
The calculated diameter (from the DIAMETER CALC function block).
BOOST
Range: -200.00 to 200.00 %
Sets a fixed boost, enabled by FIXED BOOST.
