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.
