Description

lrSetDiameter

Data type – LREAL

Diameter in mm

Is set with xSetDiameter (e.g. start diameter).

xSetDiameter

Data type – BOOL

  • TRUE – lrSetDiameter active, lrSetDiameter is output without delay as lrDiameter.
  • FALSE – Diameter determination active, lrDiameter changes via the diameter filter.

xHoldDiameter

Data type – BOOL

  • TRUE – Currently determined diameter is frozen.
  • FALSE – Diameter determination active, lrDiameter changes via the diameter filter.

xUnwinder

Data type – BOOL

  • TRUE – Activate operation as unwinder
    INFORMATION: The direction of rotation must be specified opposite to the process direction.
  • FALSE – Activate operation as rewinder

lrActualLineSpeed

Data type – LREAL

Current path speed in m/min
(e.g. from a measuring wheel)

Only for "Calculate" mode (ST_Config_DiameterAcquisition)

lrDiameterSignal

Data type – LREAL

Output signal of a distance sensor
(unit analog signal)

Only for "DistanceSensor" mode (ST_Config_DiameterAcquisition)

stConfig

Data type – ST_Config_DiameterAcquisition

Configuration of the diameter acquisition

lrDmPersistent

Data type – LREAL

Assign lrDmPersistent to a variable in non-volatile memory for failsafe storage of the diameter.

Output signals drive

lrActualVelocity

 

Data type – LREAL

Current speed in min-1

For "Calculate" mode (ST_Config_DiameterAcquisition)

lrActualModuloPosition

Data type – LREAL

Current modulo position (unit – 0..1)

In "LayerCounter" mode or lrPlauCheckTol > 0
(ST_Config_DiameterAcquisition)

xStandstill

Data type – BOOL

  • TRUE – Drive at standstill
  • FALSE – Drive is rotating

For "DistanceSensor" mode or lrPlauCheckTol > "0"
(ST_Config_DiameterAcquisition)
