Outputs

Parameters

dnLineSpeed_n

DINT

Material speed setpoint in [%]

• 100 % ≡ maximum material speed (dwReferenceLineSpeed)

dwRefDiameter

DWORD

Reference diameter for pre-switch-off and switch-off signal in [μm]

• 1000 μm ≡ 1 mm; 1000000 μm ≡ 1 m

• Internal limitation to 10 m

Identifier/data type

Value/meaning

dwLengthToRef

DWORD

Residual length until reaching the reference value in [mm]

• Internal limitation to 2000 km

dwTimeToRef

DWORD

Residual runtime until reaching the reference value in [s]

• The calculation depends on C04880, either on the basis of the material speed set-

point or the maximum material speed.

• This value is only calculated at every 2. call of the FB (alternating with

dwStopLength).

dwStopLength

DWORD

Change in length during the braking phase in [mm]

• This value is only calculated at every 2. call of the FB (alternating with

dwTimeToRef).

bStartDec

BOOL

Control signal for starting the braking process

TRUE Pre-switch-off length reached.

bRefReached

BOOL

Control signal for triggering the limit stop

TRUE Reference length dwRefLength reached.
