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 ≡ 1m
• 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.
Parameter Possible settings Info
C04880 Reference value = Stop length of reference value
• Reference value for the rated de-
celeration time dwNominalTif
• Initialisation: maximum material
speed
0 Maximum material speed
(dwReferenceLineSpeed)
1 Material speed setpoint
