9.8.6 123 Master encoder Stop compensation
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master encoder
“. With PWL2 only.
Setting the dead time of the stop sensor (label sensor) in order to compensate for the resulting delay.
9.8.7 124 Master encoder Mini loop on/off
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master encoder
“. With PWL2 only.
Switching the mini loop on or off. This mini loop is built after a delay (to be set via parameter 125) by
accelerating the web for a short time (distance to be set via parameter 126). The mini loop reduces the
tension load of the web.
9.8.8 125 Master encoder Mini loop start delay
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master encoder
“ and parameter 124 is set to „On“. With PWL2 only.
The delay in mm web transport after which the mini loop is built.
9.8.9 126 Master encoder Mini loop size
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master encoder
“ and parameter 124 is set to „On“. With PWL2 only.
The distance in mm on which the mini loop is built.
9.8.10 127 Master encoder rollfed Cutter distance
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master enc. Rollfed
“. With PWL2 only.
Cutter distance from cutting to cutting (with Rollfed only). Here you have to enter the distance from
cutting to cutting. With the help of this basic value the control program will calculate the required
speed profile for an exact feed of the foil.
9.8.11 128 Master encoder rollfed Difference StSt cont.
This parameter will appear only if parameter 110 (available only for Technical Service) is set to „02
Master enc. Rollfed
“. With PWL1 only.
With the help of this value the difference in position between start-stop mode and continuous pass-
through mode can be set. Due to the vacuum drum and the prolonged time for drawing in case of start-
stop operation usually the foil will be expanded more than with continuous operation. Here this
difference will be entered so that the edge of cut will always be at the same position.
9.8.12 140 Start signal
Rising edge (stand.):
Web transport is started with detecting the rising edge of the label.
Sensor mark:
Web transport is started on detection of a sensor mark. Use parameters 141 through 143 for
specifying.
