49 Wait after take over (ms) : 3000
This parameter controls the extra wait until the next step in the load procedure is performed until
the take-over cylinder hits the take-over table. The speed (and time) that the take-over cylinder
hits the take-over table is controlled via the third speed controller. The slower the speed the
longer it takes to hit the take-over table the higher the value of this parameter should be.
This
parameter can be left to the value of 3000
50 Load drum stepper period : 1200
This parameter can be left to the value of 1200. This will give you the speed of the
stepper motor during the winding of the film around the drum during the load
procedure. The higher the value, the lower the stepper motor speed.
51 Load drum stepper acceleration : 600
This parameter can be left to the value of 600. This controls the acceleration of the
stepper motor during the beginning of the winding of the film around the
drum during the load procedure. This value can supply a slow acceleration of
the stepper motor. A lower value compared to the unload acceleration is
needed, otherwise the chance of loosing the film at the start of the winding is
higher.
52 Wait after suction caps off (ms) : 2000
This parameter controls an extra delay before the next step in the load procedure is
performed. It waits until the film hits the drum after the vacuum in the
suction caps is gone.
53 Wait after blower on (ms) : 2500
This parameter controls the extra wait time after the on signal of the vacuum pump
before the next step in the load procedure is performed. The reason for this
parameter is to ensure that the vacuum level is reached before winding the
film around the drum. If the correct vacuum level is not reached in time, the
chance of loosing the film during the winding of the film around the drum is
higher.
54 Timeout inline to online (ms) : 20000
This parameter can be left to the value of 20000. This parameter sets the time that
the film has to reach from the I.R. detector in the inline to the I.R. detector in
the conveyor in normal procedure. If the I.R. detector of the conveyor
doesn’t recognize the film in time then it will shut off the motors of the two
transport systems. This is needed if your working in backup mode (= second
transport system is put up so that the films drop in the unload drawer).
55 Timeout online to processor (ms) : 30000
This parameter sets a timer that starts running when the I.R. detection of the
conveyor recognizes the film. The time indicated in this parameter is the time
that the film has to clear from the I.R. detector. If this is not the case, the
motors of both transport systems are shut off. If the film stays over the I.R.
detector, the second transport system will goes into backup mode.
