The Film Feeder Parameter Settings
41 Drum load position : 7394
This parameter controls the load position of the drum. This is the physical position
where the upstanding surface of the spoiler lies a short distance above the
film edge when the film has been presented to the drum using the film feeder
bridge. Distance “spoiler  filmedge” is drumdepending. Important is that
the other side of the film is just over the last vacuumslits. Between 1 and 2
millimeter.
42 Drum unload position : 811
This parameter controls the unload position of the drum. This is the physical position
where the beginning of the film lies about 1 cm before the unload table,
mounted on the roll down system.
43 Unload to inline distance : 4000
This parameter can be left to the value of 4000. This parameter ensures that during unload the
first detector in the in-line system should recognize the film before the drum has rotated the
parameter steps. In this case 4000 steps. If it doesn’t see the film the following message
appears:
Warning Recovering film transport to inline
Warning Recovering film transport to inline
Warning Recovering film transport to inline
Error : EZ Unable to unload: can not put film on inline
44 Drum stepper period : 750
This parameter can be left to the value of 750. This controls you the speed of
the stepper motor during unload and positioning drum during load. With this
period the fastest speed is obtained with minimal noise. The lower the value,
the higher the stepper motor speed.
45 Drum stepper acceleration : 6000
This parameter can be left to the value of 6000. This controls the acceleration of the
stepper motor during unload and positioning drum during load.
46 Load alignment distance : 0
This parameter controle the alignment distance during load. This parameter can be left
to the value of 0.
47 Film from drum release time (ms) : 5000
This parameter controls the extra wait time during the unload procedure before the film is pushed
up to the unload table.
48 Wait before take over (ms) : 1000
This parameter controls the extra wait time before the take over cylinder is pushed
forward. Normally the software detects when the film feeder bridge is
up. But this doesn’t mean that the film feeder bridge is physically at it’s
end position. This depends on the location of the reed switch on the
rotary cylinder. This extra delay can be compensated with this parameter.
This parameter can be left to the value of 1000.
