AP 4.4 – AP 5.4 – AP 7.t
87
Start cur. len.
AP5.4
¯ Only in production mode.
¯ Only if SYSTEM PARAMETER > Periph. device = „Dispenser“.
Start current length
Duration of the start-up current superelevation. To be set is the feed length,
during which the increased current is supposed to flow.
XX mm Setting range: 10-40 mm; Default setting: 30 mm
Pullback current
AP5.4
¯ Only in production mode.
¯ Only if SYSTEM PARAMETER > Periph. device = „Dispenser“.
After a label was dispensed, the label web has to be pulled back under the
printhead. To reach this, the rewinder is rotated slightly in the opposite direc-
tion. The braking torque of the rewinder against this rotation may not be too
strong, otherwise this could decrease the impression accuracy. Because of
the brake torque depending on the diameter of the wound up label web, it has
to be corrected at the beginning (min. diameter) and at the end (max. dia-
meter) of the winding-up process. This is done by the Pullback current (sup-
ports the backwards rotation in case of low diameter) and the Brake current
(amplifies the brake torque in case of high diameter). Additionally can be set:
The diameter up to which the Pullback current is throttled down to zero
(parameter Back diameter), and the diameter, from which on the brake cur-
rent starts (parameter Brake diameter).
The parameter Pullback current sets the support current for the rewinder at
the minimum diameter of 25mm. When the diameter of the rewound label
web reaches the set value (Back diameter), the support current will be throt-
tled down to a mimimum.

P See parameter Pullback current  on page 87.
¯ If the label web is loose, while it is fed back under the printhead, decrease
this value in small steps. If the material is tightened too much, increase the
value in small steps.
XX mm Setting range: 0-120 mm; Default setting: 50 mm
