The press must have
an automated overrun traverse control for the first stroke. If not, it can be realised by
the AKAS®-...F and a cam controller or by the Fiessler AMS-system . Before the initial start-up, the overrun tra-
verse must be checked either by using the test rod (see page 9) or by using an Overrun Traverse measuring
device.
(upon customer's request, Fiessler Elektronik will perform the Overrun Traverse Measuring on the customer's machine.)
If the results of 10 consecutive measurements are larger than 15mm (AKAS®-LC...), 14mm (AKAS®-II...) bzw.
13mm (AKAS®-3...) , the fast speed must be reduced.
According to the induvidual overrun traverses of each machine, 8 different distances Z
(=gap betrween uppermost receiver ele-
ment and bending punch, see Fig. 19/1 u. Fig. 19/2)
can be programmed via 3 dis switches at the support. The adjustment to the re-
spective selected distance is carried out automatically. (s. chapter 5.7 (Adjustment of the distance of the AKAS® from
the bending punch). Fiessler delivers the system pre-adjusted "A".
