7.5.7 Impact of the inhibit signal
The impact of the inhibit signal on the start signal is in-
fluenced by
MACHINE SETUP > On inhibit enter and MACHINE
SETUP > On inhibit leave
. Combining the settings of the two
functions has different effects.
To simplify the description in the following, abbrevia-
tions are used for the settings (see table). „A“ refers to
the rising slope, „B“ refers to the dropping slope of the
inhibit signal.
[166] Example for setting combination A1B1 and A1B2.
– A = relative position of the product sensor at the time
of
rising signal slope
– A´ = relative position of the dispensing edge at the
time of
rising signal slope
– B = relative position of the product sensor at the time
of
dropping signal slope
– B´ = relative position of the dispensing edge at the
time of
dropping signal slope

MACHINE SETUP >
On inhibit enter
„Do saved starts“ A1 Low-high Queue is processed
„Del saved starts“ A2 Queue is deleted
MACHINE SETUP >
On inhibit leave
„Do saved starts“ B1 High-Low Queue is processed
„Del saved starts“ B2 Queue is deleted
