3.2.79.2 Compare actual position with values stored
l PSAVE−ON = HIGH:
– The inputs PSAVE−MPOS and PSAVE−ACTPOS are compared with the stored values. The
deviations are output at PSAVE−M−DIFF or PSAVE−ACT−DIFF.
PSAVE − M − DIFF

– The evaluation of one of the channels can be suppressed by means of a code. In this case,
PSAVE−DIFF = 0
l
PSAVE−ON = LOW:
– The outputs PSAVE−DIFF = 0.
3.2.79.3 Output of status signals
The digital outputs are set according to the difference calculated (PSAVE−DIFF) if PSAVE−ON = HIGH.
l
A hysteresis can be set via code:
– for MPOS C1430/1 in m−units
– for ACTPOS C1430/2 in s−units
l
As long as −DIFF <
±
C1430/x:
– −M−HI = LOW
– −M−LO = LOW
– ACT−HI = LOW
– ACT−LO = LOW
l
If −DIFF pos. and > +C1430/x
– −M−LO = HIGH and/or
– ACT−LO = HIGH
l If −DIFF neg. and < −C1430/x
– −M−HI = HIGH and/or
– ACT−HI = HIGH
l
If one channel is suppressed through code C1431, the outputs of the corresponding channel
are set to LOW.
