3.2.79 Position memory (PSAVE)
3−256
l
EDSVS9332K−EXT EN 4.0
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.
PSAVEMDIFF + stored value *
{
PSAVEMPOS
}
PSAVEACTDIFF + stored value *
{
PSAVEACTPOS
}
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.
