the positive direction)
SD43410: WORKAREA_PLUS_ENABLE (working area limitation active in
the negative direction)
SD43420: WORKAREA_LIMIT_PLUS (working area limitation plus)
SD43430: WORKAREA_LIMIT_MINUS (working area limitation minus)
Alarm: “10630 Axis reaching operating range limit +/–”
Alarm: “10631 Axis is at operating range limit +/– (JOG)”
Alarm: “10730 Progr. end point is behind operating range limit +/–”.
Two software limit switch pairs are provided per machine axis. The active soft-
ware limit switch pair is selected in the PLC.
