The permissible working area of the machine axes can be adapted to the partic-
ular machining situation using the “dynamic” working area limitation.
 SD43400: WORKAREA_PLUS_ENABLE (working area limitation active in
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.
 MD36100: POS_LIMIT_MINUS (1st software limit switch minus)
 MD36110: POS_LIMIT_PLUS (1st software limit switch plus)
 MD36120: POS_LIMIT_MINUS (2nd software limit switch minus)
