The permissible working area of the machine axes can be adapted to the partic-
ular machining situation using the ”dynamic” working area limitation.
S SD43400: WORKAREA_PLUS_ENABLE (working area limitation active in
the positive direction)
S SD43410: WORKAREA_PLUS_ENABLE (working area limitation active in
the negative direction)
S SD43420: WORKAREA_LIMIT_PLUS (working area limitation plus)
S SD43430: WORKAREA_LIMIT_MINUS (working area limitation minus)
S Interrupt: ”10630 Axis reaching operating range limit +/--”
S Interrupt: ”10631 Axis is at operating range limit +/-- (JOG)”
S Interrupt: ”10730 Progr. end point is behind working area limitation +/ --”
Two software limit switch pairs are provided per machine axis. The active soft-
ware limit switch pair is selected in the PLC.
S MD36100: POS_LIMIT_MINUS (1st software limit switch minus)
S MD36110: POS_LIMIT_PLUS (1st software limit switch plus)
S MD36120: POS_LIMIT_MINUS2 (2nd software limit switch minus)
