Remarks
N3 is violated.
No limit is violated.
Only monitoring of the software limit switches still active.
Starting point violates C4
Preactivated C4 is not monitored. The specified distance can
be traversed completely.
Because _DLIMIT[1] = 2, the traversing distance is restricted
by the working area limitation.
Clearance to C4 is a total of 4 mm due to C2 and _DLIMIT[3].
Clearance C2 – N3 of 0.1 mm does not result in limitation of
the traversing distance.
