the feed-motor is switched to move slowly until it reaches the limit switch and is
switched OFF (via the ladder program). At this moment a new object is placed in
position again. At this moment the feed-motor stays switched OFF for as long as
the proximity switch has detected a new object, initiating the whole cycle again.
The limit switch is connected to Digital Input I0 which is assigned function 05 (i.e.
Reset Rising Edge). Activation of the limit switch when the drill-motor is in the
home position causes Counter 1 to be reset and the feed-motor to be switched to
its initial state (slow/forward). An Output Reset Pattern (m+61, m+62) has been
defined to switch the feed-motor to its initial state.
The Machine Number of the High-speed Counter Unit is 0. The High-speed Coun-
ter is allocated 40 CIO-words starting from CIO 2000 (n = CIO 2000 + 0 x 10) and
400 DM-words starting from D 20000 (m = D 20000 + 0 x 100). The Comparison
Data of Counter 1 is stored in EM starting from EM 1500. To configure the Unit the
following DM-settings must be made.

+S et Pattern: Set Digital Output O0 (i.e. change speed of feed-motor M1 from
slow (=0) to fast (=1)) in the posit ive (=+) counting direction
+Res et Pattern: no outputs are reset at the crossing of CV0 in the positive
cou nting direction
-Set Pattern: no out puts are setat the crossing of CV0 in the negative counting
direction
-Res et Pattern: Reset Digital Output O0 (i.e. change speed of feed-motor M1
from fast (=1) to slow (=0)) in t he negative (=-) counting direction
