6-8 Application Examples
The following is a brief description of the application.
•
The drill (O:1/1) and feed motors (O:2/0 and O:2/1) are off. The
drill is in the home position (limit switch is open).
•
The feed motor (O:2/0) moves forward in the slow speed until
count 49.
•
At count 50, the drill moves forward in the fast speed (O:1/2).
•
At count 10,000 the drill bit begins turning (O:1/1).
•
At count 10,250 the feed motor returns to the slow speed
(O:1/2).
•
At count 10,999 the Forward Stop output disables the forward
motion of the feed motor. (O:2/0). The drill motor (O:1/1) is still
turning.
•
The Forward Stop range begins at count 11,000. The user
program detects that the Forward Stop range has been entered
using Soft Output bit 7. The Soft Output is set using the Output
Data File (O:1/7) and is monitored in the Output Status field
(I:1.4/15). The feed motor returns to the slow speed (O:1/2),
reverse direction (O:2/1).
•
At 10,249 counts, the feed motor enters the fast speed (O:1/2).
•
At count 9,999, the drill motor turns off (O:1/1).
•
At count 49 the feed motor enters the slow speed (O:1/2).
•
At count 0 the limit switch opens, the feed motor (O:2/1) stops,
and the drill moves to its home position.
