5.4 CAM BOX - TIMING
If the feeder is equipped with a cam box, each cam should be timed to its own microswitch. The
timing procedure is as follows.
MICROSWITCH FUNCTION
S90 - Bar feed enabling signal
It controls the bar feeding motor start/stop. It must be operated at each collet opening. In
addition, it also controls operation of the bar/headstock synchronizing device.
S91 - Bar change enabling
It signals lathe collet opening/closing to the feeder.
It determines the camshaft stop position at bar end.
S92 - Feed stop enabling
Only used in sliding headstock lathes. It disables the feed thrust during any operations
requiring headstock return with a closed collet.
S99 - Camshaft stop
It determines the camshaft stop position when there is no thread (connected in series with a
microswitch or relay located on the lathe).
