5.4 CAM BOX - TIMING
If the bar 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 feeding 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 synchronization device.
S91 - Bar change enabling
It signals lathe collet opening/closing to the bar feeder.
It determines the camshaft stop position at bar end.
S92 - Feeding stop enabling
Only used in sliding headstock lathes. It disables the bar feeder feeding thrust during any
operations requiring headstock return with 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).
