c) R2 loading cycle completed signal relay
When the pusher is stopped based on servo encoder setup, it will energize Relay R2. Generally this signal is for confirming
the bar stock hit the stopper during feeding so that the lathe chuck should closed accordingly.
d) R3 end of bar signal relay
When the pusher reaches END OF BAR position during feeding, relay R3 energizes. This signal is used to indicate that the
rest bar stock length is not long enough to machine a complete part according to part length setup value.
Refer to operation parameter P06 and service parameter MODE 11, 12, 13 for further information.
e) R4 automatic mode relay
This signal is present as soon as the bar feed system is in automatic cycle (Auto Ready + Auto Start).
f) R5 INCHING relay
This relay energizes under
circumstances below:

position.
2 The moment when the LONG
pusher leaves the home
position for TOP CUT. The moment the LONG pusher
stopped after arriving at TOP
CUT position.
3 The moment when the lathe
chuck opens during machining. The moment the LONG pusher
is stopped after it has fed the
part length.
Refer to service parameter MODE 16 for more information.
RECAPITULATION OF SAFETY INSTRUCTIONS RELATED TO THE INTERFACE
•
The lathe foot switch for opening the lathe clamping device should not be operational during the automatic cycle of the
