28 CHAPTER 3: SETTING INTO OPERATION
MOVE S2
Always refer to the electrical diagrams shipped with the bar feeder and placed in the electrical cabinet.
All wires for interface connections are numbered
All bar feeders are equipped with a power supply of +24 VDC.
Corresponds to the +24 V of the bar feeder. This power shall be used to connect the signals from the
lathe to the PLC.
All signals from the lathe to the PLC shall be powered by the +24 VDC of the bar feeder.
All signals from the bar feeder to the lathe shall be powered by the +24 VDC of the lathe.
For the other types of connections, please contact LNS, or their local representative.
This signal is part of a safety link (Emergency Stop circuit) of the bar feeder. XT8-XT9 corresponds to the
Emergency Stop signal of the lathe. If the circuit is open, the bar feeder will go into an Emergency Stop
mode.
When the lathe is in an Emergency Stop mode, or if the safety line of the bar feeder is interrupted, an
alarm will go off and the R1 relay of the bar feeder will be triggered (see description of the R1 relay,
below).
This signal is for checking the mode of the lathe clamping device (open), and is mainly used for the
feeding of a part, which takes place each time the clamp opens.
For safety reasons, wire a normally open contact, coming from the signal of the lathe clamp. A
signal must be selected.
This signal indicates that the lathe is in automatic cycle.
Should the lathe be equipped with a sub-spindle or of a Swiss type, should the part require multiple feeds,
this signal will be used as a load command from the lathe.
For safety reasons, and to prevent collisions between the part being transferred to the second spindle
and the newly loaded bar stock when there is a simultaneous loading, the lathe must control the loading
of a new bar.
This signal orders the forward movement of the feeding pusher and the bar, independently of the mode of
the lathe clamp.
As long as this signal is present, the signal of the foot switch to open and close the
clamping device of the lathe must be locked. The lathe should not start up in automatic
cycle as long as the clamping device does not grip the bar.
