ELECTRICAL EQUIPMENT
SERVICE MANUAL – QL Servo S3-T
CONNECTIONS
POWER SUPPLY
Voltage: 200-480 V, 50/60 Hz + Ground (± 10%)
Maximum current: 1 A
In the case where the voltage supplied by the lathe does not match that provided for the barfeed, the transformer T1 must be
adapted.
The LNS bar feed systems are equipped with their own thermal protection systems (breakers, thermal relays and fuses, etc.).
The power supply for the bar feed system should be connected to the output of a breaker mounted in the electrical control box
of the lathe (10 A max.).
For the wiring inside the lathe, the section of the cables should be at least 1.5 mm
2
(AWG 16 ) .
SIGNALS FROM THE LATHE TO THE BARFEED SYSTEM
Always refer to the electrical diagrams shipped with the bar feed system and placed in the electrical cabinet. Although an
example of an interface diagram is provided, the diagram for the interface corresponding to your device, essential when making
the electrical connection, is located inside the electrical cabinet.
a) 24 V dc power supply
Corresponds to the +24 V of the bar feed system. 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 V dc of the bar feed system.
•
All signals from the bar feed system to the lathe shall be powered by the +24 V dc of the lathe.
For the other types of connections, please contact LNS S.A. or their local representative.
b) "EMERGENCY STOP" signal of lathe XT8-XT9
This signal is part of a safety link (Emergency Stop circuit) of the bar feed system. XT8-XT9 corresponds to the Emergency
Stop signal of the lathe. If the circuit is open, the bar feed system will go into an Emergency Stop mode.
When the lathe is in an Emergency Stop mode, or if the safety line of the bar feed system is interrupted, an alarm will go off
and the R1 relay of the bar feed system will be triggered (see description of the R1 relay, below).
c) Lathe clamp signal (PLC input A1)
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.
INFO
For safety reasons, wire a normally open contact, coming from the signal of
the lathe clamp. A clamp open signal must be selected.
d) Lathe in automatic cycle (PLC input A2)
This signal indicates that the lathe is in automatic cycle.
e) Load command (PLC input A3)
Should the lathe be equipped with a sub-spindle or the lathe is of twin spindle 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.
f) Feeding pusher control (PLC input A4)
This signal orders the forward movement of the feeding pusher and the bar, independently of the mode of the lathe clamp.
