7.4. Signals from the lathe to the bar feeder
The lathe interface signal logic can be configured with service parameters. Only trained
personnel should change these settings.
a) 24V DC power supply
All the signals from the lathe were powered by the 24V DC from the bar feeder. When the corresponding
relay energized at the lathe, the 24V DC travels through corresponding contact and return to PLC. The
PLC hence receives lathe signals.
b) Emergency stop signals from the lathe
This contacts XT8 and XT9 are part of the bar feeder emergency stop loop of the bar feeder. When the
emergency circuit is open between XT8 and XT9, the bar feeder goes to EMERGENCY STOP MODE
and arise an e01 alarm and energize relay R1.
c) Lathe chuck signal (PLC input X11), terminal A1
Chuck signal is for confirming the status of lathe chuck (collet, clamping device). This signal initiates
feeding and bar change process of bar feeder by itself as well as combination with other signals.
The signal logic could be inverted by MODE 2 setup.
d) Lathe alarm (PLC input X12), terminal A2
This signal indicates that a lathe alarm is arising.
The signal logic could be inverted by MODE 3 setup.
e) M function (PLC input X13), terminal A3
This signal serves as an auxiliary signal for confirming chuck status. To activate this function, please refer
to MODE 7 for further information.
The signal logic could be inverted by MODE 4 setup.
f) Spare signal (PLC input X14), terminal A4
This signal is not connected in the universal interface.
7.5. 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 lathe.
The lathe pedal should not be operational as long as the feeding pusher feed command signal is
present.
Whenever possible, it is advisable to interlock lock the manual command for opening the lathe
clamping device while the feeding pusher command signal is on.
If the lathe is in the Emergency Stop mode, the bar feed system must also be under the
Emergency Stop mode, and vice-versa.
If the bar feed system generates an alarm, the lathe must go into alarm mode. The feeding
pusher feed command signal must go off, the spindle axis and rotation must stop.
