7.2 TEACHING BOX INTERFACE
Overview
If a teaching box interface option is specified, the JD36A or JD36B
connector of the motherboard can be used as a teaching box interface.
The parameter No.15640 specifies which connector to be used.
The teaching box reads the coordinates of the taught position from the
CNC, converts them to NC commands, then registers the commands in
CNC program memory. The teaching box is not supplied by FANUC;
it must be manufactured or supplied by the machine tool builder. This
section describes the specifications of the interface used to connect the
teaching box.
Interconnection
Connect as follows:
Mother
-board
<1> Prepare a relay circuit on the operator's panel, and receive signals
from the teaching box at this relay circuit.
<2> Separate the signals received at the relay circuit into two groups.
Direct one group (RS-232C interface signals) to the JD36A or
JD36B connector of the motherboard of the CNC, and the other
group (I/O signals) to I/O cards through the operator's panel
circuit.
<3> Prepare a power supply for the teaching box on the operator's
panel and supply power to the teaching box through the relay
circuit.
<4> It is recommended that an emergency stop button be installed on
the teaching box. This emergency stop button should be handled
together with the emergency stop button on the operator's panel.
<5> Teaching box exclusive right signal (input) TBES <G226#6>
The CNC can always communicate with a teaching box if it is
available. If the CNC is started with no teaching box connected,
or if the PMC, or macro executor tries to use the I/O interface, it
is necessary to switch the exclusive right.
