7.6.1
Wiring FG cable of bus connection cable
This section describes wiring of the FG cable when a PLC CPU is connected to the GOT.
Cable connected to the PLC CPU
Do not install the connection cable together with the main circuit lines (high voltage,
large current) or I/O signal lines.
1
When connecting QCPU or motion controller CPU (Q series) to the GOT
• Grounding of the FG cable for QCPU and motion controller CPU (Q series) is not necessary since they
have no FG wire.
2
When connecting QnACPU, ACPU, or motion controller CPU (A series) to the GOT
• When using GT15-C EXSS-1 or GT15C BS, perform the grounding in the following steps.
(1) GOT terminal block
The terminal block layout of a GOT differs depending on the model.
Before wiring, check the terminal layout of the GOT to be used.
(2) Ground cables
Up to two ground cables can be connected to the LG and FG terminals of the
GOT respectively.
For three or more ground cables, connect the third or later ground cables to the
LG terminal.
