6.7 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.
6.7.1 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.
6.7.2 When connecting QnACPU, ACPU, or motion
controller CPU (A series) to the GOT
• When using GT15-C
grounding in the following steps.
(1) GOT terminal block
The terminal block layout of a GOT differs depending on the
Before wiring, confirm the terminal layout of the GOT to be
(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.
