7.2.4 Wiring the FG wire of the BUS cable
1 To connect the QCPU, motion controller CPU (Q series) and GOT
The cable for connection to the QCPU, motion controller CPU (Q series) does not have a FG wire that
needs to be grounded.
2 To connect QnACPU, ACPU, motion controller CPU (A series) and GOT
When using GT15-C FXSS-1 or GT15-C BS, ground the FC wires as shown in the figure below.
(1) GT15-C EXSS-1
(2) GT15-C BS
For both GOTs, provide the same grounding as described in the section (1) above to both GOTs.
1 Ground the FG terminal of the power supply terminal block on the GOT.
2 FG wires on GT15-C BS must be 28 cm or less.
3 Leave the FG ground wire on GT15-EXCNB unconnected.
4 Connect the FG wire on GT15-C BS on the GOT side to the FG terminal of
the power supply terminal block on the GOT.
5 Connect the FG wire on GT15-C BS on the PLC side to the FG terminal of the
power supply terminal block on the PLC.
6 Connect the LG and FG terminals on the terminal block, and provide a single
grounding point for them.
