(3) How to use the control circuit terminal block (Phoenix Contact make)
1) Termination of the cables
Solid wire: After the sheath has been stripped,
the cable can be used as it is. (Cable
size: 0.2 to 2.5mm
2
)
Twisted wire: Use the cable after stripping the sheath and twisting the core. At this
time, take care to avoid a short caused by the loose wires of the core
and the adjacent pole. Do not solder the core as it may cause a con-
tact fault. (Cable size: 0.2 to 2.5mm
2
)
Alternatively, a bar terminal may be used to put the wires together.

Protective earth (PE)
Ground terminal
Connect this terminal to the protective earth (PE) terminals
of the servo motor and control box for grounding.
Regenerative brake option connection terminals
C and D are factory-connected.
When using the regenerative brake option, always remove
wiring from across P-D and connect the regenerative brake
option across P-C.
