(3) How to use the control circuit terminal block (Phoenix Contact make)
1) Termination of the cables
Solid wire:
the cable can be used as it is. (Cable
size: 0.2 to 2.5mm
Twisted wire: Use the cable after stripping the sheath and twisting the core. At this

Main circuit power input terminals
Supply L1, L2 and L3 with the following power:
For single-phase 230VAC, connect the power supply to L1/L2
and leave L3 open.
Power supply
3-phase 200 to 230VAC, 50/60Hz
(Note) Single-phase 230VAC, 50/60Hz
Single-phase 100 to 120VAC, 50/60Hz
Note: Cannot be used for combination with the servo motor HC-SF52.
Control circuit power input terminals
Supply L11 and L21 with the following power:
Power supply
Single-phase 200 to 230VAC, 50/60Hz
Single-phase 100 to 120VAC, 50/60Hz
L11 and L21 should be in phase with L1 and L2, respectively.
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.
Servo motor power output terminals
Connect to the servo motor power supply terminals (U, V, W).
Do not connect.
Ground terminal
Connect this terminal to the protective earth (PE) terminals
of the servo motor and control box for grounding.
After the sheath has been stripped,

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
Alternatively, a bar terminal may be used to put the wires together.
