System Configuration and Wiring

Overall Wiring (Connecting Example of C-frame, 3-phase)

• Wiring of the Main Circuit
Circuit Breaker (NFB)
Use the circuit breaker matching capacity
of the power source to protect the power
lines.
(see P.309)
Noise Filter (NF)
Prevents external noise from the power
lines. And reduces an effect of the noise
generated by the servo driver.
Magnetic Contactor (MC)
Turns on/off the main power of the servo
driver.
Use a surge absorber together with this.
• Never start nor stop the servo motor
with this Magnetic Contactor.
(see P.321)
Reactor (L)
Reduces harmonic current of the main
power.
Pin RB1 (6-pin), RB2 (4-pin), and
RB3 (5-pin)
• RB2 and RB3 to be kept shorted for
normal operation.
• When the capacity shortage of
the regenerative resister is found,
disconnect a
between RB2 and RB3, then
connect the external regenerative
resister between RB1 and RB2.
(Note that no regenerative resister
is equipped in Frame A and B type.
Install an external regenerative
resister on incombustible materi-
al, such as metal. Follow the same
wiring connection as the above.)
• When you connect an external
regenerative resister,
Parameter No. 6C to 1 or 2.

• Connection to the Connector, CN X2
(connection to external components)
Regenerative resistor (optional)
<Remarks>
When you use an external regenerative resister, install
an external protective apparatus, such as thermal fuse
without fail.
Thermal fuse and thermostat are built in to the regenera-
tive resistor (Option). If the thermal fuse is activated, it
will not resume.
• Connection to
the Connector, CN X1

Use this for connector
connection. Store this after
