3. 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.
Noise Filter (NF)
Prevents external noise from the pow-
er 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 mo-
tor with this Magnetic Contactor.
Reactor (L)
Reduces harmonic current of the
main power.
For specifications, refer to the
downloaded Instruction Manual
from our Web Site.
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 shorting bar be-
tween 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 re-
generative resister, set up Parame-
ter No. 6C to 1 or 2.
• Connection to the Connector, CN X2
(connection to external components)
Handle lever
Use this for connector
connection. Store this
after connection for other
occasions.
(see page for connection.)
an external protective apparatus, such as
thermal fuse without fail.
For resistor value and capacity, refer to the
downloaded Instruction Manual from our Web Site.
Thermal fuse and thermostat are built in to the
regenerative resistor (Option). If the thermal
fuse is activated, it will not resume.
