3. System Configuration and Wiring
Overall Wiring (Terminal block type)
Connecting Example of G-frame, 400 V type
• Wiring of Main Connector
Circuit Breaker (MCCB)
To protect power supply line from
overloading, install a wiring circuit
breaker rated to the capacity of the
power supply.
Noise Filter (NF)
Removes 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 coil surge suppression units
together with this.
• Never start nor stop the servo
motor with this Magnetic Contactor.
Reactor (L)
Reduces harmonic current of the main
power.
Connection to external components
Regenerative resistor (optional)
Remarks
• When you use an external regenerative
resistor, install an external protective
apparatus, such as thermal fuse without
fail.
• Thermal fuse and thermostat are built in to the
regenerative resistor (Option). If the thermal
fuse is activated, it will not resume.
• Mount the regenerative resistor on
incombustible material such as metal.
Note
The wiring indicated with the broken line shall be
provided only when required.
Mains • Apply the voltage desig-
nated on the nameplate
Residual
current device
from the power source.
Symmetric current should be
5000 Arms or below.
If the short-circuit current on the
power source exceeds this
value, use a current-limiting
device (e.g. current-limiting fuse,
current-limiting circuit breaker or
transformer).

Pin B1 and B2
• When you connect an external regenera-
tive resistor, connect the external regen-
erative resistor between B1 and B2, set up
Pr0.16 to 1 or 2.
Pin DB1, DB2, DB3 and DB4
･ Normally, leave DB3 and DB4 short-
circuited.
･ To connect the external dynamic brake
resistor, refer to "Dynamic Brake" on
P.B48. Do not use the external dynamic
brake resistor together with the built-in
resistor.
Pin NC
• Do not connect anything.

Short bar (DB3-DB4)
Charge lamp (LED)
Do not make displacement, wiring or
inspection while the LED is lit - cause of
electric shock.
Remarks
• X1 to X7 are used for the
secondary circuit. To connect
these terminals to the primary
power supply (particularly, the 24
VDC power supply for control and
the 24 VDC power supply for
brake), insulation is required.
Do not connect these terminals to
the same power supply.
