3. System Configuration and Wiring
Overall Wiring (Terminal block type)
Connecting Example of H-frame, 200 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.

Remarks
• When you use an external
regenerative resistor, install an
external protective apparatus, such
as thermal fuse without fail.

value, use a current-limiting
device (e.g. current-limiting fuse,
current-limiting circuit breaker or
transformer).

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 brake and the 24 VDC
power supply for regenerative resistor),
insulation is required.
Do not connect these terminals to the
-phase
same power supply.
Pin B1and B2
• When you connect an external regenera-
tive resistor, connect the external
regenerative resistor between B1 and B2,
set up Pr0.16 to 1 or 2.
Pin DB1 and DB2
• When installing an external dynamic brake
resistor, connect the magnetic contactor
(for controlling) for external dynamic brake
to between LIC and DB1.
Remarks
• The voltage applied across DB1 and
DB2 must be 300 VAC or below or 100
VDC or below.
Pin NC
• Do not connect anything.
