Preparation
Connecting Example of C to D-frame
• Apply the voltage designated on the nameplate
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).
• Wiring of Main Connector (XA)
Circuit Breaker (MCCB)
To protect power supply line from overload-
ing, 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) (to be supplied by customer)
Reduces harmonic current of the main
power.
• Wiring of Motor Connector (XB)
Pin P (6-pin), B (4-pin), and
RB (5-pin)
• RB and B to be kept shorted for
normal operation.
• When you connect an external
regenerative resistor, disconnect a
short circuit wire between RB and B,
then connect the external regenera-
tive resistor between P and B, set up
Pr0.16 to 1 or 2.
Note
This overall wiring diagram is a typical one. The pages that follow show wiring for specific
application. The wiring indicated with the broken line shall be provided only when required.

Wiring to Connector, XA
• Connection to input power
Wiring to Connector, XB
• Connection to external components
• When you use an external regenerative resistor,
install an external protective apparatus, such
as thermal fuse without fail.
• Thermal fuse and thermal protector 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.
