Overall Wiring (Connecting Example of E-frame)

• 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 P, B1 and B2...
B1 and B2 to be kept shorted for
normal operation.
When the capacity shortage of
the regenerative resister is
found, disconnect a short bar
between B1 and B2, then con-
nect the external regenerative
resister between P and B2.
Install an external regenera-
tive resister on incombustible
material, such as metal. Follow
the same wiring connection as
the above.
When you connect an external
regenerative resister, set up
Parameter No. 6C to 1 or 2.
• Connection
with input
power supply
• Connection to external
components

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.
