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 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 a surge absorber together with this.
• Never start nor stop the servo motor 

Reactor (L)
Reduces harmonic current of the main 
power.

  the Connector, CN X1
  (connection to input power)
  <Remarks>
  Before turning the power 
  supply on, check whether 
  the input voltage is correct.

Handle lever
Use this for connector 
connection. Store this after 
connection for other occasions. 
(see page for connection.)

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 SV.Pr6C 
to 1 or 2.

Regenerative  resistor (optional)
<Remarks>
• When you use an external regenerative resister, 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.
