Ground (earth)

• Connection with input 
   power supply

  <Remarks>
  Before turning the power 
  supply on, check whether 
  the input voltage is correct.

• Connection to external components

B1 and B2 to be kept shorted for nor-
mal operation. 

• When the capacity shortage of the 

regenerative resister is found, dis-
connect a short bar between B1 
and B2,  then connect the external 
regenerative resister  between P 
and B2.

   Install an external regenerative re-

sister on incombustible material, 
such as metal. Follow the same wir-
ing connection as the above. 

• When you connect an external re-

generative resister, set up SV.Pr6C 
to 1 or 2.

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.

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.
