Panasonic A4P Series Overall Wiring Connecting Example of E-frame, Pin P, B1 and B2

System Configuration and Wiring

Overall Wiring (Connecting Example of E-frame)

• Wiring of the Main Circuit (see P.36, 37.)

(see P.32, 33 and 177.)

Circuit Breaker (NFB)￿

Use the circuit breaker matching capacity of the power source to protect the power lines.￿

￿

(see P.177 , 178.)

Noise Filter (NF)￿

Prevents external noise from the power lines. And reduces an effect of the noise generated by the servo driver. ￿

￿

(see P.32, 33.)

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 with this Magnetic Contactor. ￿

￿

(see P.189.)

Reactor (L)￿

Reduces harmonic current of the main power.

Pin P, B1 and B2...￿

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.

•Connection with input ￿ power supply￿

<Remarks>￿

Before turning the power ￿ supply on, check whether ￿ the input voltage is correct.

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.
