Panasonic A4P Series System Configuration and Wiring, Pin RB1 6-pin, RB2 4-pin, RB3 5-pin

System Configuration and Wiring

Overall Wiring (Connecting Example of C-frame, 3-phase)

• Wiring of the Main Circuit (see P.34, 35.)

(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.

•Connection to ￿

the Connector, CN X1￿ (connection to input power)￿

<Remarks>￿

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

L1 (Pin-5)

L2 (Pin-4)

L3 (Pin-3)

L1C (Pin-2)

L2C (Pin-1)

Pin RB1 (6-pin), RB2 (4-pin), and

RB3 (5-pin)￿

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.

•Connection to the Connector, CN X2￿ (connection to external components)

RB1 (Pin-6)

RB2 (Pin-4)

Handle lever￿

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

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.
