Overall Wiring (Connecting Example Of E-Frame) - Panasonic minas a4 series Instruction Manual

System Configuration and Wiring

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.
(see P.309)
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
with this Magnetic Contactor.
(see P.321)
Reactor (L)
Reduces harmonic current of the main
power.
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 connect the external
regenerative resister between P
and B2.
Install an external regenerative
resister on incombustible material,
such as metal . Follow the same
wiring connection as the above.
• When you connect an external
regenerative resister,
Parameter No. 6C to 1 or 2.

(see P.32, 33 and 309.)
(see P.32 and 33.)
set up
• Connection with input
power supply
• Connection to external components
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 re-
generative resistor (Option). If the thermal fuse is
activated, it will not resume.
