System Configuration and Wiring
General Wiring Diagram
• Main Circuits
Non-Fuse Breaker (NFB)
Used to protect the power lines:
overcurrent will shut off the circuit.
Noise Filter (NF)
Prevents the external noise from the power
line, and reduces the effect of the noises gen-
erated by the servo motor.
Magnetic Contactor (MC)
Turns on/off the main power of the servo
motor.
Used together with a surge absorber.
Reactor (L)
Reduces the harmonic current in the
main power.
Terminals P and B
• In case of use under large regenerative
e n e r g y, c o n n e c t a n e x t e r n a l
regenerative discharge resistor to P
and B terminals.
<Notes>
Where residual-current-operated
protective device (RCD) is used for
protection in case of direct or indirect
contact. Only RCD of Type B is allowed
on supply side of this Electronic
Equipment (EE).
