General Wiring Diagram
■ Main Circuits
Non-Fuse Breaker (NFB)
Used to protect the power lines:
overcurrent will shutoff the
circuit.
Noise Filter (NF)
Prevents the external noise from the
power line, and reduces the effect of the
noises generated 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 in the main
power.
Motor cable:
・ Without a brake
・ With a brake
Terminals P, B1 and B2
・ N o r m a l l y k e e p B 1 a n d B 2
shorted.
・ If the capacity of the internal
regenerative discharge resistor
is not enough, disconnect be-
tween B1 and B2, and
connect an external regenerative
discharge resistor to P and B2
terminals.
