System Configuration and Wiring
Wiring general view
Main circuit
Inverter
Motor
GND
No-fuse breaker (NFB)
or Earth leakage breaker
Used to protect the power line.
Interrupts the circuit in the case of excessive
current.
* Use an anti-harmonic earth leakage
breaker for the inverter.
Noise filter (NF)
Blocks noise from the power line.
Also reduces effect of noise from the servomotor.
Magnetic contactor (MC)
Turn main power to servomotor on/off.
Used with surge absorber mounted.
AC reactor (AC-L)
Reduces harmonic current of the power source.
Refer to “Option.”
DC reactor (DC-L)
Reduces harmonic current of the power
source.
Refer to “Option.”
Regenerative resistor
Improves regenerative control capacity.
For the regenerative brake circuit built-in type only.
Refer to “Option.”
