3. System Configuration and Wiring
Overall Wiring (Terminal block type)
Connecting Example of H-frame, 400 V type
• Wiring of Main Connector
Circuit Breaker (MCCB)
To protect power supply line from
overloading, install a wiring circuit breaker
rated to the capacity of the power supply.
Noise Filter (NF)
Removes 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 coil surge suppression units together
with this.
• Never start nor stop the servo motor
with this Magnetic Contactor.
Reactor (L)
Reduces harmonic current of the main
power.
