Three-Phase (400V) Main Circuit Specifications

Power supply for Brake
Supplied by 100V or 200V
ac ac
Supplied by 24V for
DC
servomotor with 24V brake.
DC
Molded-Case Circuit
Breaker (MCCB)
Protects the power
line by shutting
OFF the circuit
when overcurrent
is detected.
Noise Filter
Used to eliminate external
noise from the power line.
Magnetic Contactor
HI Series
Turns the servo
ON and OFF.
Install a surge
suppressor on
the magnetic
contactor.
Brake Power Supply
Used for a servomotor
with a brake.
Regenerative Resistor
Connect an external regenerative
resistor to terminals B1 and B2
if the regenerative capacity
is insufficient.
For 6kW or higher, an external
resistor is required.
