Three-Phase, 200 V Main Circuit - YASKAWA Sigma-II Series User Manual

1.3.2 Three-phase, 200 V Main Circuit

Power supply
Three-phase 200 VAC
R S T
Molded-case
circuit breaker
(MCCB)
Protects the power supply
line by shutting the
circuit OFF when
overcurrent is
detected.
(Refer to 5.8.9.)
Noise filter
Used to eliminate
external noise from the
power line.
(Refer to 5.8.10.)
Regenerative
resistor
Connect an external
regenerative resistor
to terminals B1 and B2
if the regenerative capacity
is insufficient.
(Refer to 5.8.6.)
Magnetic
contactor
Turns the brake power supply
ON and OFF.
Install a surge absorber.
(Refer to 5.8.11.)
Brake power supply
Used for a servomotor with a brake.
(Refer to 5.8.5.)
∗1
The main circuit positive-side terminal is only available
to use at three-phase 200 VAC, 6 kW SERVOPACK.
Do not use
∗2
Be sure to disconnect the lead between B2 and
B3, before connecting an external regenerative
registor to the SERVOPACK.
∗3
For connecting a DC reactor, refer to 6.4.8 DC Reactor
for Harmonic Suppression.
