Power supply
Single-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 4.4.8 Molded-
case Circuit Braker (MCCB).)
Noise filter
Used to eliminate
external noise from the
power line.
(Refer to 4.4.9.)
Regenerative
resistor
Connect an external
regenerative resistor
to terminals B1 and B2
if the regenerative capacity
is insufficient.
(Refer to 4.4.6 External
Regenerative Resistor.)
Magnetic contactor
Turns the brake power supply
ON and OFF.
Install a surge protector.
(Refer to 4.4.10 Magnetic Contactor.)
Brake power supply
Used for a servomotor with a brake.
(Refer to 4.4.5 Brake Power Supply
Unit.)
SGDS-
Magnetic
contactor
Turns the servo
ON and OFF.
Install a surge
protector.
(Refer to
4.4.10 Magnetic
Contactor.)

1.3 Examples of Servo System Configurations
Notes: 1. For single-phase 200V 800W SERVOPACKS,
the terminal L3 is not used. Do not connect.
2. Remove the lead wire between the terminals
B2 and B3 on the SERVOPACK before
connecting an external regenerative resistor
to the SERVOPACK.
3. For connecting the AC/DC reactor, refer to
5.4.5 AC/DC Reactor for Harmonic Suppression.
