*
Used for a
servomotor
with a brake.
Used for a
regenerative unit.
Noise filter
Used to eliminate suppress noise
from power lines for CE marking
requirements.
Molded-case circuit breaker
To protect the equipment and wiring,
always connect a molded-case circuit
breaker.
Magnetic contactor
Used to turn OFF the servo
power supply when using a
regenerative unit or in case
of emergency.
Power supply
Single-phase 200 VAC
Regenerative unit
Used if regenerative
energy is high.
AC reactor
Used for a power
supply harmonic
suppression.
Fuse
To protect the
equipment, always
install fuses.
Surge protector
To protect the
system from
lightening surge.
Never open the protective cover for
the connector.
Do not use the connector since the
connector is reserved for adjustment
by the manufacturer.
If the connector is used, a
SERVOPACK failure may result.
CAUTION
Correctly connect the
connectors CNA and
CNB.
Incorrect wiring may
result in electric shock,
injury, or damage to
the equipment.
After wiring, install the
connectors as explained
in 3.8 Wiring the Power
Supply/Regenerative
Unit Connector (CNA)
and 3.9 Wiring the
Servomotor Main Circuit
Cable Connector (CNB).
