Wiring
CAUTION
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or
malfunction.
• Do not connect a commercial power supply to the U, V, or W ter-
minals for the servomotor connection.
Failure to observe this caution may result in injury or fire.
• Securely connect the main circuit terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run the servomotor main circuit cables together
with the I/O signal cables or the encoder cables in the same duct.
Keep the servomotor main circuit cables separated from the I/O
signal cables and encoder cables by at least 30 cm.
Placing these cables too close to each other may result in malfunction.
• Use shielded twisted-pair cables or screened unshielded twisted-
pair cables for I/O signal cables and the encoder cables.
• The maximum wiring length is 3 m for I/O signal cables, 50 m for
servomotor main circuit cables and encoder cables, and 10 m for
power supply cables.
• Install the battery in the battery unit of the encoder cable with a
battery unit.
• Voltage remains in the SERVOPACK even after the power supply
is turned OFF. To prevent electric shock, do not touch the input
terminals for the main circuit power supply or those for the con-
trol power supply.
Before wiring or inspections, confirm that the SERVOPACK has com-
pletely discharged.
• Be sure to observe the following precautions when wiring the
SERVOPACK main circuit terminal blocks.
• Do not turn the SERVOPACK power ON until all wiring, including
the main circuit terminal blocks, has been completed.
• Remove detachable power supply input connectors or motor connec-
tors from the SERVOPACK before wiring.
• Make sure that the wiring for both the main circuit power supply
and control power supply is correct.
Incorrect wiring may cause damage.
