 Wiring
CAUTION
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Securely tighten the cable connector screws and securing mechanism.
If the connector screws and securing mechanism are not secure, they may loosen
during operation.
• Use cables with a radius, heat resistance, and flexibility suitable for the
system.
• If the SERVOPACK malfunctions, turn OFF the main circuit’s power supply
of the SERVOPACK.
The continuous flow of a large current may cause fire.
• Use a noise filter to minimize the effects of electromagnetic damage.
Failure to observe this caution may result in electromagnetic damage to electronic
devices used near the SERVOPACK.
• Do not connect a commercial power supply to the U, V, or W terminals for
the linear servomotor connection.
Failure to observe this caution may result in injury or fire.
• Securely connect the main circuit power supply terminals and linear servo-
motor connection terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run the main circuit cables together with the I/O signal
cables or the linear scale connection cables in the same duct. Keep them
separated by at least 30 cm.
Failure to do so may result in malfunction.
• Use shielded twisted-pair wires or multi-core shielded twisted-pair wires for
I/O signal cables and the linear scale connection cables.
• The maximum cable length is 3 m for the I/O signals, 20 m for the linear
servomotor main circuit, 20 m for the serial converter unit, 15 m for the lin-
ear scale, 15 m for the hall sensor, and 10 m for control power supply
cables for the SERVOPACK with a 400-V power supply (+24 V, 0 V).
• Do not touch the power terminals while the charge indicator is ON after
turning power OFF because high voltage may still remain in the SERVO-
PACK.
Make sure the charge indicator is off first before starting wiring and inspection.
• Be sure to observe the following precautions when wiring the SERVO-
PACK main circuit terminals has been completed.
• Do not turn ON the power to the SERVOPACK until all wiring including main
circuit terminals has been completed.
• Remove detachable main circuit terminals from the SERVOPACK prior to wir-
ing.
• Insert only one main circuit cable per opening in the main circuit terminals.
• Make sure that no part of the core wire comes into contact with (i.e., short-cir-
cuit) adjacent wires.
• Do not connect the SERVOPACK for 200 V directly to a voltage of 400 V.
The SERVOPACK will be destroyed.
• Always use the specified power supply voltage:
Failure to observe this caution may result in fire or product failure.
