„ Wiring
• Provide the specified clearances between the SERVOPACK and the control panel or with
other devices.
Failure to observe this caution may result in fire or malfunction.
• SERVOPACK is precision equipment. Do not apply any strong impact.
Failure to observe this caution may result in malfunction.
• Do not connect a three-phase power supply to the U, V, or W output terminals.
Failure to observe this caution may result in injury or fire.
• Securely connect the power supply terminals, regenerative unit connection terminal, and
motor main circuit cable terminals.
Failure to observe this caution may result in fire.
• Do not bundle or run power and signal lines together in the same duct. Keep power and sig-
nal lines separated by at least 30 cm (11.81 in).
Failure to observe this caution may result in malfunction.
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for I/O signal cable
and encoder cable.
The maximum length is 3 m (118.11 in) for reference input lines and is 20 m (787.40 in) for PG feed-
back lines.
• Do not touch the power terminals for five minutes after turning the power supply LED (PWR)
are OFF because high voltage may still remain in the SERVOPACK.
• Avoid frequently turning power ON and OFF. Do not turn power ON or OFF more than once
per minute.
Since the SERVOPACK has a capacitor in the power supply, a high charging current flows for 0.2
seconds when power is turned ON. Frequently turning power ON and OFF causes main power
devices such as capacitors and fuses to deteriorate, resulting in unexpected problems.
• Observe the following precautions when wiring connectors for power supply/regenerative
unit and for motor main circuit cable.
• Remove the connectors from the SERVOPACK prior to wiring.
• Insert only one wire per terminal on the connectors.
• Make sure that the core wire is not electrically shorted to adjacent core wires.
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Always use the specified power supply voltage.
Failure to observe this caution may result in damage to the SERVOPACK. For details on the power
supply voltage, refer to 8.1 Specifications.
