Failure to observe this caution may result in injury or fire.
• Securely connect the power supply terminal screws and motor output terminal screws.
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 signal
lines separated by at least 30 cm (11.81 in).
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for signal and encoder
(PG) feedback lines.
The maximum length is 3 m (118.11 in) for reference input lines and is 20 m (787.40 in) for PG feedback
lines.
• Do not touch the power terminals for 5 minutes after turning power OFF because high voltage may
still remain in the SERVOPACK.
Make sure the charge indicator is out first before starting an inspection.
• 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 like capacitors
and fuses to deteriorate, resulting in unexpected problems.
• 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.
An incorrect voltage may result in burning.
