7.2 Wiring Main Circuit
This section describes typical examples of main circuit wiring, functions of main circuit terminals, and the power
ON sequence.
7.2.1 Names and Functions of Main Circuit Terminals
* If using the main circuit power supply and the control power supply with DC power supply input, refer
to 7.2.3 Typical Main Circuit Wiring Examples (4) DC Power Supply Input for more information on
wiring.
• Do not bundle or run power and signal lines together in the same duct. Keep power and signal lines sepa-
rated by at least 300 mm (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 signal and encoder (PG) feed-
back 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 five minutes after turning power OFF because high voltage may still
remain in the SERVOPACK.
Make sure the charge indicator is turned OFF first before starting an inspection.
• Avoid frequently turning power ON and OFF. Do not turn the 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 the
power is turned ON. Frequently turning the power ON and OFF causes main power devices such as capacitors and
fuses to deteriorate, resulting in unexpected problems.
