3.3. Main Circuit Wiring

This section shows typical examples of main circuit wiring for XtraDrive
Series servo products, functions of main circuit terminals, and the power ON
sequence.
Observe the following precautions when wiring.
Do not bundle or run power and signal lines together in the same duct. Keep power and
signal lines separated by at least 30cm (11.81 in).
Not doing so may cause a malfunction.
Use twisted pair wires or multi-core shielded-pair wires for signal and encoder (PG)
feedback lines.
The maximum length is 3m (118.11 in) for reference input lines and is 20m (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 servo amplifier.
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 servo amplifier has a capacitor in the power supply, a high charging current flows
for 0.2s 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.
