Mini USB Cable
Upper Device
(PLCs with RS422 or RS485 ports,
such as Click, P-Series, Do-More, etc.)

Molded Circuit
Breaker
This is used to protect the
power line.
It turns off the circuit
breaker when there is
overcurrent.
Noise Filter
This blocks external noise
from the power line.
Magnetic Contactor
Turn the servo power

RS-422 Communication and I/O
RS-422 Communication Cable
(compatible with RS485 PLCs, such
as Click, Productivity, and Do-More)
NOTE: Do not use APC-VSCN1T(xx)-AD or APC-VPCN1T-AD if using PLC/Drive serial
communication. Communication may be poor due to disconnection in cable shields. Build the
structure of a single connector holding individual lines of RS-422 communication cables and
input/output cables. Make sure to use shielded twisted cables (Twisted Pair Wire) for RS-422
communication cable.
NOTE: PE between the servo motor and the servo and between the servo and the device must
be connected.
