System Wiring Requirements 3.1.2
Pay attention to the following when wiring the main circuit:

It is recommended to use the twisted-pair wire or multi-core twisted-pair overall shielded wire as the input/output signal
line and encoder cable.

Do not press or damage the cable.

Power cables should be wired separately with signal lines and encoder cables.

Power supply input cables should be wired separately with power output cables.
In order to suppress the electromagnetic interference between the servo drive and surrounding devices, the following
anti-interference measures can be taken as necessary:

Whenever possible, set the input instruction device and anti-interference filter near the servo unit.

Always attach the surge absorber to the coil of the relay, solenoid valve, and solenoid contactor.

Do not put the main circuit cable and the signal cable in the same sleeve, do not bundle them together, and keep a
distance of more than 30 cm between them.

Do not use the same power supply as electric welding machines, electron discharge machines, etc. Even if it is not the
same power supply, when there is a high-frequency generator nearby, connect an anti-interference filter to the input side
of the main circuit power cable and the control power cable.

Perform proper grounding. Refer to the content below for information about grounding.
When connecting the ground wire, pay attention to the following:

In any case, the cross-sectional area of each protective conductor that is not part of the power cable or cable sheath
should not be less than:

2.5 mm
2
, if with mechanical protection;

4 mm
2
, if without mechanical protection. For devices connected with the cable core, measures should be taken to
make the protective conductor in the cable core the last interrupted conductor upon the failure of the stress relief
mechanism.

Single-point grounding is recommended.

When the servo motor and the machine are insulated from each other, ground the servo motor directly.

When interference occurs in the I / O signal cable, connect the shield layer of the I / O signal cable to the connector
housing before grounding.
