4.10 EMC Control
The servo pack uses high-speed switching electronic components.
Peripheral devices may receive switching noise.
The servo pack uses microprocessor that may receive switching noise
from peripheral devices.
Follow the EMC specications and measures described in this manual when installing and wiring.The
servo pack conforms to relevant standard under
：
●
EN 61800-3
To prevent the noise the servo pack and peripheral devices from causing a malfunction, Take the following
precautions against noise as required.
■
Position the input reference device and noise lter as close to the drive as possible.
■
Always ensure correctly grounding.
■
Do not bundle or run the main circuit cables together with the I/O signal cables or encoder cables
in the same duct.Keep the main circuit cables separated from these signal cables with a gap of at least
30cm.
■
Use twisted pair and shield cables for singal inputs and outputs.
4.10.1 Noise lter
Installing a noise lter in the appropriate place will minimize the noise as much as possible.

Mandatory requirments to conform to EMC:
1) Remove the paint layer on the contact surface when the drive is mounted on a metal plate.
2) Position the input noise lter as close to the drive as possible
3) Always ensure correctly grounding
4) Use shield cables for main circuit. Shield of cable should be directly grounded to PE connector.
