2.3.6 EMC Guide
EMC suggestions:
Immunity
360 degree ground clamps should be used to connect the screen of the cable; avoid
"Pigtail" ground fitting.
Control cable and power cable should be lainoutin independent metal grooves; the earth
conductor in the motor cable must be connected directly to the earth terminal of the drive
and the motor. Shielded motor cable is recommended.
Cable clearance
Don’t place control cable in a zone extending 300mm around the drive and power cables.
2.3.7EMC Filter
Optional RFI filter
Place the RFI filter to the drive as close as possible, and the shorter the cable
between the filter and drive is, the better.
The metal enclosure of the filter must be connected with the drive earth terminal.
Internal EMC filter
The drive leakage current is different when with internal EMC filter and when without.
