G.9 EMC
Compliance
with
EN61800-3
Use in a Domestic Environment
WARNING
The products covered in this manual are of the restricted sales distribution
class according to IEC 61800-3. In a domestic environment this product
may cause radio interference in which case the user may be required to
take adequate measures.
CAUTION
Because applications differ, it is impossible for the drive manufacturer to
guarantee machine EMC compliance. In some applications, it may be
necessary for the machine builder to incorporate more EMC mitigation
techniques than Danaher Motion had to use in the EMC test setups.
General Suggestions to Improve Machine EMC Performance
Use Danaher Motion cables – Danaher Motion cables have been designed with EMC
considerations in mind. Because subtle differences in cable construction can cause dramatic
changes in EMC performance use of Danaher Motion's motor power and feedback cables is
recommended.
When joining or splicing sections of cable, be sure to maintain the integrity of the cable
shield along the entire length of the finished cable.
Separate cables according to type - AC Mains input, motor power and signal cables should
be separated from each other by at least 100 mm (4 in) to avoid cross coupling between them.
If cables of different types have to cross, they should do so at a 90° angle.
Route wiring close to machine frame - It is a good practice to run wires along the machine
frame (local ground) whenever practical, this couples some high frequency noise/signals that
could otherwise be troublesome directly to the local ground.
Remove paint from all drive, filter, and cable clamp mounting locations.
Add clamp-on ferrites to cables – Adding clamp-on ferrites to noisy cables can reduce
emissions by absorbing RF energy before it is radiated.
Use the appropriate line filter – A line filter is required for CE applications, more information
on line filter selection can be found in D.10
Add a balun to the motor power cable – adding a balun in series with the U, V and W
phases of the motor power cable can attenuate both conducted and radiated emissions.
Ensure that cables shields have a good RF ground – more information on this can be found
in D.10.
