•
Refer to Sections 1 and 4 of this manual for external fusing information.
•
Motor cable shield must be connected to protective earth.
•
During periods of extreme regeneration or excessively high input voltage the temperature of the
regen resistor may exceed 70 °C.
•
When using an external regen resistor, if regen cabling is accessible during normal machine
operation, regen resistor cable should be rated at 450 VDC and shielded with shield connected to
PE.
•
Consult the factory before using this product on a circuit protected by a residual-current-operated
protective device (RCD).
•
All covers shall be closed during operation.
•
The S200 drives should be used within their specified ratings.

OMPLIANCE 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 Kollmorgen 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 B.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.
