Installation of the CE typical drive system
The electromagnetic compatibility of a drive system depends on the type and
accuracy of the installation.
Take special care with
− filters
− screening
− grounding
Filters
•
Only use the RFI filters and mains chokes allocated to the controllers (see
chapter 3 "Accessories").
−
RFI filters reduce non-permissible high-frequency interferences to a
permissible value.
−
Mains chokes reduce low-frequency interference which depends primarily
on the motor cables and their length.
For motor cables which are longer than 50 m additional measures are
required.
Screening
•
Screen all cables from and to the controller.
•
Make sure that motor cables are separated from signal and mains cables
when laying the cables.
•
Avoid a common terminal board for mains input and motor output.
•
The cables must be laid as close as possible to the reference potential.
Dangling cables are like antennas.
