2.5 Instructions on EMC
The EU Electromagnetic Compatibility Directive (2004/108/EC) applies to equipment that may
cause electromagnetic emissions or whose operation may be affected by such emissions.
The instructions for ensuring EMC must be followed in order to guarantee EMC safety of the
machine.
Applicable special standard:
DIN EN IEC 61800-3: Adjustable speed electrical power drive systems
Part 3: EMC requirements including specific test procedures
Special measures to increase the immunity to interference in plants are listed below:
•
Ground the panel and the frame:
•
via the mounting flange – the D end is not grounded
•
via machine
•
via PE of the motor line connected to the servo amplifier
•
via grounding terminals in the control cabinet
•
Connect the resolver or the HIPERFACE®
•
Connect the motor lines. The toroidal cores or the motor choke must be placed near the
servo amplifier. Shield cables on both ends.
•
Connect holding brake, if available, and connect the shield on both ends of the cable.
•
If you use a motor power cable which includes conductors for brake control, the brake
control conductors must be shielded separately. Ground the shielding braid on both
ends.
