ABB 3BHE014135R2011 Redundant channel card

To meet the conducted EMC requirements, an external line filter is necessary. It is your responsibility to choose appropriate filtering for the application. Danaher Motion is willing to assist in this choice. The CE test setup included a 50CE4 line filter manufactured by MTE. CE testing was performed using 50 m motor and resolver cables, the maximum lengths specified, to prove worst case conducted emissions compliance. For CE testing with 50 m cables, a motor cable balun was added to the motor wiring (part number 104-090003-01). The line filter should be mounted as close as possible to the drive. To provide maximum high frequency filtering, remove any paint from between the filter, the drive and the conductive surface ground plane to which they are bonded.

Shielding & Grounding 

To meet radiated EMC requirements, shield and ground the serial, Command I/O, motor and resolver cables at the drive end. To guarantee maximum high frequency radiated noise reduction, the shields should have 360° termination to ground. Clamp the exposed portion of the shields to the front of the drive with the clamp supplied to terminate. The serial and command I/O cables can be terminated to ground through the D-sub connector, if it provides 360° shield termination. It may also be necessary to add ferrites to the Command I/O and serial cables. It is important to remove the paint from any grounding surfaces. To avoid the risk of cross-talk, keep the motor and resolver cables away from sensitive signal cables such as telephone and intercommunication lines.
