EMC, earthing, shield connection and potential

The AX5000 corresponds to EMC category "C3" (industrial sector) in terms of conducted interference emissions. If you wish to use components which comply with a higher category you can limit the AX5000 conducted interference emissions with the aid of additional filters to such a degree that this complies with the EMC category "C2" (residential and industrial environment) or "C1" (residential environments). Ensure that there is adequate earthing (large-area low-impedance integration) of all relevant components (incl. control cabinet). The AX5000 incl. periphery, control cabinet, machine bed and motors must be at the same potential, as the AX5000 control quality will suffer under differing potentials and operational malfunction may result. Using the shield connection for potential equalization is not permitted. If you cannot ensure a uniform reference potential, you must install adequately sized equipotential bonding conductors. Smooth operation is only guaranteed by faultless shield connections of the cables. The shields must be applied generously at both ends and must on no account be disconnected. Use Beckhoff pre-assembled motor and feedback lines, as they are optimally matched to the drive system and minimize interference. Ensure that the connectors are properly connected: this applies to the motor connector in particular.
