5.3 Installation of a DC-typical drive system
General notes
ƒ The electromagnetic compatibility of a machine depends on the type of installation
and care taken.Especially consider the following:
– Structure
– Filtering
– Shielding
– Earthing
ƒ For diverging installations, the conformity to the CE EMC Directive requires a check
of the machine or system regarding the EMC limit values. This is valid, for instance,
when:
– Using unshielded cables
– Using collective suppression filters in place of the assigned RFI filters
– Operating without RFI filters
ƒ The compliance of the machine application with the EMC Directive is in the
responsibility of the user.
– If you observe the following measures, you can assume that the machine will
operate without any EMC problems caused by the drive system and that
compliance with the EMC Directive and the EMC law is achieved.
– If devices which do not comply with the CE requirement concerning noise
immunity EN 61000-6-2 are operated close to the axis modules, these devices may
be disturbed electromagnetically by the axis modules.
Structure
ƒ Install the capacitor module between the power supply module and the axis
module(s)..
– For cable lengths > 5 m we recommend to install the capacitor module as close as
possible to the axis module with the highest power.
ƒ Connect power supply modules, capacitor modules, axis modules, RFI filters, and
mains choke to the earthed mounting plate with a large surface:
– Mounting plates with conductive surfaces (zinc-coated or stainless steel) allow
permanent contact.
– Painted plates are not suitable for the installation in accordance with the EMC.
ƒ If you use several mounting plates:
– Connect the mounting plates electrically with a large surface (e.g. with copper
bands).
ƒ Ensure the separation of motor cable and signal or mains cable.
ƒ Do not use the same terminal strip for mains input and motor output.
ƒ Lay the cables as close as possible to the reference potential. Freely suspended
cables act like aerials.
