AXIMA® 2000/4000 Multi-Axis Controller Installation Manual
Restoring default parameters set in certain applications may cause unpredictable or hazardous
operation.
Safety of Machinery
Within the European Union all machinery in which this product is used must comply with
Directive 89/392/EEC, Safety of Machinery.
The AXIMA 2000/4000 hardware and PowerTools software are designed and tested to a high
standard, and failures are very unlikely. However the level of integrity offered by an AXIMA
2000/4000 control function – for example stop/start, forward/reverse and maximum speed –
is not sufficient for use in safety-critical applications without additional independent channels
of protection. All applications where malfunction could cause injury or loss of life must be
subject to a risk assessment, and further protection provided where needed.
Electromagnetic Compatibility (EMC)
The AXIMA 2000/4000 controllers are designed to the high standards of EMC. Under
extreme conditions an AXIMA 2000/4000 controller might cause or suffer from disturbances
due to electromagnetic interaction with other equipment. It is the responsibility of the installer
to ensure that the equipment or system into which the drive is incorporated complies with the
relevant EMC legislation in the country of use.
The following instructions provide you with installation guidance designed to help you meet
the requirements of the EMC Directive 89/336/EEC.
Although Control Techniques cannot guarantee your system will meet tested emission or
immunity requirements, adhering to the following guidelines will greatly improve the
electromagnetic compatibility of your system.
• Choose an enclosure made of a conductive material, such as carbon steel, aluminum or
stainless steel.
• Devices mounted to the enclosure mounting plate, which depend on their mounting
surfaces for grounding, must have the paint removed from their mounting surfaces and the
mating area on the mounting plate to ensure a good ground. The AXIMA 2000/4000
controller does not require removal of paint.
• If grounding is required for cable grommets, connectors and/or conduit fittings at
locations where cables are mounted through the enclosure wall, paint must be removed
from the enclosure surface at the contact points.
• AC line filter input and output wires and cables should be shielded, and all shields must
be grounded to the enclosure.
Although final responsibility for EMC compliance rests with the machine builder, we are
including the following installation suggestions. They describe the components that were
used and how they were installed during the EMC compliance testing.
