Connection of motors with preassembled cables
Beckhoff offers preassembled motor and feedback cables for safe, faster and flawless installation of the
motors. Beckhoff cables have been tested with regard to the materials, shielding and connectors used. They
ensure proper functioning and compliance with statutory regulations such as EMC, UL etc. The use of other
cables may lead to unexpected interference and invalidate the warranty.
• Carry out the wiring in accordance with the valid standards and regulations.
• Only use our preassembled shielded cables for the power and feedback connections. Incorrectly
installed shielding inevitably leads to EMC interference.
• Cables that move during the operation of the linear servomotor are always to be regarded as wearing
parts. It is advisable to install these with the help of a plug connector between the moved cable and the
motor cable of the coil unit such that simple replacement is ensured. The minimum bending radius of
the respective cable is to be taken from the corresponding data sheets.
• Detailed specifications of the cables can be found on our homepage under
