Cables
General specification
Beckhoff offers pre-assembled motor and feedback cables for faster and flawless installation. Design, dimensioning and installation have significant influence on the function of a servo system. Beckhoff servo cables have been tested with regard to the material used, screening and connection, in order to guarantee proper function and compliance with statutory requirements such as EMC. The use of other may invalidate the warranty.

Fire hazard! If several servo drives are operated at the same time the resulting total current of the configuration must be considered for dimensioning of the cables. The information provides in this section should be regarded as guidance. It is not intended as a substitute for professional design based on the specific application. |
