AKD Installation | 7 Technical description and data
7.12 Cable and Wire Requirements
7.12.1 General
For information on the chemical, mechanical, and electrical characteristics of the cables
please refer to the accessories manual or contact customer support.
To reach the maximum permitted cable length, you must use cable material with the fol-
lowing capacitance (phase to shield) requirements:
Motor cable: less than 150 pF/m
Resolver/Encoder cable: less than 120 pF/m
Motor cables longer than 25 m may require the use of a motor choke.
7.12.2 Cable cross sections and requirements
The table below describes the recommended interface cross sections and cable require-
ments for single-axis systems in accordance with IEC 60204. For multi-axis systems,
observe the specific operating conditions for your system.
