4.1.3.1 Scanning Head Cable
(Connection cable from scanning head to D-Sub connector)
• Please mount the scanning head preferably on the rigid part and the scale tape on the
mobile part of the machine� If this is not possible, provide a strain relief for the cable
near the scanning head�
• The encoder cables and connecting cables must be laid away from sources of
interference (e.g. mains cables, fuses, motors, magnetic valves or power supplies).
Normally a distance of ≥100 mm will be sufficient.
• Install the cable in a way that it cannot be damaged by the moving carriage� Please pay
attention to the permissible bending radius (see also point 4.2 - “Mechanical data”)!
4.1.3.2 Extension Cable (Connection Cable from D-Sub Connector to Controller)
• Use preferably original extension cables made by NUMERIK JENA� This guarantees
an optimum compatibility with the encoders and ensures a maximum protection against
electromagnetic interferences�
• Please consult the technical support of NUMERIK JENA before using selfmanufactured
extension cables�
• Do not install any other signal lines in the encoder cable!
