(*1): The data for the maximum lengths of the fiber optic cables only apply
if the following preconditions have been met:
•
fiber optic cables IKO 982, IKO985 or IKO 001 approved by Rexroth
are used
•
Connection without separating points. If separating points (couplings)
are used, the maximum length for plastic fiber optic cables is reduced
by approx. 10 meters, by approx. 100 meters for glass fiber optic
cables.
The data rate is automatically set by the firmware.
Fiber Optic Cables
Drive controllers with a SERCOS interface are connected to higher-level
control units by means of fiber optic cables.
The fiber optic cables (cable, connector, or the entire ready-made cables)
have to be ordered separately.
For more detailed information on the subject of "fiber optic cables" please
refer to the Application Manual "LWL - Handling" (Fiber Optic Cable
Handling), (DOK-CONNEC-CABLE*LWL**-AWxx-EN-P,
284755).
The following points are dealt with in the "LWL – Handling" (Fiber Optic
Cable Handling) manual:
• general information on fiber optic cables
• basic planning information for optical transmission systems
• instructions for laying fiber optic cables
• attenuation measurement on ready-made fiber optic cable
• available fiber optic FSMA plug-in connectors and fiber optic cables
• instructions for assembling FSMA connectors
• tools for assembling fiber optic cables
