Connecting the field bus
3.7.1
Field bus cable
Note
If installation has not been carried out correctly and if high
baud rates are used, data transmission errors may occur
as a result of signal reflections and attenuations.
Causes of the transmission faults can be:
missing or incorrect terminating resistor
incorrect screening/shield connection
branches
too long or not terminated branch lines
transmission over long distances
unsuitable cables.
Observe the cable specifications. For information on the
cable type refer to the manual for your controller or to CIA
specification DS102.
Note
If the SFC−LAC is fitted onto the moving part of a machine,
the field bus cable on the moving part must be provided
with strain relief. Please observe also the relevant regula
tions in EN60204 part 1.
Use a twisted−pair screened 4−wire cable as the field bus
cable.
If the field bus plug FBS−SUB−9−BU−2x5POL−B is used, a cable
diameter of 5
Ū
10 mm is permitted.
