l
Cable length:
Procedure
1. Total cable length at 125 kbps:
2. Segment cable length for 28 nodes and a cable cross−section
2
of 0.5 mm :
3. Comparison: The value under item 2 is smaller than the required cable length of 1500 m.
Conclusion
l
It is not possible to use a cable length of 1500 m without applying a repeater.
l
After 360 m (item 2.), a repeater must be installed.
Result
l
The Lenze repeater, type 2176 (cable reduction: 30 m), is used
l
Calculation of the max. cable length for the
– first segment: 360 m
– second and every further segment: 360 m (according to Tab. 1) minus 30 m (cable reduction if
a repeater is used)
à Maximum possible cable length with four repeaters: 1680 m.
à Thus it is possible to use the required cable length.

Note!
The use of a further repeater is recommended as
