H2 BusLeitgsLaenge-Leitungslaenge_3

Test sequence Cable length See

1. Total cable length at 125 kbps: 590 m From Tab. 1

2. Segment cable length for 28 nodes and a cable cross-section

of 0.5 mm

360 m From Tab. 2

3. Comparison: The value under item 2 is smaller than the required cable length of 450 m.

Conclusion



It is not possible to use a cable length of 450 m without a repeater.



After 360 m (item 2.), a repeater must be installed.

Result



The Lenze repeater type 2176 is used (cable reduction: 30 m)



Calculation of the maximum cable length:

First segment: 360 m

Second segment: 360 m (according to Tab. 1)

minus

30 m (cable reduction when a repeater is

used)



Maximum possible cable length with repeater: 690 m.



Thus it is possible to use the required cable length.



Note!

The use of another repeater is recommended as

Service interface

Advantage:

Trouble-free connection during running bus operation is

possible.

Calibration interface

Advantage:

calibration/programming unit remains electrically isolated.
