2.2.5 Profibus module, SK CU1-PBR (and SK 750E)
In addition to data connections, the Profibus customer units are also
equipped with conventional digital inputs and outputs. The
SK CU2-PBR can be used in both the SK 700E and the SK 750E
series.
By means of a relay contact, brake control and even warnings to
another system can be initiated.
Various digital functions can be programmed for the input. The
digital input has a 2.5V switching threshold for the evaluation of the
temperature sensor.
The bus termination resistor (R
ab
) can be switched in. For this, both
switches must be set to 'On'. A transfer rate of up to 1.5Mbit/s can
be used.

Note
The cable shield must be connected to the functional earth
3
(usually the
electrically conducting mounting plate) in order to avoid EMC interference in the
device.
With the two SK 8 shield terminals enclosed with option, the Profibus cables can be
connected to the shield bracket of the frequency inverter.

3 In systems, electrical equipment is usually connected to a functional earth. This serves as a means to dissipate leakage and
interference currents in order to ensure EMC characteristics and must therefore be implemented according to high frequency
technology aspects.
