In order to be able to control the load current, it is recommended that an external actual
current sensing circuit be used for these applications. Whereby, the entire load current
(including the freewheeling current) is measured via an external shunt. The shunt voltage
must be increased via an external shunt converter and then led to the SINAMICS DCM via
an analog input. See function diagram 6850, column 2.
