5.3 Factory settings (defaults) of customer interface on SINAMICS G150 with TM31
The following factory settings are provided to simplify configuring of the optional customer interface on the TM31
(option G60) and commissioning of the drive. Furthermore, the interfaces can be freely assigned at any time.

Note:
If the cables connected to the analog inputs and outputs of the TM31 Terminal Module are more than about 3 to 4 m
in length, isolating amplifiers must be used to ensure reliably EMC-compliant operation. Isolating amplifiers
electrically decouple the signal source and the signal sink, thereby ensuring that any differences in reference
potential between the electronic circuitry of the unit and the higher-level control system do not cause equalizing
currents to flow across the analog signal cables. By this method, it is possible to minimize interference coupling into
the analog signal transmission system and to obtain interference-resistant analog transmission links even in systems
with long cables. For further information about EMC-compliant cabling, please refer to chapter "EMC Installation
Guideline".
