Sensor Module Sme12X - Siemens Simotics T-1FW6 Configuration Manual

NOTICE
Damaged main insulation
In systems where direct drives are used on controlled infeeds, electrical oscillations can
occur with respect to ground potential. These oscillations are, among other things,
influenced by:
•
•
•
•
•
•
•
•
The oscillations lead to increased voltage loads and may damage the main insulation!
•
Note
The corresponding Active Interface Module or the appropriate HFD line reactor must be used
to operate the Active Line Module controlled infeed unit.

Sensor Module SME12x

Sensor Module External SME12x is a module to evaluate:
• Incremental encoders with sin/cos 1 V
• Absolute encoders with EnDat interface (SME125)
• Temperature sensors
The temperature sensors in the motor do not have safe electrical separation in order to
achieve better thermal contact to the motor winding.
The SME12x evaluates the temperature sensors with safe electrical separation.
Information about the SME12x is provided in the "SINAMICS S120 Control Units and
Additional System Components" Equipment Manual.

To dampen the oscillations we recommend the use of the associated Active Interface
Module or an HFD reactor with damping resistor. For specific details, refer to the
documentation of the drive system being used or contact your local Siemens office.
