8.3.2 TM120 Terminal Module
The TM120 Terminal Module is a module for evaluating temperature signals.
The temperature sensors in the motor do not have safe electrical separation in order to
achieve better thermal contact to the motor winding.
Terminal Module TM120 evaluates the temperature sensors with safe electrical
separation.
Information about the TM120 is provided in the Equipment Manual "SINAMICS S120
Control Units and Additional System Components".
8.3.3 SMC20 Sensor Module
The Sensor Module Cabinet-Mounted SMC20 is a module to evaluate:
• Incremental encoders with sin/cos 1 V
PP
interface
• Absolute encoders with EnDat interface
Information about the SMC20 is provided in the "SINAMICS S120 Control Units and
Additional System Components" Equipment Manual.
8.3.4 SMC40 Sensor Module
The Sensor Module Cabinet-Mounted SMC40 is a module that converts encoder signals
from absolute encoders with an EnDat 2.2 interface to DRIVE-CLiQ and transmits them
to the Control Unit.
Information about the SMC40 is provided in the Equipment Manual "SINAMICS S120
Control Units and Additional System Components".
Alternatively, you can use the external interface box EIB 2391 S or EIB 3392 S
(Heidenhain). Both boxes are suitable for connection of absolute encoders with an
EnDat 2.2 interface.
