Component Description
Smart / Active / Basic
Line Module
Line Modules provide the central power supply to the DC link.
Single / Double Motor Module Motor Modules draw their power from the DC link to supply the connec‐
ted motors.
HF Motor Module Operates as inverter and provides the energy for the
connected motor - High Frequency Drive.
S120 Combi Compact and robust multi-axis Power Module for the machine tool.
Power Modules Power Modules provide the energy for the connected motor.
SINAMICS S120, system components, chassis format
Smart / Active / Basic Line
Module
Line Modules provide the central power supply to the DC link.
Motor Module Motor Modules draw their power from the DC link to supply the connec‐
ted motors.
SINAMICS S120, additional system components
SMC10 / 20 / 30 / 40 Cabinet-mounted Sensor Modules are used when a motor with a DRIVE-
CLiQ interface is not available and when external encoders are required
in addition to the motor encoder.
SME20 / 25
SME120 / 125
Measuring systems outside the control cabinet can be connected directly
to the Sensor Module External.
DMC20/DME20 DRIVE-CLiQ Hub Modules are used to implement star-shaped distribution
of a DRIVE‑CLiQ line.
TM15-2/TM31 The number of available digital inputs and outputs within a drive system
can be expanded using a Terminal Module.
TM41 The number of available digital inputs and outputs within a drive system
can be expanded using a Terminal Module; an incremental encoder can
also be emulated.
TM120 The TM120 Terminal Module is used for temperature evaluation with
protective separation. It can be used for 1FN, 1FW6 and third-party mo‐
tors.
CUA31 Adapter to connect a Power Module to the NCU.
VSM10 The VSM10 Voltage Sensing Module is capable of measuring the line
voltage waveform precisely and helps Line Modules to continue func‐
tioning properly under di󹪟cult supply conditions, for example, in the
case of extreme voltage 󹪞uctuations or brief supply interruptions.
HLA Controls (open-loop and closed-loop) electrohydraulic control valves in
hydraulic linear axes in conjunction with SINUMERIK ONE
S120M This is the distributed version of the modular SINAMICS S120 drive sys‐
tem.
