Active Line Module for SINAMICS S120 drives
The Siemens 6SL3130-7TE31-2AA1 is a SINAMICS S120 Active Line Module, listed as a spare part. It takes a 380-480 V three-phase AC input at 50/60 Hz and delivers a regulated 600 V DC bus at 200 A, supporting a power rating of 120 kW. Internal air cooling handles the thermal load, and the module ships with the Control Voltage Adapter and a DRIVE-CLiQ cable — meaning you don't need to order those separately for commissioning. This is the regenerative-capable front end for a multi-axis S120 drive group. The 600 V DC output feeds the DC link common to several Motor Modules; the 200 A rating sets the total current budget for all connected axes. Sizing the line module correctly for the sum of motor currents avoids DC-link sag under load.
The module uses internal air cooling — no external fan or coolant plumbing required, but the enclosure must allow free convection or forced airflow around the heatsink. Mount it with clearance above and below for vertical airflow; stacking other heat-generating gear directly adjacent will reduce the thermal headroom. The included DRIVE-CLiQ cable connects the line module to the S120 Control Unit for communication and feedback. The Control Voltage Adapter supplies the 24 V DC electronics power from the DC bus or an external source — verify the adapter's input range matches your auxiliary supply before wiring.
