Siemens 6SL3210-1KE23-2UB1 SINAMICS G120C USS compact converter

Siemens identifies 6SL3210-1KE23-2UB1 as a SINAMICS G120C compact converter with no integrated line filter and USS fieldbus. The converter is rated for 3 AC 380-480 V input, 15.0 kW low-overload output, and 11.0 kW high-overload output.

System function and position

Rebuilt from individual evidence

Siemens identifies 6SL3210-1KE23-2UB1 as a SINAMICS G120C compact converter with no integrated line filter and USS fieldbus.

The converter is rated for 3 AC 380-480 V input, 15.0 kW low-overload output, and 11.0 kW high-overload output.

The documented interface provides 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output, and integrated Safe Torque Off.

Unknown: exact motor compatibility, installed Control Unit pairing, commissioning parameters, and current commercial availability require separate evidence.

The documented product function places this unit in the drive power path between the supply, control layer, and motor.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts three-phase line power into controlled drive power for a motor in a G120C system.
System position: Sits in a G120C drive between the three-phase supply and a motor, with USS carrying control data to and from the drive.
Upstream / inputs: Receives three-phase line power and USS control data through its documented converter interfaces.
Downstream / outputs: Delivers controlled three-phase drive power to the motor and exchanges drive data through USS.
Limitations: Unknown: exact motor compatibility, installed Control Unit pairing, commissioning parameters, and current commercial availability require separate evidence.
