6SL3120-1TE23-0AA3 Siemens SINAMICS S120 Single Motor Module

1.Overview of the 6SL3120-1TE23-0AA3 Siemens

The Siemens 6SL3120-1TE23-0AA3 is a booksize single-motor module and a key component of the Siemens SINAMICS S120 multi-axis drive system. It converts 600V DC power from the DC busbar into three-phase AC power for output to the motor, making it ideal for complex motion control with high performance and high dynamic response. This SINAMICS S120 "booksize" single-axis drive module, powered by the DC bus and rated at 30A, is suitable for 400V-class permanent magnet synchronous/asynchronous servo motors with a power range up to 16kW. It is a workhorse motor for high-dynamic applications such as high-end machine tools, robotics, and packaging lines.

High power density: 30A rated, 56A peak (40% duty cycle) in a single, 50mm-wide package, it can be accommodated in a standard S120 booksize slot.
Fully closed-loop plug-and-play: A built-in DRIVE-CLiQ port automatically recognizes encoders (incremental, absolute, and resolver), eliminating the need for manual encoder selection. The default pulse frequency is 4 kHz, and it can be set up to 8 kHz, balancing high torque at low speed with low noise at high speed.
Internal air cooling and spring-loaded terminals, along with IP20 enclosure installation, reduce maintenance time by 50%.
Safety Integrated: Supports STO (Safe Torque Off) up to SIL3/PL e, enabling safe shutdown without the need for external contactors.
