01
Key Information
Siemens 6SL3121-1TE23-0AA3 is a SINAMICS S120 Single Motor Module for one motor axis. It accepts the 600 V DC input class and supplies a 400 V three-phase motor output with a 30 A rated current. The module uses the booksize construction, external air cooling, optimized pulse patterns and extended Safety Integrated functions, and Siemens lists the AA3 hardware generation as a cancelled product.

Functions
Core Functions
- Feeds one controlled motor axis from the common SINAMICS DC link.
- Provides a 30 A rated three-phase output stage.
- Uses external air cooling for cabinet thermal management.
- Integrates into the SINAMICS S120 drive topology through DRIVE-CLiQ.
- Supports optimized pulse patterns for the documented power-module generation.
- Works with extended Safety Integrated functions when engineered in the complete drive project.

Installation
- Confirm the complete TE23 order number and 30 A power class before installation.
- Maintain the external-air-cooling path and cabinet cutout defined for this booksize module.
- Reproduce DC-link, motor, protective-earth and DRIVE-CLiQ connections from the approved drawings.
- Restore the motor, encoder, control and safety parameters from the validated drive project.
- Perform insulation, phase-sequence, motor-direction and safety-function checks before enabling the axis.
05
Lifecycle
- Siemens lists 6SL3121-1TE23-0AA3 as cancelled.
- No successor is stated on the exact official product record used for this page.
- Do not infer compatibility from the AA3 suffix alone; the TE23 current class and mechanical design remain decisive.
- Retain the complete drive-project archive and installed-module nameplate data for service work.
- Any modernization should be engineered at system level, including power, cooling, firmware and safety dependencies.
