SIEMENS 6SL3210-1PE31-5AL0 Active Line Power Module – SINAMICS S120 Series
Imagine a high-speed production line grinding to a halt — servo axes losing synchronization, drives tripping on undervoltage, and the entire machine control architecture collapsing because the DC bus can no longer sustain regulated power. In modern multi-axis drive systems, the Power Module is not a peripheral component; it is the energy backbone. Without a properly rated, fully functional Active Line Module feeding the DC link, every downstream Motor Module and servo axis is rendered inoperable. Unplanned downtime in automotive stamping, packaging, or paper-making environments can cost tens of thousands of dollars per hour. The SIEMENS 6SL3210-1PE31-5AL0 exists precisely to prevent that scenario.
The 6SL3210-1PE31-5AL0 is a booksize-format Active Line Module within the SINAMICS S120 drive family — Siemens’ flagship multi-axis servo and vector drive platform trusted across global OEM machine builders and end-user plants alike. Within the S120 booksize portfolio, this module occupies the mid-to-high power range, delivering regulated DC bus voltage with active front-end (AFE) technology that enables four-quadrant operation, sinusoidal mains current, and regenerative energy feedback to the grid. It is engineered for demanding continuous-duty cycles in industries where drive reliability is non-negotiable.

- DRIVE-CLiQ Integration: Plug-and-play digital communication with S120 Motor Modules and Control Units — enables automatic component recognition, parameter upload, and simplified commissioning via STARTER or TIA Portal.
- Booksize Form Factor: Compact, modular design allows tight mechanical integration with S120 Motor Modules on a shared DC bus rail, minimizing cabinet footprint.
- Robust DC Bus Regulation: Maintains stable DC link voltage under dynamic load transients, protecting downstream Motor Modules and connected servo axes.
- Integrated Diagnostics: Onboard LED status indicators and DRIVE-CLiQ fault reporting enable rapid fault isolation without additional instrumentation.
- Long Service Life: Designed for continuous industrial duty with Siemens-grade component selection and thermal management.
Industry & Equipment Applications
- Machine Tool & CNC: Multi-axis machining centers, turning centers, and grinding machines requiring synchronized servo power.
- Packaging Machinery: High-speed form-fill-seal, cartoning, and palletizing lines with frequent start-stop cycles.

Frequently Asked Questions
Q: Is the 6SL3210-1PE31-5AL0 an Active Line Module or a Basic Line Module?
A: It is an Active Line Module (ALM). It uses IGBT-based active front-end technology to provide sinusoidal mains current, power factor correction, and regenerative energy feedback — distinguishing it from Basic Line Modules which use diode rectifiers.
Q: Can this module operate as a standalone drive, or does it require a Control Unit?
A: The 6SL3210-1PE31-5AL0 requires a SINAMICS S120 Control Unit (e.g., CU320-2 DP/PN) for operation. It is not a standalone drive — it functions as the power supply stage within a multi-axis S120 drive system.
Q: What is the difference between the 6SL3210-1PE31-5AL0 and similar S120 Active Line Modules?
A: The part number encodes the power rating and variant. The “1PE31-5A” segment identifies the specific power class within the S120 booksize ALM range. Contact our team for a comparison table if you are evaluating multiple power ratings for your application.
Q: Do you supply new original units or refurbished stock?
A: Both. Please specify your preference and budget in your RFQ. All refurbished units are tested and documented. New original units come with manufacturer packaging where available.
