Description
6SL3130-7TE31-2AA3 is a Booksize Active Line Module for Siemens SINAMICS S120 drive system. It converts three-phase AC input into regulated DC link voltage and supports regenerative power feedback back to the grid. This 120kW infeed unit works together with S120 power modules to build multi-axis servo drive systems for machine tools, printing presses and high dynamic automation equipment. Drive-CLiQ interface enables fast digital communication between infeed and power modules.

Key Features
- Regulated active infeed with full power regeneration capability, feeds braking energy back to AC mains to reduce heat loss
- Unity power factor in active operation, suppresses harmonic distortion of the power grid
- Booksize compact design for cabinet installation, integrated fan for internal air cooling
- High-speed Drive-CLiQ digital link for reliable synchronization between line module and power modules
- Adjustable DC link voltage; supports Active Mode and Smart Mode operation
- Built-in comprehensive protection: overvoltage, undervoltage, overcurrent, over temperature, short-circuit protection
- Parallel-capable for higher total system power when multiple ALM units are matched
Application Scenarios
- CNC machine tools and machining centers
- Printing, paper and converting machinery
- Gantry and multi-axis handling systems
- Plastics injection and extrusion equipment
- High-performance test stands requiring regenerative braking
Installation & Maintenance Notes
- Mount vertically in control cabinet; maintain sufficient clearance for fan air intake and exhaust
- Use recommended Siemens line reactor and EMC line filter to meet harmonic and emission requirements
- Proper protective earth grounding is mandatory; separate power and signal wiring routing
- Verify Drive-CLiQ cable connections before power-up; avoid hot swapping Drive-CLiQ cables under power
- Regularly inspect cooling fan and air filter for dust accumulation; clean filter during scheduled shutdown
- Do not perform high-voltage megger insulation test on power electronics module
- Backup drive parameters via STARTER software for fast replacement and commissioning
FAQ
Q: What is the difference between Active Line Module (ALM) and Smart Line Module (SLM)? A: ALM can regulate DC voltage and return regenerative energy to grid with unity power factor. SLM is unregulated DC link, lower cost and limited regenerative capability.
Q: Can multiple 6SL3130-7TE31-2AA3 modules be paralleled? A: Yes, matched ALM units can be connected in parallel to increase total infeed power for large multi-axis drive systems, following Siemens parallel wiring guidelines.
