Description

The 6SL3120-2TE21-0AA3 is a SINAMICS S120 double motor module featuring a booksize construction format designed to operate with a 600 V DC input (510-720 V DC supply voltage range) and deliver a 400 V 3-phase AC output with dual 9 A nominal output currents. Manufactured by Siemens, this module is engineered to provide precise, synchronized multi-axis motor control in demanding industrial automation architectures.

The 6SL3120-2TE21-0AA3 utilizes internal air cooling, optimized pulse patterns, and support for extended Safety Integrated functions to ensure high dynamic performance and compliance with advanced plant safety standards. Each unit includes an integrated DRIVE-CLiQ cable for high-speed data communication and system integration. The module measures 27.90 x 5.10 x 45.70 cm and weighs 5.40 kg. As a phase-out lifecycle product with a designated predecessor (6SL3120-2TE21-0AA0) and successor (6SL3120-2TE21-0AA4), it supports legacy maintenance, direct replacement, and operational continuity in established S120 multi-axis drive systems.

Features

  • SINAMICS S120 double motor module in a space-saving booksize construction format
  • Dual-axis output providing 9 A nominal output current per channel
  • DC input voltage operating range of 510-720 V DC (600 V DC nominal)
  • Internal air cooling combined with optimized pulse patterns for high thermal and operational efficiency
  • Extended Safety Integrated functions and included DRIVE-CLiQ cable for seamless system communication

Applications

  • Multi-axis machine tools and machining centers
  • High-performance packaging and handling machinery
