Operating from a 600 VDC supply and providing dual 400 VAC outputs, it delivers 2 × 9 A continuous current, making it suitable for coordinated multi-axis systems and dynamic servo applications. Its Booksize construction supports dense cabinet layouts while maintaining strong thermal performance through internal air cooling. With optimized pulse sampling and high switching frequency, the module achieves smooth torque control and accurate motor regulation across servo, vector, and V/f modes. The integrated safety functions—meeting SIL2 and PL d—ensure compliance with stringent safety standards. The included DRIVE-CLiQ interface enables seamless communication with SINAMICS components, supporting fast commissioning and synchronized system operation. Key Features Dual-Channel Motor Control: manages two independent 9 A motor axes from a single module, optimizing cabinet space and reducing hardware costs. High DC Link Performance: supports a 510–720 VDC link with a 22 A DC-link current, delivering stable energy supply for dynamic load changes. Advanced Control Algorithms: optimized pulse sampling ensures precise torque generation, fast response, and smooth motor operation across servo and vector modes. Integrated Safety Functions: includes SIL2 / PL d / Category 3 protection, enabling safe torque-off (STO) and compliance with industrial safety regulations. Efficient Thermal Management: internal air cooling with only 0.009 m³/s airflow requirement maintains performance even under sustained load conditions. Robust Electrical Design: supports long shielded and unshielded motor cable lengths, high busbar ratings, and reliable operation in industrial environments. DRIVE-CLiQ Connectivity: built-in communication interface ensures fast module detection, synchronized multi-axis operation, and simplified commissioning. Compact Booksize Format: allows high-density mounting and easy integration into SINAMICS S120 drive lineups without increasing cabinet footprint. The 6SL3120-2TE21-0AD0 delivers the reliability and precision required for multi-axis motion systems, high-performance servo control, and integrated safety in demanding industrial automation platforms.
