The Siemens 6SL3120-1TE28-5AA3 is a compact, booksize drive module designed to deliver efficient and stable motor control for industrial applications. It combines precision with power, making it ideal for operations that demand reliability and consistency.

With a rated output current of 85A and a DC-link current of 102A, this drive ensures powerful performance across varied loads. It can handle pulse frequencies of 4.00 kHz, helping maintain smooth motor operation even under changing conditions.

Whether your setup uses V/f, vector, or servo control, this unit can adapt with a flexible output frequency range. It supports up to 650 Hz for servo control, giving you high-resolution performance for demanding applications.

It operates on a DC link voltage range between 510 to 720V and features a robust internal cooling system to maintain thermal stability. This makes it suitable for continuous operations without the risk of overheating.

Even when installed at altitudes up to 1,000 meters, the 6SL3120-1TE28-5AA3 maintains reliable output. With a cooling air requirement of only 0.044 m³/s, it ensures energy efficiency while keeping internal temperatures balanced.

In terms of build quality, Siemens delivers solid performance. The unit features a durable IP20-rated housing, providing basic protection in enclosed panel installations. The open-type UL classification ensures compatibility across global markets.

For safety-focused applications, this drive is equipped with Siemens' Safety Integrated technology. It adheres to SIL 2 standards and complies with Performance Level d (PL d) under ISO 13849-1, ensuring operator and machine protection.

Mechanical installation is made easy with M8 bolt motor connections and M6 grounding screws. It supports cable cross-sections ranging from 2.5 to 95 mm², which offers flexibility during integration into various systems.

The booksize format not only saves space but also simplifies cabinet layout. Measuring just 200 mm wide, 380 mm high, and 270 mm deep, it can be installed in compact control enclosures without sacrificing performance.

Despite its high output capacity, the drive maintains a low sound pressure level of 60 dB at 1 meter. This feature is especially beneficial in applications where noise levels need to be minimized for operator comfort.

With a typical power loss of just 0.77 kW, the drive is designed for efficiency. This not only reduces the energy footprint but also lowers cooling demands within the panel or enclosure.

The unit is rated for a base load power of 37 kW and a full rated power of 46 kW. For dynamic duty cycles (S6, 40%), it can handle up to 110 A, giving you the flexibility to manage high torque conditions.

Thanks to its compliance with global standards such as CE and cULus, the Siemens 6SL3120-1TE28-5AA3 is suited for international installations. This ensures peace of mind when deploying across multinational operations.

The drive’s DC-link busbars can carry up to 200 A, providing ample current-carrying capacity for complex multi-axis systems. Additionally, the 24V electronics supply supports up to 20 A, offering stable auxiliary power for control tasks.

The internal DC-link capacitance of 1,880 µF plays a crucial role in voltage stabilization. It helps maintain consistent drive performance during load transitions or brief input fluctuations.

This model supports shielded motor cables up to 100 meters and unshielded ones up to 150 meters. That makes it suitable for both compact and extended layouts without sacrificing EMC performance.

Installation is versatile and user-friendly. All terminal access points are easily reachable, and the mechanical layout supports fast wiring. This reduces setup time and simplifies maintenance over the product’s lifespan.

The total weight of the module is only 15 kg, making it relatively lightweight for its power class. This allows for easier panel mounting or replacement during servicing or upgrades.

Its 24V electronics supply operates across a wide input range (DC 24V -15%/+20%), providing stable internal power even under minor voltage dips. This enhances reliability in industrial environments.

Built with Siemens’ signature engineering, the 6SL3120-1TE28-5AA3 is durable and designed for long-term industrial use. The internal air-cooling system keeps the unit functioning optimally in ambient temperatures from 0 to 40°C.

From precision automation tasks to high-demand production lines, this SINAMICS drive offers the reliability and adaptability you need. It’s engineered for performance but designed with simplicity and integration in mind.

Whether upgrading existing control cabinets or designing new systems, the 6SL3120-1TE28-5AA3 is a solid investment in performance and safety. Its combination of robust design, flexible controls, and compliance makes it an industry favorite.
