Product Description:

The KDA 2.1-100-3-LP0-W1 is a standard drive unit specially designed to be used in Indramat AC servo motors, delivering stable single-axis control in compact size and simplified design. The module delivers a sustained current, which makes it suitable for power-intensive motor drives that require stable delivery of power. The module is approximately 100 mm wide, implying that it could fit snugly into panel installations without occupying a lot of space.

This model is W1-designated, meaning that it lacks fieldbus or communication interface—ideal for installations where advanced networking is not required. It focuses on plain, direct control without additional layers of communication. The unit's protection class is IP10 when properly installed, offering basic protection against invasion and requiring enclosure in a control cabinet to offer a safe working environment. Weighing at approximately 9 kg, the drive is lightweight for its class, allowing for simplicity in use and quick assembly of the cabinet. LP0 being the version indicates the model does not offer regeneration and will therefore be more suitable for applications where braking energy need not be fed back to the system. Being compact in design and featuring fewer external interface options simplifies the complexity of installation and reduces integration issues. No fieldbus interface keeps potential software conflict to a minimum, and ensures stable and predictable drive behavior. The IP10 protection level, while minimal, is typical of parts intended for guarded environments and allows for sufficient ventilation of internal parts. It operates without redundant complication, focusing instead on simple performance and compatibility with standard Indramat systems.

The model is best suited for simple motor control systems requiring stable power, basic protection, and simpler architecture. The KDA 2.1-100-3-LP0-W1 is a small, no-frills drive solution that delivers power, space savings, and simplicity, which translates to a tried-and-tested solution for use in systems with high-performance Indramat AC servo motors where regeneration and communication interfaces are not needed.
