KDA 3.3-100-3-AP0-U1

The Bosch Rexroth Indramat KDA 3.3-100-3-AP0-U1 drive controller is a sophisticated spindle drive from the renowned KDA Spindle Drives series. Designed as a Series 3, Design 3 unit, it delivers a 100 A current rated capacity with a 70 A continuous current rating. This controller operates on a 300 V DC bus voltage and is engineered specifically for high-precision spindle control applications, ensuring high stiffness, extensive speed range, precise positioning features, and continuous power delivery.

At its core, the KDA 3.3-100-3-AP0-U1 features an analog +/-10V speed command value input for seamless integration with existing control systems. Its forced cooling system employs a heatsink blower powered by a AC 50-60 V supply to maintain optimal operating temperatures and protect against thermal overload. The unit supports an auxiliary encoder input, enabling feedback for either spindle or a second motor, which enhances motion control accuracy and dynamic response. With robust internal architecture and advanced control electronics, this drive controller excels in demanding industrial environments.

Additional features include compatibility with standard spindle feedback interfaces and a compact design that simplifies installation and maintenance. The forced cooling blower not only prolongs component life through efficient heat dissipation but also contributes to overall system reliability and uptime. Although it doesn’t include an auxiliary interface beyond the encoder input, the KDA 3.3-100-3-AP0-U1's focused feature set ensures streamlined performance. In industrial applications, this spindle drive controller delivers exceptional efficiency, durability, and precise speed regulation, making it an ideal choice for CNC machinery, high-speed spindles, and other automated processes where consistent, high-quality output is critical.
