The Bosch Rexroth Indramat KDA 2.1-150-3-DY0-W1 from the KDA Spindle Drives series delivers a continuous operating current of 150 A at a three-phase 380-480 V AC supply with a DC bus voltage of 300 V for demanding spindle applications. An integral fan provides forced cooling by heatsink blower to maintain stable operating temperatures under heavy loads and prolong component life. Featuring native SERCOS communication, the drive accepts a Digital 16-bit parallel speed command value for high-resolution speed regulation and precise spindle control. At approximately 18 kg, it combines robust performance with manageable system integration, making it suitable for both new installations and retrofit projects in industrial automation.
The drive supports auxiliary encoder input configurations via synchronous inputs such as AS 35, enabling precise position feedback and advanced motion-profiling capabilities. Its heatsink blower is optimized for a supply frequency range of 50 to 60 Hz, ensuring consistent heat dissipation during continuous operation without derating. Designed for harsh industrial environments, the unit tolerates storage and transit temperatures from -30 to +55 °C and can be installed at altitudes up to 1000 m above sea level without performance loss. The pure AC supply source type simplifies integration with standard industrial power networks, while the plug-and-play interface architecture accelerates commissioning.
As product KDA, series 2, design 1, this spindle drive embodies Bosch Rexroth’s commitment to reliable, high-performance motion control solutions. Its rugged construction, advanced thermal management, and comprehensive electronic interfaces deliver extended service life and minimal downtime. The KDA 2.1-150-3-DY0-W1 is the optimal choice for precision spindle tasks in demanding industrial automation environments where accuracy, durability, and ease of integration are paramount.
