KDA 2.1-150-3-D0I-U1

The KDA 2.1-150-3-D0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives series main spindle drive delivers precise, high-stiffness motion control across a wide speed range. This robust unit supports a continuous Rated Current of 150 A and operates on a DC Bus Voltage of 300 V, providing the torque and dynamic response essential for advanced machining applications. Featuring integrated positioning functions and a broad speed spectrum, the drive ensures smooth acceleration and deceleration, maintaining spindle rigidity under load. The drive’s construction emphasizes mechanical resilience, backed by decades of Rexroth Indramat expertise in spindle technology.

Incorporating a Digital 16-Bit Parallel Speed Command Value interface, the drive accepts high-resolution data for sub-microsecond velocity updates, while the Aux. Interface output provides an Incremental Encoder Output for real-time feedback. Forced cooling is handled by a dedicated heatsink blower rated to AC Supply Source for Heatsink Blower 115 VAC, delivering consistent thermal management even under peak loads. The design specification Design 1 ensures compatibility with existing KDA installations, and the absence of an Aux. Encoder Input simplifies configuration in standard setups. These features combine to deliver a spindle drive that balances power density with user-friendly integration, minimizing cabinet space without sacrificing performance.

Engineers will appreciate the drive’s plug-and-play compatibility with Bosch Rexroth ecosystems and its proven operational reliability in continuous-duty scenarios. The drive’s sturdy cooling system and robust electronics enhance uptime, reducing maintenance intervals and thermal derating risks. Ideal for CNC milling, turning centers, and high-precision grinding machines, the KDA 2.1-150-3-D0I-U1 ensures consistent spindle control for demanding manufacturing environments.
