KDA 2.1-150-3-DQ0-U1

The Bosch Rexroth Indramat KDA 2.1-150-3-DQ0-U1 spindle drive is part of the respected KDA Spindle Drives series, offering a robust solution for precision machining and industrial automation. Designed for high stiffness and precise positioning, this main spindle drive delivers a continuous power range that adapts to challenging operational demands. Key specifications include a Rated Current of 150 A and a DC Bus Voltage of 300 V, enabling consistent torque delivery and stable voltage performance under varying loads. The drive’s extensive speed range makes it ideal for applications requiring both fine positioning and high-speed rotation.

Incorporating advanced technical features, the KDA 2.1-150-3-DQ0-U1 employs a forced cooling system driven by a heatsink blower, powered via an AC Supply Source for Heatsink Blower of 115 VAC to maintain optimal thermal conditions during extended operation. The drive supports a Digital 16-Bit Parallel Speed Command Value, ensuring high-resolution speed control and seamless integration with modern CNC controllers. It also includes an Aux. Encoder Input for 1V Sinusoidal Enc., facilitating precise feedback for closed-loop control systems. The unit is built to Design 1 standards within the Product KDA family, and belongs to Series 2, reflecting its generation and compatibility with existing Indramat drive setups.

Additional configuration options such as the Aux. Interface without extra modules streamline installation in space-constrained panels and reduce potential points of failure. The forced cooling mechanism enhances reliability and extends service intervals by preventing thermal overloads, while the solid-state design ensures minimal maintenance requirements. Engineered for compatibility with a broad range of Bosch Rexroth Indramat controllers and encoders, this spindle drive adheres to stringent industrial demands for durability and precision. By delivering accurate speed regulation and robust current capacity, the KDA 2.1-150-3-DQ0-U1 boosts overall system efficiency and reliability in heavy-duty manufacturing environments.
