KDA 2.1-150-3-DPS-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-DPS-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust high-stiffness performance with a rated current of 150 A and a DC Bus Voltage of 300 V. This Product KDA variant is built to Design 1 standards and leverages a Digital 16-Bit Parallel Speed Command Value to achieve precise positioning and speed regulation over an extensive operating range. The spindle drive is forced cooled by heatsink blower and features an AC Supply Source for Heatsink Blower of 220 VAC to ensure consistent thermal management under continuous heavy loads. Its compact footprint and advanced topology make it ideal for integration into high-precision milling, grinding, and turning centers.

Reliability and connectivity are hallmarks of this drive. The Aux. Encoder Input is optimized "with for Spindle or Second Motor Feedback," facilitating dual-loop control architectures. Communication is supported via the Aux. Interface Serial Interface RS 232 C, enabling seamless parameterization, diagnostics, and status monitoring. Forced cooling by the heatsink blower maintains optimal junction temperatures, while the rugged construction withstands the demanding conditions of industrial machining. The drive’s ability to maintain constant torque across its speed range underscores its suitability for high-dynamic applications.

Engineered for straightforward system integration, the KDA 2.1-150-3-DPS-W1 pairs with a variety of motor options and machine tool controllers. Its high reliability and precise digital command interface minimize commissioning time and reduce setup complexity. With its blend of high stiffness, accurate positioning features, and proven cooling architecture, this spindle drive is an excellent solution for modern CNC equipment where performance and uptime are paramount.
