KDA 2.1-050-3-DQ0-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-DQ0-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision and power with a Rated Current of 50 A and a DC Bus Voltage of 300 V. Its compact Design 1 housing integrates a robust Product KDA platform certified for demanding spindle applications. Advanced cooling is handled by a Forced Cooled by Heatsink Blower system powered by an AC Supply Source for Heatsink Blower of 115 VAC, ensuring thermal stability under full load. The drive accepts a Digital 16-Bit Parallel Speed Command Value for highly accurate speed control and features a modular Series 2 architecture for flexible system integration.

Engineering excellence is built into every interface: the unit provides an Aux. Encoder Input for 1V Sinusoidal Enc. to support high-resolution feedback, while the stripped-down Aux. Interface Without additional I/O simplifies installation in lean control cabinets. The drive’s forced-cooling heatsink blower maintains optimal junction temperature, preventing thermal drift during extended cycles. High stiffness and positioning accuracy are achieved through real-time digital control loops, enabling rapid acceleration and deceleration without overshoot.

Designed for main spindle operation, the KDA 2.1-050-3-DQ0-U1 excels in machining centers, grinders, and lathes where continuous power and wide speed range are critical. Integration with Rexroth motion controllers is seamless thanks to standardized electrical connections and parameter sets, minimizing commissioning time. Robust protection features and proven track record in industrial environments make this spindle drive a reliable choice for high-performance metalworking applications.
