KDA 2.1-150-3-DQD-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-DQD-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat offers high-stiffness spindle control optimized for demanding CNC applications. It delivers a Rated Current of 150 A along with a DC Bus Voltage of 300 V, providing continuous power across a broad speed range. Designed as part of Product KDA, Design 1, and Series 2, the drive balances torque density and thermal management in a compact package. With advanced positioning features and regenerative capabilities, it meets the precision needs of modern machining centers.

The drive’s thermal design includes a Forced Cooled by Heatsink Blower system powered by a dedicated 220 VAC AC Supply Source for Heatsink Blower, ensuring stable operation under heavy load. High-resolution feedback is achieved via an Aux. Encoder Input for 1V Sinusoidal Enc., while the Aux. Interface accepts a Position Command Value Digital 16-Bit Parallel signal for precise control. Speed is commanded through a Digital 16-Bit Parallel interface, allowing seamless integration with standard CNC controllers. The robust DC link and efficient cooling minimize temperature rise, extending service life and reducing maintenance intervals.

The KDA 2.1-150-3-DQD-W1 spindle drive combines robust electrical specifications with advanced digital command capabilities to meet the demands of high-speed machining. Its tailored cooling, high-current capacity, and versatile encoder interfaces make it ideal for precision lathes, milling centers, and grinding machines requiring stable torque and dynamic response. Integration into existing controls is straightforward, reducing commissioning time and maintenance overhead.
