KDA 3.3-100-3-D0D-W1

The Bosch Rexroth Indramat KDA 3.3-100-3-D0D-W1 from the KDA Spindle Drives series delivers robust spindle control with a rated current of 100 A and a DC Bus Voltage of 300 V. This Product KDA features a Design 3 chassis engineered for high stiffness and precise positioning under continuous load. Its enforced cooling strategy is powered by an AC Supply Source for Heatsink Blower of 220 VAC, ensuring thermal stability in demanding machining cycles. The drive’s auxiliary interface supports a Position Command Value Digital 16-Bit Parallel protocol for seamless integration with CNC controllers.

Reliability is built into every aspect of the KDA 3.3-100-3-D0D-W1. A Cooling system via forced heatsink blower expels heat consistently, while the absence of an Aux. Encoder Input simplifies configuration and avoids unnecessary faults. Dual safety interlocks in the parallel interface protect against signal loss, and the drive’s modular architecture aligns with Bosch Rexroth Indramat’s maintenance guidelines for rapid serviceability. The compact layout retains full power density without compromising on performance or service access.

Engineers will appreciate the precise Speed Command Value: Digital 16-Bit Parallel feedback channel, which maintains velocity accuracy across the entire speed range. With its dedicated heatsink blower supply, robust power stage, and CNC-ready digital interface, the KDA 3.3-100-3-D0D-W1 embodies industrial-grade spindle control for milling, drilling, and grinding applications where repeatable torque and stiffness are critical.
