KDA 3.2-100-3-DQI-W1

The Bosch Rexroth Indramat KDA 3.2-100-3-DQI-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat combines rigorous mechanical design with advanced electrical performance, delivering a rated current of 100 A at a DC Bus Voltage of 300 V. The spindle drive’s cooling is handled by a forced-cooled heatsink blower drawing from a dedicated AC Supply Source for Heatsink Blower of 220 VAC, ensuring stable thermal behavior under continuous load. Precise motion control is achieved through a Digital 16-Bit Parallel Speed Command Value, which allows sub-microsecond adjustments across an extensive speed range. Compact and robust, this drive integrates seamlessly in machining centers, leveraging its high stiffness and positioning features to optimize spindle dynamics.

Featuring an auxiliary encoder input capable of accepting 1 V sinusoidal signals, the drive enhances feedback fidelity for ultra-smooth acceleration and deceleration profiles. An auxiliary interface provides an incremental encoder output for direct integration with CNC controllers and motion systems. The internal design designation 2 underscores a two-quadrant power stage architecture, while the product designation KDA and series identifier 3 align with Bosch Rexroth’s modular platform strategy. These configurations are factory-calibrated to maintain reliable spindle torque under varying cutting forces, supporting continuous power delivery and rapid torque response.

Engineered for industrial spindles, this drive’s heat management and digital command structure deliver exceptional dynamic performance and long-term reliability. With full support for incremental encoder interfacing and a dedicated blower supply, the KDA 3.2-100-3-DQI-W1 is an ideal solution for high-precision milling, drilling, and grinding applications where both power density and positional accuracy are critical.
