KDA 3.1-050-3-DQI-U1

The Bosch Rexroth Indramat KDA 3.1-050-3-DQI-U1 is a precision KDA Spindle Drives series main spindle drive engineered for high-stiffness positioning and continuous power delivery. This drive features a Rated Current of 50 A and a DC Bus Voltage of 300 V to support demanding spindle applications. Designed as part of the reliable KDA Series, it enables seamless integration into machining centers, ensuring stable torque output and precise speed regulation for high-performance manufacturing processes.

In-depth technical specifications highlight the drive’s robust design and advanced functionality. The heatsink blower is powered by an AC Supply Source for Heatsink Blower of 115 VAC, enabling forced cooling that maintains optimal operating temperatures under heavy loads. It incorporates an Aux. Encoder Input for 1 V sinusoidal encoders and an Aux. Interface with an incremental encoder output, ensuring accurate feedback and closed-loop control. The speed command is processed via a Digital 16-Bit Parallel interface, delivering high-resolution velocity setpoints and rapid response times, which are critical for precision machining cycles.

Additional features underscore compatibility and efficiency in industrial environments. The forced cooling by heatsink blower enhances durability by preventing thermal overload, while the incremental encoder output supports a wide range of servo and spindle motor feedback devices. With a modular Design that adheres to established Bosch Rexroth standards, the drive offers straightforward maintenance and system scalability. Implementing this spindle drive in CNC machining, milling, or grinding applications results in improved cycle times, consistent surface finishes, and reduced downtime, delivering measurable productivity gains across diverse manufacturing operations.
