KDA 3.1-150-3-DP0-W1

KDA 3.1-150-3-DP0-W1, Bosch Rexroth Indramat, KDA Spindle Drives series defines a new standard in spindle control, combining high stiffness and precision positioning with an extensive speed range. This main spindle drive delivers continuous power optimized for demanding machining and tooling applications. It integrates advanced digital control and robust protection features to maintain peak performance under varying loads. Engineered for seamless integration into CNC systems, it simplifies spindle management while enhancing overall machine dynamics.

The drive accepts a DC Bus Voltage of 300 V and provides a Rated Current of 150 A, ensuring ample torque and speed for high-inertia spindles. Thermal stability is maintained through Forced Cooled by Heatsink Blower design, powered by an AC Supply Source for Heatsink Blower of 220 VAC, which dissipates heat efficiently even under continuous heavy loads. Command input is handled via a Speed Command Value interface with Digital 16-Bit Parallel resolution, while feedback is supported by an Aux. Encoder Input configured With for Spindle or Second Motor Feedback. The unit omits auxiliary communication modules by design (Aux. Interface: Without), streamlining the control cabinet layout. Classified as Design level 1 within the Product family and carrying the Series designation 3, it aligns with industry-standard modular architectures.

Installation and commissioning are expedited through standardized mounting and single-cable encoder connections, reducing wiring complexity and setup time. Reliability is reinforced by rugged power stages and protective interlocks that guard against overcurrent and thermal overload. As part of the Bosch Rexroth Indramat ecosystem, the KDA 3.1-150-3-DP0-W1 drive delivers consistent spindle control, maximizing uptime in precision machining, milling, and drilling operations where accuracy and repeatability are paramount.
