KDA 3.1-150-3-DP0-U1

KDA 3.1-150-3-DP0-U1, Bosch Rexroth Indramat, KDA Spindle Drives combine high dynamic response and precision control in a compact power module. The KDA Series main spindle drive delivers consistent performance across an extensive speed range, making it ideal for demanding machining and milling operations. Built on a robust design, it offers smooth torque generation and rapid acceleration for high-stiffness spindle applications. This drive’s architecture emphasizes modularity and serviceability, reducing downtime during maintenance and upgrades.

In technical operation, the KDA 3.1-150-3-DP0-U1 supports a Rated Current of 150 A and a DC Bus Voltage of 300 V to sustain continuous power output under heavy loads. Its cooling system employs Forced Cooled by Heatsink Blower technology powered by a dedicated AC Supply Source for Heatsink Blower of 115 VAC, ensuring thermal stability even during extended cycles. The drive accepts a Digital 16-Bit Parallel Speed Command Value interface for precise speed regulation and rapid response to control inputs. Feedback integration is facilitated via an Aux. Encoder Input channel optimized for spindle or secondary motor signals, while the Aux. Interface Without additional modules streamlines wiring complexity. Designed as a compact Design 1 enclosure within the KDA Series 3 family, the product package offers ease of mounting and optimal heat dissipation.

Engineers benefit from the KDA 3.1-150-3-DP0-U1’s plug-and-play compatibility with Rexroth Indramat control systems, simplifying integration into existing CNC platforms. The forced-air heatsink blower and robust electrical architecture deliver high reliability in continuous-duty environments. Ideal for precision machining centers and high-speed milling spindles, this drive ensures repeatable accuracy and minimal thermal drift even under the most rigorous production schedules.
