KDA 3.2-150-3-AY0-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-AY0-U1 from the KDA Spindle Drives series is a high-performance main spindle drive engineered for precision machining applications. This Product KDA design 2 unit delivers a Rated Current of 150 A on a DC Bus Voltage of 300 V platform and accepts a Speed Command Value of Analog +/- 10V for fine-tuned speed regulation. Its high stiffness and advanced positioning features ensure consistent accuracy across an extensive speed range under continuous power output. The compact, modular form factor streamlines cabinet integration and conserves valuable panel space.

Cooling and thermal stability are assured by a Forced Cooled by Heatsink Blower system fed from a dedicated AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal junction temperatures even under sustained high-load conditions. Feedback versatility is provided through an Aux. Encoder Input with Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A), enabling precise, multi-source position and speed monitoring. The drive’s architecture omits an Aux. Interface, relying instead on robust analog command and encoder channels for streamlined communication. Built on the proven Series 3 platform, its rugged mechanical construction minimizes vibration and enhances long-term operational reliability.

Designed for demanding manufacturing environments, the KDA 3.2-150-3-AY0-U1 offers a resilient Design 2 enclosure rated for continuous duty. Its combination of 150 A rated current, 300 V DC bus voltage, and analog control flexibility makes it particularly well suited for high-precision milling, drilling, and grinding spindles. Maintenance-friendly features, including modular heatsink blower assemblies, reduce downtime and simplify service interventions.
