KDA 2.1-150-3-A0S-U1

KDA 2.1-150-3-A0S-U1, Bosch Rexroth Indramat, KDA Spindle Drives offers a robust solution for high-performance spindle applications. Built on the proven KDA platform, it delivers precise positioning and stiffness across a wide speed range, tailored for demanding CNC and milling operations. The drive package integrates seamlessly into machine control architectures, providing reliability and predictable dynamics. Its compact yet rugged design ensures minimal footprint without compromising on thermal management or serviceability.

The drive features a DC Bus Voltage of 300 V coupled with a continuous Rated Current of 150 A, ensuring consistent torque delivery under heavy loads. Command signals are accepted via a Speed Command Value interface of Analog +/- 10V, while the built-in Cooling scheme is a Forced Cooled by Heatsink Blower system powered by an AC Supply Source for Heatsink Blower of 115 VAC. Diagnostics and parameterization are handled through an Aux. Interface using Serial Interface RS 232 C, and the unit is supplied Without any Aux. Encoder Input to simplify integration where separate feedback devices are used. The drive construction adheres to Design code 1 within the product line, and aligns precisely with the KDA Product family, Series 2, ensuring compatibility with existing modules.

Engineers will appreciate the drive’s predictable thermal behavior and easy access for routine maintenance facilitated by front-mounted heat exchanger fans. Integration into CNC controls is streamlined by standard RS-232 connectivity and analog command channels, reducing commissioning time. With its combination of stiffness, power density, and tried-and-tested Bosch Rexroth Indramat reliability, the KDA 2.1-150-3-A0S-U1 excels in high-speed spindle tasks across milling centers, lathes, and multi-axis machining platforms.
