KDA 2.1-050-3-APD-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-APD-U1 spindle drive, part of the KDA Spindle Drives series, is manufactured by Bosch Rexroth Indramat and offers robust performance with a rated current of 50 A and a DC bus voltage of 300 V. This Product KDA model features a compact Design 1 footprint optimized for high-stiffness applications while delivering continuous spindle power. Its broad speed range and precise positioning capabilities make it ideal for demanding CNC and milling processes. With native support for advanced feedback and command interfaces, it streamlines integration in modern machine tool architectures.

Reliability is ensured through forced cooled by heatsink blower thermal management, powered by a dedicated AC supply source for heatsink blower at 115 VAC that maintains stable operating temperatures under heavy load. Command input flexibility is provided by an auxiliary interface with 16-bit parallel position command value, while an auxiliary encoder input with support for spindle or second motor feedback guarantees high-resolution motion control. The drive accepts a speed command value of Analog +/- 10V for smooth acceleration profiles and dynamic response. Robust electronics and precision cooling enable sustained operation even in high-duty cycles.

Engineered for precision spindle applications, the KDA 2.1-050-3-APD-U1 delivers consistent torque output and exceptional rigidity, reducing vibration and enhancing surface finish quality. As a member of Series 2, it benefits from standardized mounting and electrical connectors that accelerate setup and maintenance. Whether deployed in tool grinders, high-speed drills, or contouring mills, this spindle drive combines advanced I/O, proven cooling methods, and powerful DC bus capacity to meet the toughest industrial automation demands.
