KDA 2.1-050-3-A0S-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-A0S-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers robust spindle performance with a Rated Current of 50 A and a DC Bus Voltage of 300 V to support high-speed machining tasks and deliver stable torque across variable speeds. It accepts an AC Supply Source for Heatsink Blower of 115 VAC and operates with a Speed Command Value of Analog +/- 10V, enabling fine speed adjustments even under fluctuating load conditions. Forced cooling is provided via a dedicated Heatsink Blower unit with a high-efficiency impeller design, guaranteeing thermal stability under continuous and variable loads. Connectivity is simplified through a Serial Interface RS 232 C auxiliary interface for real-time diagnostics, parameter tuning, and firmware updates, facilitating seamless integration into existing control architectures.

The KDA drive features a compact Design 1 mechanical configuration and is identified as Product KDA, Series 2, maintaining consistent footprint compatibility across multiple machine tool platforms. Although the unit ships Without Aux. Encoder Input, its high-performance control loops and advanced interpolation algorithms deliver precise positioning based solely on spindle feedback. With continuous power handling and rapid dynamic response, the system excels in demanding CNC milling, grinding, and turning operations, providing an extensive speed range and high torque stiffness for complex contouring tasks. The forced-cooling mechanism ensures optimal component longevity and maintains stable operation even during prolonged high-load cycles and rapid start-stop sequences.

Engineered for integration into automated production lines and precision machining centers, the KDA 2.1-050-3-A0S-U1 spindle drive blends continuous output with low-speed rigidity and high-speed agility. The synergy of Bosch Rexroth Indramat engineering, robust construction, and stringent quality protocols ensures reliable, high-precision performance with minimal maintenance requirements in the most challenging industrial environments.
