KDA 3.2-050-3-D0S-W1

The Bosch Rexroth Indramat KDA 3.2-050-3-D0S-W1 drive is a high-performance component of the KDA Spindle Drives series, engineered to deliver precise control and robust power delivery in demanding machining applications. With a Rated Current of **50 A** and a DC Bus Voltage of **300 V**, this spindle drive offers a broad speed range and continuous power capability. It features a Digital 16-Bit Parallel Speed Command Value, ensuring accurate and repeatable positioning, and its primary function is to regulate spindle speed and torque in CNC machining centers.

In terms of technical specifications, the KDA 3.2-050-3-D0S-W1 utilizes a forced cooling system via a Heatsink Blower powered by an AC Supply Source for Heatsink Blower of **220 VAC**, maintaining optimal operating temperatures under heavy load. The unit incorporates a Serial Interface RS 232 C as its auxiliary interface, providing reliable data exchange for parameterization and monitoring. Although it is specified as having no Aux. Encoder Input, the drive’s integrated digital command interface ensures seamless speed control for motor feedback loops. The device is classified under Design 2 and identified by Product KDA within the Series 3 family, reflecting its modular construction and compatibility with standard Indramat control systems.

Built for industrial durability, the KDA drive’s forced-cooled heatsink design enhances thermal efficiency and extends service life by preventing overheating during continuous operation. Its standardized serial interface complies with common automation protocols, facilitating quick integration into existing control architectures. The absence of an auxiliary encoder input streamlines installation where self-contained speed feedback is sufficient, reducing wiring complexity. Overall, the KDA 3.2-050-3-D0S-W1 spindle drive delivers reliable precision, efficient thermal management, and robust current capability, making it an ideal choice for high-speed, high-stiffness applications in modern manufacturing environments.
