KDA 2.1-050-3-DYI-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-DYI-W1 from the KDA Spindle Drives series combines precision and power in a single package. This Product Model KDA Series 2 Design 1 delivers a Rated Current of 50 A and operates off a DC Bus Voltage of 300 V to support high-performance spindle applications. It features a Cooling Method Forced air via heatsink blower with a dedicated Heatsink Blower Supply 220 VAC to maintain optimal thermal stability under continuous load. Motion feedback is achieved through a Encoder Input Type synchronous & auxiliary inputs and an Encoder Output Interface incremental encoder, while speed commands are handled via a Speed Command Input digital 16-bit parallel interface.

Engineered for demanding machining and milling tasks, the KDA 2.1-050-3-DYI-W1 offers high stiffness characteristics and fine positioning capabilities across an extensive speed range with continuous power output. The integrated forced-air cooling system ensures consistent heat dissipation even at peak currents, extending service life and reducing downtime. With robust electrical protection and low electromagnetic interference, this spindle drive maintains signal integrity and torque stability during rapid acceleration and deceleration phases. Its rugged construction and precise control algorithms optimize dynamic performance, making it ideal for high-speed spindles in tool and die applications.

Installation and commissioning are streamlined thanks to standardized mechanical interfaces and digital parameterization, enabling fast integration into existing control systems. The result is a reliable, high-bandwidth spindle drive solution that delivers repeatable accuracy and long-term operational consistency in the most demanding industrial environments.
