KDA 3.1-050-3-A0S-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-A0S-W1 from the KDA Spindle Drives series combines precision engineering and robust performance in a compact drive package. This main spindle drive delivers a Rated Current of 50 A and operates on a DC Bus Voltage of 300 V, ensuring consistent power delivery across broad machining applications. Its Speed Command Value is provided via Analog ±10 V, offering seamless integration with standard CNC controls. Advanced Forced Cooled by Heatsink Blower thermal management maintains optimal operating temperatures under continuous load.

Built on Design 1 architecture with the core Product KDA platform and classified under Series 3, this drive excels in stiffness and dynamic response. Auxiliary interfaces include a Serial Interface RS 232 C for parameter tuning and monitoring, while the Aux. Encoder Input is omitted to streamline wiring in spindle-centric applications. The heatsink blower draws power from a dedicated AC Supply Source for Heatsink Blower of 220 VAC, enabling efficient heat dissipation without external fans. This configuration enhances reliability and minimizes maintenance intervals in high-duty machining cycles.

Engineered for demanding spindle control, the KDA 3.1-050-3-A0S-W1 offers extensive speed range and continuous power suitable for milling, turning, and grinding operations. Its high torsional stiffness supports rapid acceleration and precise positioning, while built-in protective functions safeguard against overload and overtemperature. With its straightforward connectivity and rugged design, this spindle drive stands as a dependable solution for advanced manufacturing environments.
