KDA 2.1-050-3-L0D-U1

The Bosch Rexroth Indramat KDA 2.1-050-3-L0D-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat combines precision engineering with robust construction, featuring a product KDA design and series designation 2. This spindle drive delivers a rated current of 50 A at a DC Bus Voltage of 300 V to sustain continuous operation under high load. Control is achieved through a native Speed Command Value: SERCOS - Interface and a dedicated Aux. Interface: Position Command Value Digital 16-Bit Parallel, ensuring deterministic communication with minimal latency. The unit’s compact chassis (design 1) integrates forced cooling via a heatsink blower and draws its blower power from a dedicated AC Supply Source for Heatsink Blower: 115 VAC input.

Performance is underpinned by high stiffness and advanced positioning functions, making the KDA 2.1-050-3-L0D-U1 ideal for demanding spindle applications. A Cooling: Forced Cooled by Heatsink Blower schema manages heat rejection efficiently, while the absence of an Aux. Encoder Input: Without connector simplifies wiring in standardized machine tool installations. The drive’s intelligent thermal management and robust power stage extend torque stability across an extensive speed range, delivering consistent spindle dynamics for milling, drilling, and grinding processes. With integrated fault diagnostics and automatic current regulation, motor wear is minimized and service intervals are extended.

Designed for seamless integration into CNC controls and SERCOS networks, the KDA main spindle drive supports rapid commissioning and tool change cycles. Its combination of 300 V DC Bus Voltage, 50 A rated current, and precision digital interfaces ensures reliable, high-speed spindle control for modern machine tools seeking both rigidity and accuracy.
