KDA 2.1-050-3-DYD-U1
KDA Spindle Drives
The Bosch Rexroth Indramat KDA 2.1-050-3-DYD-U1 is a robust spindle drive in the KDA Spindle Drives series designed for precision motion control. Featuring a Rated Current of 50 A and an AC Supply Source of 220 V/50–60 Hz, this drive delivers reliable power handling for demanding industrial applications. Its primary function is to regulate spindle speed and torque in CNC machines, automation cells, and high-speed rotary equipment, ensuring consistent performance and smooth operation.
Detailed technical specifications of the KDA 2.1-050-3-DYD-U1 include a Bus Voltage of 300 V and support for both auxiliary and synchronous encoder inputs to enhance motor synchronization and control accuracy. Cooling is managed via an external blower option ("W1") connected through a heatsink fan connector, complemented by large heatsink fins to maintain thermal integrity under heavy loads. The drive’s amber-colored top protective cover shields high-voltage components, while digital 16-bit parallel speed command input allows precise speed regulation.
This spindle drive is engineered for vertical panel or cabinet mounting in control cabinets, with compact Dimensions of approximately 498 × 292 × 65 mm (H × W × D) for streamlined integration in space-constrained environments. The combination of external blower cooling, sturdy protective cover, and encoder feedback support ensures durability, efficiency, and extended operational life. Ideal for industrial automation, the KDA 2.1-050-3-DYD-U1 meets the rigorous demands of high-output spindle applications, providing stable performance, reduced downtime, and enhanced process reliability.
