KDA 3.3-050-3-DYI-U1

The Bosch Rexroth Indramat KDA 3.3-050-3-DYI-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision motion control with robust power handling. It features a Rated Current of 50 A and a DC Bus Voltage of 300 V, providing consistent torque for demanding spindle applications. This drive employs a Design: 3 frame within the Product: KDA family and carries the designation Series: 3 to denote its integration in high-performance CNC and milling systems. Compact yet sturdy, the unit’s architecture simplifies panel layouts while ensuring reliability under continuous operation.

Thermal management is assured through Cooling: Forced Cooled by Heatsink Blower powered by an AC Supply Source for Heatsink Blower: 115 VAC, guaranteeing stable junction temperatures during peak loads. Motion feedback and synchronization are enabled via the Aux. Encoder Input: With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) and complemented by an Aux. Interface: Incremental Encoder Output for precise position tracking. Command integration leverages a Speed Command Value: Digital 16-Bit Parallel interface, streamlining indexing routines and enhancing responsiveness in rapid acceleration profiles.

Engineered for splice-free performance, the KDA 3.3-050-3-DYI-U1 spindle drive balances high stiffness and low noise for superior surface finishes. Its modular wiring terminals and standardized mounting dimensions shorten installation times, while the robust electronic topology supports extended service intervals. Ideal for high-speed milling, grinding, and drilling tasks, this spindle drive forms the cornerstone of advanced machining centers requiring exacting speed control and continuous power delivery.
