The Bosch Rexroth Indramat KDA 3.1-050-3-D0S-U1 from the KDA Spindle Drives series combines precision engineering and rugged construction in a compact spindle drive platform. It delivers a Rated Current of 50 A and maintains a stable DC Bus Voltage of 300 V for continuous power output across a broad speed range. Command signals are handled via a Digital 16-Bit Parallel Speed Command Value interface, while thermal management is assured by Forced Cooled by Heatsink Blower circuitry. Integration into auxiliary systems is facilitated through a Serial Interface RS 232 C port and an AC Supply Source for Heatsink Blower of 115 VAC.
Reliability under sustained load is built into the core of the design: the robust Design 1 chassis and Product KDA architecture deliver high stiffness and precise positioning features essential for spindle applications. The absence of an Aux. Encoder Input simplifies configuration in standard deployments, while the spindle drive’s native Serial Interface RS 232 C enables remote parameter monitoring and firmware updates. Thermal resilience is heightened by the dedicated heatsink blower circuit, supported by the specified AC supply, to maintain optimal junction temperatures during heavy-duty cycles.
Ideal for high-performance machine tools, milling spindles, and automated machining centers, the KDA 3.1-050-3-D0S-U1 is engineered for long-term stability and ease of installation. Compact dimensions and standardized mounting features reduce system integration time, while the hardened design mitigates vibration and mechanical stress. Together, these attributes make this spindle drive a dependable solution for precision manufacturing environments.
