KDA 3.1-050-3-DQS-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-DQS-W1 from the KDA Spindle Drives series is engineered for precision spindle applications, featuring a Rated Current of 50 A and a DC Bus Voltage of 300 V to ensure robust continuous power delivery. This drive incorporates a Digital 16-Bit Parallel Speed Command Value for high-resolution velocity control and a dedicated Aux. Interface: Serial Interface RS 232 C for seamless communication with motion controllers. An Aux. Encoder Input for 1V Sinusoidal Enc. enables direct feedback integration, while the drive’s modular Design 1 chassis simplifies installation within compact control cabinets.

The thermal management system relies on forced cooling by heatsink blower technology, powered by an AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal temperature under heavy loads. As a member of the Product KDA family, Series 3 variants share common mechanical and electrical footprints, streamlining maintenance and spare-part inventories. Protective circuits include overcurrent and thermal overload safeguards calibrated to the drive’s 50 A rating, enhancing system resilience in rigorous machining environments.

Balancing high stiffness with fine positioning capabilities, the KDA 3.1-050-3-DQS-W1 excels in demanding spindle applications requiring wide speed ranges and constant torque output. Its combination of continuous power performance, precise encoder interfacing, and proven Bosch Rexroth Indramat reliability makes it an ideal solution for CNC machining centers, grinding spindles, and automated tooling systems.
