KDA 3.1-050-3-AQS-W1

The KDA 3.1-050-3-AQS-W1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision motion control and high rigidity for demanding CNC and milling applications. This unit features a continuous Rated Current of 50 A and a DC Bus Voltage of 300 V, enabling sustained torque output across a broad speed range. A compact Design 1 housing integrates seamlessly into standard drive cabinets while maintaining efficient thermal performance. The drive’s compatibility with industry-standard feedback and control interfaces ensures straightforward integration into existing automation systems.

Detailed technical specifications define the KDA 3.1-050-3-AQS-W1’s capabilities: the built-in Cooling system is Forced Cooled by Heatsink Blower powered by a dedicated AC Supply Source for Heatsink Blower of 220 VAC, maintaining optimal junction temperatures under full load. Command signals are accepted via an Analog +/- 10V Speed Command Value input, and motion feedback is achieved through an Aux. Encoder Input for 1V Sinusoidal Enc. requiring minimal external signal conditioning. Connectivity is provided by a robust Aux. Interface using a Serial Interface RS 232 C, facilitating parameter configuration and diagnostics. The drive belongs to Series 3 of the KDA product family and supports the standard Product identification scheme for rapid field replacement.

Engineers appreciate the KDA 3.1-050-3-AQS-W1’s rapid commissioning and high reliability under continuous operation. Its forced-air heatsink blower and rugged construction deliver consistent performance in harsh industrial environments, reducing downtime and maintenance requirements. When paired with Rexroth motion controllers, this spindle drive enables synchronized multi-axis coordination, making it ideal for precision milling, grinding, and high-speed drilling applications.
