KDA 3.1-100-3-DQI-W1

The Bosch Rexroth Indramat KDA 3.1-100-3-DQI-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a Rated Current of 100 A and a robust DC Bus Voltage of 300 V. This main spindle drive features a Digital 16-Bit Parallel Speed Command Value interface for high-resolution speed regulation and an Incremental Encoder Output as the primary Aux. Interface. The drive’s Design 1 configuration and Product KDA lineage ensure seamless integration into existing machine tool ecosystems. With native support for an Aux. Encoder Input for 1V Sinusoidal Enc., it enables accurate feedback loops and reduces positional error.

Reliability is maximized through Forced Cooled by Heatsink Blower technology, backed by a dedicated AC Supply Source for Heatsink Blower of 220 VAC that maintains optimal thermal conditions under continuous load. The drive accommodates extended duty cycles without derating, thanks to its efficient heatsink blower cooling scheme and robust construction. Integration into CNC or PLC platforms is straightforward, leveraging standard PLC communication layers alongside the drive’s detailed parameterization tools. Comprehensive diagnostics monitor current draw, bus voltage stability, and encoder signal integrity, streamlining maintenance and minimizing downtime.

Compact yet capable, the KDA 3.1-100-3-DQI-W1 is engineered for high-stiffness spindle applications, offering a broad speed range from low-speed torque to high-speed cutting regimes. Its combination of 100 A rated current, 300 V DC bus voltage, and high-resolution digital command makes it ideal for machining centers, grinding spindles, and precision milling operations.
