KDA 2.1-150-3-APS-U1

The Bosch Rexroth Indramat KDA 2.1-150-3-APS-U1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precision spindle control with a Rated Current of 150 A and a DC Bus Voltage of 300 V. Designed as Product KDA, Design 1, Series 2, this drive integrates a Speed Command Value of Analog +/– 10V for smooth velocity profiling and supports an Aux. Encoder Input for Spindle or Second Motor Feedback to ensure accurate position sensing. Forced cooling is provided by a Heatsink Blower powered by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal thermal performance under heavy loads. Connectivity is seamless via the built-in Aux. Interface Serial Interface RS 232 C, enabling straightforward communication with higher-level controllers.

Built for high stiffness and extended speed ranges, the KDA 2.1-150-3-APS-U1 spindle drive offers continuous power delivery across demanding machining and grinding applications. The robust Cooling: Forced Cooled by Heatsink Blower system dissipates heat efficiently, reducing thermal drift and elongating mean time between failures. With an Aux. Encoder Input that accommodates dual feedback loops, the unit enhances dynamic response and minimizes positioning error. Field serviceability is streamlined by the modular heatsink blower assembly, while the standardized serial interface supports on-the-fly firmware updates and diagnostics.

Ideal for integration into CNC milling machines and high-precision lathes, the KDA Main Spindle Drive combines industry-leading control features with proven reliability. Its compact footprint and consistent mechanical design simplify cabinet layout and retrofitting in existing automation cells. Backed by Bosch Rexroth Indramat’s global support network, this spindle drive ensures minimal downtime and maximized throughput in any production environment.
