KDA 3.2-050-3-AP0-U1

The KDA 3.2-050-3-AP0-U1, Bosch Rexroth Indramat, KDA Spindle Drives series controller delivers precision spindle and motor power in compact form. Engineered for high-performance CNC and machining centers, it supports a continuous power range from 3 to 22 kW with a Rated Voltage of 300 V. The drive provides a Current Rated capacity of 50 A alongside a Continuous Current rating of 35 A, ensuring both peak and sustained demand are met. Its rugged packaging accommodates an external heat sink and auxiliary blower supply, optimizing thermal management in harsh environments.

Featuring an analog Speed Command Value interface of +/- 10 V and an integrated Aux. Encoder Input for spindle or secondary motor feedback, the controller achieves sub-millisecond response for dynamic load changes. The Rated Connection Voltage for attached Blower at AC 50–60 Hz powers the dedicated cooling fan independent of the main drive supply, preserving bus stability. Internal diagnostics continuously monitor winding currents, bus voltage and temperature, while a modular design allows faulted submodules to be swapped without full system shutdown. The controller’s Design 2 layout and plug-in power modules streamline installation in compact cabinets.

Integration into existing Rexroth Indramat networks is seamless, leveraging native compatibility with KDA Series command modules and CNC controls. The robust thermal management – combining external heat sink conduction with a self-contained blower – maximizes uptime under sustained load. Overall, the KDA 3.2-050-3-AP0-U1 drive controller offers high reliability, precise motor synchronization, and straightforward serviceability for demanding spindle applications.
