KDA 3.2-150-3-A0D-U1

KDA 3.2-150-3-A0D-U1, manufactured by Bosch Rexroth Indramat, is part of the KDA Spindle Drives series designed for high-precision spindle control in demanding industrial applications. The unit delivers a 150 A rated current with a robust 300 V rated voltage front end that ensures stable operation under dynamic loads. With its forced-cooling heatsink blower, the drive maintains optimal thermal management, preventing performance degradation during extended operation. Built-in analog command functionality and streamlined design facilitate straightforward integration into existing motion-control systems.

In terms of technical specifications, this controller offers a Continous Current of 90 A and a Current Rated capacity of 150 A, ensuring ample torque availability for spindle acceleration and deceleration. The Rated Connection Voltage for attached Blower is specified as AC 50 60, providing consistent cooling airflow to the power modules. The integral Aux. Encoder Input is configured as WithoutAux. Interface1, enabling direct feedback connectivity without additional interface hardware. Series configuration is labelled as 3, while the internal Design index is 2, denoting the second-generation architecture within the KDA family. Speed references are accepted via an Analog +/- 10V Speed Command Value input, ensuring smooth and precise velocity control over the full speed range.

Engineers will appreciate the seamless integration of the KDA 3.2-150-3-A0D-U1 into CNC spindle systems, where its reliable thermal regulation and high overload headroom translate to reduced downtime and consistent cycle times. The compact footprint and forced-cooling blower simplify cabinet design while delivering high stiffness and rapid response to programming commands. Ideal for milling, grinding, and drilling operations, this drive controller enhances system reliability and uptime in high-demand production environments.
