KDA 3.1-150-3-AP0-U1

The KDA 3.1-150-3-AP0-U1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision motion with high rigidity and dynamic responsiveness. This drive leverages advanced positioning features and an extensive speed range to meet demanding machine tool requirements. Its compact footprint and robust construction ensure seamless integration into new or existing CNC systems. Designed for both retrofit and greenfield installations, it simplifies system architecture while maximizing performance and uptime.

Engineered for heavy-duty spindle service, the unit boasts a Rated Current of 150 A and a DC Bus Voltage of 300 V, providing continuous power for sustained operation. Heat dissipation is handled by a Cooling system that is Forced Cooled by Heatsink Blower, powered via an AC Supply Source for Heatsink Blower of 115 VAC. Speed inputs are managed through a Speed Command Value of Analog +/- 10V, while the Aux. Encoder Input offers feedback for spindle or second motor monitoring. For simplified installations, the drive features no additional interface hardware, with Aux. Interface specified as "Without". The modular design (Design 1) in the Product line KDA Series 3 reduces complexity and streamlines spare-part management.

Reliability is further enhanced by forced cooling that prevents thermal overload, ensuring consistent torque delivery even under peak loads. The drive’s architecture supports direct integration into Bosch Rexroth Indramat control networks, reducing commission time and wiring effort. Ideal for milling, grinding, and turning applications, this spindle drive delivers the precise speed control and rugged durability critical for high-throughput production environments.
