KDA 3.1-150-3-DQD-U1

The KDA 3.1-150-3-DQD-U1, Bosch Rexroth Indramat, KDA Spindle Drives unit delivers precision-controlled spindle operation with high stiffness and advanced positioning capabilities. This drive supports an extensive speed range while maintaining continuous power delivery, ensuring consistent performance under variable loads. An integrated heat sink blower provides forced cooling to optimize thermal management and prolong service life. Built on a compact yet robust chassis, the KDA drive simplifies installation into existing machine tool architectures.

Engineered for demanding spindle applications, the drive features a DC Bus Voltage of 300 V and a continuous Rated Current of 150 A, enabling high-torque output and rapid acceleration. Thermal regulation is handled by an onboard Cooling system that is Forced Cooled by Heatsink Blower, fed by an AC Supply Source for Heatsink Blower of 115 VAC. Commanding accuracy, the drive accepts a Speed Command Value via a Digital 16-Bit Parallel interface and supports an Aux. Interface for position control. An optional Aux. Encoder Input supplies 1 V sinusoidal feedback for closed-loop synchronization. Classified as Design 1 within the KDA product line, this module integrates directly into Bosch Rexroth control networks with minimal configuration overhead.

Optimized for seamless integration into multi-axis CNC environments, the KDA 3.1-150-3-DQD-U1 drive enhances machine tool productivity by reducing commissioning time and maintenance intervals. Its forced-cooling topology and high overload reserve deliver reliable operation in continuous-duty spindle tasks. Ideal for milling, grinding, and turning centers, this drive guarantees consistent torque under transient conditions and maximizes uptime in automated production lines.
