KDA 3.1-150-3-D00-W1

KDA 3.1-150-3-D00-W1, Bosch Rexroth Indramat, KDA Spindle Drives delivers precision motion control optimized for main spindle applications. This robust spindle drive features high stiffness mechanics and advanced positioning algorithms to maintain dynamic accuracy. It supports a continuous Rated Current of 150 A and a DC Bus Voltage of 300 V, ensuring stable power delivery across a wide speed range. The unit’s design incorporates forced cooling via an on-board heatsink blower to sustain performance under heavy loads.

Engineered for seamless integration, the drive accepts a dedicated AC Supply Source for Heatsink Blower at 220 VAC to power the cooling system independently of the main DC link. It offers a Digital 16-Bit Parallel Speed Command Value interface for deterministic speed setpoints and simplifies servo loop tuning. The module’s compact Design (Type "1") and native Product identification within the KDA family streamline installation into standardized rack systems. While no auxiliary encoder or interface slots are fitted (both Aux. Encoder Input and Aux. Interface are without), the drive leverages its high-bandwidth control electronics to directly handle feedback from integrated spindles.

Reliability and maintainability are enhanced by the forced cooling arrangement, which extracts heat efficiently to prolong component life. The compact footprint and standardized KDA package make it straightforward to integrate into CNC machine tool spindles, including milling, grinding, and turning centers. With its combination of precise digital speed command, robust current capability, and rugged thermal management, the KDA 3.1-150-3-D00-W1 drive is ideal for demanding high-precision manufacturing environments.
