KDA 3.2-050-3-DPI-W1

The Bosch Rexroth Indramat KDA 3.2-050-3-DPI-W1 from the KDA Spindle Drives series delivers robust spindle performance with a Rated Current of 50 A and a DC Bus Voltage of 300 V. Engineered as Product KDA in Design 2 and designated Series 3, this main spindle drive integrates a Digital 16-Bit Parallel Speed Command Value for precise motion control. The drive is Forced Cooled by Heatsink Blower and relies on an AC Supply Source for Heatsink Blower of 220 VAC to maintain optimal operating temperatures. Compact yet powerful, it pairs industrial rigidity with advanced digital command architecture.

Featuring a high-stiffness design and extensive speed range, the KDA 3.2-050-3-DPI-W1 offers seamless positioning and continuous power delivery. The Aux. Encoder Input for Spindle or Second Motor Feedback ensures accurate real-time monitoring, while the Aux. Interface as Incremental Encoder Output supports easy integration with existing feedback systems. Forced cooling via the heatsink blower sustains performance under heavy-duty cycles, and the drive’s digital topology reduces electrical noise and optimizes dynamic response. These features combine to minimize vibration, improve spindle accuracy, and enhance overall system stability.

Designed for demanding machining centers, the KDA drive excels in applications requiring high rigidity and uninterrupted power. Its modular construction simplifies maintenance, and the robust cooling arrangement guards against thermal overload during prolonged operation. With factory-configured digital speed control and versatile encoder interfaces, the drive delivers precise, reliable spindle automation for advanced manufacturing environments.
