KDA 3.2-100-3-A00-W1

The KDA 3.2-100-3-A00-W1 Drive Controller from Bosch Rexroth Indramat is part of the KDA Spindle Drives series and delivers precision motion control for demanding spindle applications. It operates on a Rated Voltage of 300 V DC bus, ensuring stable power delivery across the entire operating range. The controller provides a Current Rated of 100 A peak output and sustains a Continous Current of 70 A for extended duty cycles under full load. Command inputs are handled via an Analog +/- 10V Speed Command Value and feedback is supported by an Aux. Encoder Input: WithoutAux. Interface1, enabling accurate speed and position regulation.

Featuring a modular design (Product: KDA, Series: 3, Design: 2), the unit allows rapid field servicing and streamlined upgrades without disrupting system uptime. The integrated heat sink is paired with a separate blower module powered at Rated Connection Voltage for attached Blower: AC 50–60 Hz, effectively dissipating up to 22 kW of spindle power while maintaining allowable thermal limits. Installation is simplified through standardized mounting dimensions and plug-and-play electrical interfaces, reducing cabinet footprint and wiring complexity. Internal diagnostics continually monitor bus voltage and module temperature, providing real-time fault detection and minimizing unplanned downtime.

This spindle drive controller integrates seamlessly into CNC machining centers and automated production lines, offering repeatable performance and robust protection against overcurrent and overheating. Its rugged construction and proven control algorithms make the KDA 3.2-100-3-A00-W1 an ideal choice for high-speed milling, drilling, and precision grinding operations where reliability and accuracy are paramount. Maintenance teams benefit from its modular spare-part architecture, which accelerates repairs and keeps critical processes online.
