KDA 3.1-150-3-A0D-W1

KDA 3.1-150-3-A0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives delivers a powerful solution for precision main spindle control in demanding machining applications. Engineered for high stiffness and dynamic positioning, this drive supports a broad speed range with continuous power delivery under heavy loads. The unit integrates sophisticated control algorithms to maintain torque stability and minimize vibration, ensuring consistent surface finish and dimensional accuracy. Designed for seamless retrofit or green-field installations, it conforms to industry safety standards while maximizing uptime.

Incorporating key specifications, the drive accepts a DC Bus Voltage of 300 V and outputs a Rated Current of 150 A for robust spindle acceleration. Thermal management relies on a Cooling system comprising a forced-air heatsink blower powered by a AC Supply Source for Heatsink Blower of 220 VAC, guaranteeing reliable heat dissipation during continuous operation. Command interfaces include an Aux. Interface for Position Command Value Digital 16-Bit Parallel signals and an analog Speed Command Value of +/- 10V, while the Aux. Encoder Input option is specified as Without for streamlined configuration. The drive’s internal Design (version 1) and product family designation KDA underscore its modular architecture, allowing easy field servicing and component exchange.

Bosch Rexroth Indramat’s KDA 3.1-150-3-A0D-W1 excels in systems requiring tight integration with CNC controls and feedback loops, offering plug-and-play compatibility with industry-standard interfaces. Its fan-based forced cooling enhances reliability under peak loads, and its high-current capability suits heavy-duty spindles in milling, drilling, and grinding centers. By combining precise analog speed control with rugged thermal design, this spindle drive secures long service life and optimal machining performance in even the most strenuous production environments.
