KDA 3.3-100-3-A00-U1

KDA 3.3-100-3-A00-U1, Bosch Rexroth Indramat, KDA Spindle Drives drive controller combines robust construction with precise positioning features to deliver reliable spindle power in demanding machining applications. The design leverages high torsional stiffness and wide speed range capabilities to optimize dynamic response and surface finish quality. An integrated heatsink blower provides forced cooling to maintain thermal stability under continuous operation. Advanced control interfaces simplify integration with CNC systems and motion controllers.

Engineered for heavy-duty spindle tasks, the controller sustains a Current Rated capacity of 100 A with a Continous Current rating of 70 A. It operates on a Rated Voltage of 300 V via a dedicated Rated Connection Voltage for attached Blower of AC 50–60. The unit’s Series designation is 3 and its Design classification is 3, ensuring compatibility with existing KDA modules. A precision Speed Command Value interface of Analog +/- 10V enables fine-tuned velocity control, while the Aux. Encoder Input without auxiliary interface preserves high signal integrity.

Seamless integration into multi-axis spindles and modular machine platforms is facilitated by its compact form factor and standardized mounting. The forced-air heatsink blower enhances reliability by preventing overheating during prolonged cycles. Ideal for lathes, milling centers, and grinding machines, the KDA 3.3-100-3-A00-U1 drive controller delivers consistent performance, reduced downtime, and simplified maintenance in high-throughput production environments.
