KDA 3.3-100-3-DQ0-U1

The KDA 3.3-100-3-DQ0-U1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision motion control with high mechanical stiffness and a wide continuous speed range. Its architecture integrates advanced positioning features and dynamic response, ensuring spindle speed regulation remains stable under varying loads. With a compact footprint and modular design, it adapts easily to both retrofit and new-machine applications. Engineered for demanding production environments, this drive combines performance and durability in one package.

Incorporating a DC Bus Voltage of 300 V and a continuous Rated Current of 100 A, the drive sustains high torque output across its entire operating envelope. The unit employs Cooling via a Forced Cooled by Heatsink Blower system powered by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal thermal conditions even under peak load. Speed is controlled through a Speed Command Value input using a Digital 16-Bit Parallel interface, while position feedback is supported by an Aux. Encoder Input for 1V Sinusoidal Enc.. The drive’s Aux. Interface configuration is factory-set Without, simplifying the I/O layout, and its core is built around a robust Design 3 topology within the Product KDA family for reliable performance.

Seamless integration with established CNC controls and PLC networks accelerates commissioning and diagnostics, reducing setup time. The drive’s forced-air cooling and rugged construction ensure consistent operation in harsh industrial settings, minimizing unplanned downtime. Ideal for milling spindles, drilling heads, and high-speed grinding applications, the KDA 3.3-100-3-DQ0-U1 provides dependable, precise spindle drive functionality for advanced manufacturing systems.
