KDA 3.1-100-3-D0D-W1

The KDA 3.1-100-3-D0D-W1, Bosch Rexroth Indramat, KDA Spindle Drives – the main spindle drive brings precision motion with robust power delivery. Engineered for high-stiffness spindle control, it offers a broad speed range and advanced positioning capabilities. The drive’s compact design integrates seamlessly into machining centers, ensuring minimal cabinet space while retaining service accessibility. With a forced-air cooling scheme, it maintains consistent performance even under continuous heavy load.

The drive’s core specifications deliver exceptional operational stability: it handles a Rated Current of 100 A and sustains a DC Bus Voltage of 300 V for demanding spindle tasks. Cooling is managed via a Forced Cooled by Heatsink Blower system powered from an AC Supply Source for Heatsink Blower of 220 VAC, providing efficient thermal control. The Aux. Interface accepts a Position Command Value Digital 16-Bit Parallel input, and the drive features a Speed Command Value in the same Digital 16-Bit Parallel format. With an Aux. Encoder Input configuration set to Without, the unit streamlines integration where encoder feedback is handled externally. The drive’s Design designation of 1 and Product family identifier of KDA ensure compatibility with existing Bosch Rexroth Indramat modules, minimizing engineering overhead and spare parts inventory.

Integration into multi-axis CNC systems is straightforward thanks to the standardized command interfaces and compact footprint. The robust forced-cooling blower and high bus voltage margin deliver reliable operation in high-duty-cycle applications, reducing thermal derating and unplanned downtime. Ideal for precision milling, turning, and grinding centers, the KDA 3.1-100-3-D0D-W1 spindle drive provides the reliability and performance necessary for modern machine tool builders.
