KDA 3.1-100-3-A0D-U1

KDA 3.1-100-3-A0D-U1, Bosch Rexroth Indramat, KDA Spindle Drives delivers precision spindle control in a compact, robust package. This main spindle drive is engineered for high stiffness and dynamic positioning, supporting uninterrupted operation in demanding CNC and milling applications. Its integrated control electronics provide seamless speed regulation and high-resolution feedback management. The drive’s modular architecture simplifies installation and maintenance, minimizing downtime in automated machine tools.

Designed around a 300 V DC Bus Voltage and a 100 A Rated Current, the unit ensures ample torque for heavy-duty spindles. Cooling is handled by a Forced Cooled by Heatsink Blower system powered from an 115 VAC AC Supply Source for Heatsink Blower, maintaining optimal thermal stability under peak loads. Command signals are accepted via an Analog +/-10V Speed Command Value input, while positional data flows through a Position Command Value Digital 16-Bit Parallel Aux. Interface. The drive conforms to Design 1 standards within Series 3 of the KDA product line. Note that the Aux. Encoder Input is provided Without prewired encoder sockets, allowing custom integration with encoder modules.

Engineers appreciate the drive’s flawless integration into Bosch Rexroth CNC ecosystems, leveraging native control profiles for spindle synchronization and spindle load monitoring. Its forced-air cooling blower and compact heat sink assure long-term reliability even in high-duty machining cycles. The KDA 3.1-100-3-A0D-U1 excels in applications requiring consistent speed holds, rapid accelerations, and precise torque control, from high-speed drilling to heavy roughing operations.
