KDA 3.1-100-3-D0D-U1

KDA 3.1-100-3-D0D-U1 from Bosch Rexroth Indramat is a high-performance module in the KDA Spindle Drives lineup, engineered to deliver precision motion control for demanding spindle applications. The drive’s compact form factor houses robust power electronics optimized for continuous operation, ensuring consistent torque delivery and rapid acceleration profiles. Featuring adaptive control algorithms, the unit maintains optimal stiffness across its extensive speed range, making it equally suited for machining centers and milling spindles. Integrated diagnostics and status monitoring provide real-time system visibility, simplifying commissioning and maintenance.

Built around a Design 1 chassis, the drive accepts a DC Bus Voltage of 300 V and supplies a Rated Current of 100 A for sustained spindle torque. A dedicated AC Supply Source for Heatsink Blower at 115 VAC ensures reliable thermal management via Cooling forced by Heatsink Blower, preventing derating under heavy duty cycles. Position feedback is managed through an Aux. Interface Position Command Value Digital 16-Bit Parallel connection, while motion commands utilize a Speed Command Value Digital 16-Bit Parallel input for sub-microsecond response. The module is specified as Aux. Encoder Input Without, streamlining integration into systems that rely on centralized encoder processing, and is designated Series 3 to match legacy KDA installations.

Engineers will appreciate the drive’s plug-and-play compatibility with existing Indramat bus systems and its hardened power stage for uninterrupted spindle operation. The forced-cooling architecture and high overload tolerance translate into exceptional reliability even in high-duty environments. When paired with Rexroth CNC controls or third-party automation platforms, the KDA 3.1-100-3-D0D-U1 delivers professional-grade precision and uptime for advanced metalworking, drilling, and grinding applications.
