KDA 3.1-100-3-LPS-U1

The Bosch Rexroth Indramat KDA 3.1-100-3-LPS-U1 is a precision spindle drive from the KDA Spindle Drives series by Bosch Rexroth Indramat that delivers robust performance for demanding machining centers. This drive features a high Rated Current of 100 A and a stable DC Bus Voltage of 300 V, ensuring consistent torque under variable load conditions. The unit accepts a Speed Command Value via SERCOS interface and supports both spindle and secondary motor feedback through its auxiliary encoder input. Compact mechanical dimensions and a rugged design provide the structural rigidity required for high-precision positioning and dynamic response.

The cooling system is a forced-cooled heatsink blower powered by an AC Supply Source for Heatsink Blower of 115 VAC, maintaining optimal operating temperature even under peak load cycles. An Auxiliary Interface: Serial Interface RS 232 C allows straightforward parameterization and diagnostics, while the Aux. Encoder Input accommodates additional motor feedback channels for multi-axis synchronization. The drive’s internal construction adheres to Design 1 standards, and its integration into OEM control cabinets is simplified by the standardized Series 3 form factor. Comprehensive protective circuits and fault-detection routines minimize downtime and facilitate preventive maintenance.

Engineered for continuous and intermittent-duty spindle applications, the KDA 3.1-100-3-LPS-U1 offers a broad speed range and advanced positioning functions that optimize cycle times. Its high stiffness and low moment of inertia contribute to superior contouring accuracy in milling, grinding, and high-speed drilling processes. With its versatile feedback options and robust electrical architecture, this spindle drive is ideal for machine tool builders seeking reliability and performance in high-throughput production environments.
