KDA 3.2-050-3-L0S-U1

KDA 3.2-050-3-L0S-U1, Bosch Rexroth Indramat, KDA Spindle Drives represents a robust main spindle drive solution designed for high-stiffness applications and precision positioning. This unit delivers continuous power across an extensive speed range, making it ideally suited for demanding machining and milling operations. Built with a durable enclosure and advanced power electronics, the drive ensures consistent spindle performance under heavy loads. With a modular footprint, it seamlessly integrates into both new system designs and retrofit projects, reducing engineering lead time.

Equipped with a DC Bus Voltage of 300 V and a Rated Current of 50 A, the KDA 3.2-050-3-L0S-U1 sustains high torque output while maintaining thermal stability. Forced cooling is provided by a Cooling system featuring a Heatsink Blower, which draws its power from an AC Supply Source for Heatsink Blower rated at 115 VAC. The drive implements a Speed Command Value via a SERCOS - Interface, enabling deterministic, jitter-free speed control and network integration. For communication and status monitoring, it offers an Aux. Interface through Serial Interface RS 232 C and supports diagnostics even when the Aux. Encoder Input is specified as Without. Internally, the drive adheres to a Design classification of 2, reflecting its compliance with industry safety and performance standards.

Integration of the KDA 3.2-050-3-L0S-U1 into OEM automation platforms is streamlined by standardized mounting dimensions and fieldbus compatibility. Its forced-air heatsink blower dramatically enhances reliability in continuous-duty cycles, reducing the risk of thermal shutdown and unscheduled stops. Whether deployed in high-speed spindles, grinding machines, or multi-axis machining centers, this spindle drive delivers consistent precision, exceptional uptime, and simplified maintenance.
