KDA 3.2-050-3-D0I-U1

KDA 3.2-050-3-D0I-U1, Bosch Rexroth Indramat, KDA Spindle Drives is a high-performance main spindle drive engineered for precision machining and high-stiffness applications. The drive delivers a continuous Rated Current of 50 A from a robust DC Bus Voltage of 300 V, enabling rapid acceleration and stable speed control across a broad RPM range. Its compact footprint and modular interface make it an ideal choice for machine tool builders seeking scalable spindle drive solutions. Advanced positioning features ensure that positional accuracy and repeatability are maintained under dynamic load conditions.

Incorporating a forced-cooling architecture with a dedicated Cooling module, the unit relies on a Heatsink Blower powered by an AC Supply Source for Heatsink Blower of 115 VAC for efficient thermal management. Command inputs are handled via a Speed Command Value of Digital 16-Bit Parallel, offering fine resolution and low-latency response. Connectivity is facilitated through an Aux. Interface featuring an Incremental Encoder Output, while the Aux. Encoder Input is specified as Without to streamline installation. The drive’s construction follows Design standard “2” guidelines and is designated Series “3” within the Product family, reflecting its role as a Versatile KDA module.

Engineered for seamless integration into multi-axis machining centers, the KDA 3.2-050-3-D0I-U1 delivers industry-leading reliability and uptime through forced cooling and digital command processing. Its robust design minimizes maintenance intervals, while its precise current and voltage regulation support demanding cutting operations. Ideal for high-speed spindles in milling, drilling, and grinding applications, this drive enhances machine tool performance and productivity.
