KDA 3.1-100-3-D00-U1

The KDA 3.1-100-3-D00-U1, Bosch Rexroth Indramat, KDA Spindle Drives offers high-precision spindle control with exceptional stiffness and dynamic response. This main spindle drive delivers a continuous Rated Current of 100 A and operates on a DC Bus Voltage of 300 V, supporting demanding machining cycles across a wide speed range. Integrated positioning functions ensure micron-level accuracy, while the broad speed envelope accommodates both roughing and finishing passes. Its compact form factor simplifies cabinet layout and frees up valuable machine tool real estate.

Engineered for industrial durability, the drive features a Cooling system that is Forced Cooled by Heatsink Blower, powered by an AC Supply Source for Heatsink Blower of 115 VAC. The Speed Command Value is a Digital 16-Bit Parallel interface, delivering deterministic speed regulation. The drive’s baseline Design 1 construction ensures consistent performance, while the Product KDA topology and Series 3 architecture streamline spare-parts management. Both Aux. Encoder Input and Aux. Interface are currently specified as Without, reducing complexity for installations that rely on external feedback modules.

Integration is seamless: the drive’s standardized interface and modular design support drop-in replacement and rapid commissioning. Forced cooling and rugged construction enhance reliability in high-duty-cycle applications, minimizing unplanned downtime. Ideal for CNC spindles, grinding wheels, and high-speed tooling, the KDA 3.1-100-3-D00-U1 drive combines precision, power, and long-term uptime in a single package.
