KDA 3.1-150-3-A0S-U1

The KDA 3.1-150-3-A0S-U1, Bosch Rexroth Indramat, KDA Spindle Drives main spindle drive delivers precision spindle control with exceptional stiffness and an extensive speed range suited to high-performance machining applications. It features integrated positioning functions and continuous power output optimized for demanding CNC operations. Compact yet robust, it supports rapid acceleration and smooth torque delivery under varying loads. With a Rated Current of 150 A and a DC Bus Voltage of 300 V, this drive ensures stable motor performance and tight regulation of spindle speed.

Engineered for seamless integration, the drive relies on a 115 VAC AC Supply Source for Heatsink Blower to maintain optimal thermal performance via Forced Cooled by Heatsink Blower design. Command inputs are handled through an Analog +/– 10V Speed Command Value interface, while data exchange and diagnostics run over a Serial Interface RS 232 C Aux. Interface. The unit ships in Design version 1 of the Product family, classified under Series 3, with an Aux. Encoder Input option set to Without to simplify initial configuration.

Integration into standard CNC architectures is streamlined by the drive’s adherence to established electrical and mechanical interfaces, reducing installation time. Its forced-cooling scheme and rugged construction yield high operational reliability even under continuous heavy loads. Ideal for high-speed milling, drilling, and grinding spindles, the KDA 3.1-150-3-A0S-U1 ensures consistent throughput and minimal downtime in precision manufacturing environments.
