KDA 3.1-150-3-A0S-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-A0S-W1 from the KDA Spindle Drives series is a precision-engineered main spindle drive designed to meet demanding industrial requirements. With a Rated Current of 150 A and a DC Bus Voltage of 300 V, this drive delivers consistent power and torque across a wide speed range. The drive’s Cooling is implemented via a Forced Cooled by Heatsink Blower mechanism, backed by an AC Supply Source for Heatsink Blower of 220 VAC. Its Speed Command Value interface supports Analog +/- 10V control signals, ensuring smooth acceleration and deceleration profiles.

Performance and reliability are reinforced through a robust Aux. Interface via Serial Interface RS 232 C and a simplified Aux. Encoder Input without additional cabling complexity. The unit’s Design 1 configuration and Product KDA designation guarantee compatibility with existing Indramat infrastructure. Built within the Series 3 platform, the drive offers an integrated solution for high-stiffness spindle control. Each component is selected for thermal stability and EM noise immunity, minimizing downtime in harsh manufacturing environments.

Installation and commissioning are streamlined by the drive’s standardized footprint and comprehensive technical documentation. The KDA 3.1-150-3-A0S-W1 excels in applications requiring rapid positioning and dynamic speed changes, such as milling, grinding, and drilling spindles. Its precise analog command interface, combined with forced heatsink blower cooling, ensures continuous operation under heavy duty cycles without derating, making it an ideal choice for high-performance machining centers and specialized automation systems.
