KDA 3.2-150-3-DY0-W1

The Bosch Rexroth Indramat KDA 3.2-150-3-DY0-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat is engineered for precision main spindle control with a DC Bus Voltage of 300 V and a Rated Current of 150 A. Its robust Design 2 chassis supports continuous output, while Forced Cooled by Heatsink Blower ensures stable thermal management under heavy loads. Integration is simplified through a Product: KDA form factor and a Series: 3 rating that aligns with established spindle drive families. The unit accepts a Speed Command Value: Digital 16-Bit Parallel interface to deliver high-resolution speed regulation across extensive operational ranges.

Driving performance and connectivity feature prominently in the KDA 3.2-150-3-DY0-W1’s architecture. An AC Supply Source for Heatsink Blower: 220 VAC offers dedicated cooling power independent of the main drive supply, optimizing heat dissipation without sacrificing system voltage stability. The drive includes an Aux. Encoder Input: With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A) that allows precise feedback synchronization, while the Aux. Interface: Without auxiliary data bus reduces complexity in control cabinet wiring. The rugged hardware is rated for industrial duty cycles and leverages a high-response command path to maintain spindle stiffness under rapid acceleration and deceleration profiles.

Installation and maintenance are streamlined thanks to a compact package footprint and modular blower assembly, enabling quick field service of the heatsink cooling module. The parallel speed command and auxiliary encoder support ensure tight loop control for demanding machining processes, boosting productivity and surface finish quality. Combined with Bosch Rexroth’s global support network, the KDA 3.2-150-3-DY0-W1 delivers a reliable, high-stiffness spindle drive solution for advanced CNC and automated manufacturing platforms.
