KDA 3.2-150-3-L00-W1

KDA 3.2-150-3-L00-W1, Bosch Rexroth Indramat, KDA Spindle Drives marks a milestone in spindle drive controllers by integrating high-performance regulation with robust build quality. The unit delivers a Current Rated capacity of 150 A alongside a Continous Current rating of 90 A, ensuring precise handling of dynamic loads. Featuring a Rated Voltage of 300 V and a standardized Rated Connection Voltage for attached Blower of AC 50–60, it harmonizes seamlessly with industrial power supplies. Its modular Design (Version 2) supports straightforward maintenance and future-proof upgrades.

In terms of detailed specifications, the controller leverages a Speed Command Value interface via SERCOS - Interface for deterministic motion control and ultra-low latency communication. An Aux. Encoder Input configured as WithoutAux. Interface1 simplifies feedback wiring for the main spindle application. The embedded heatsink blower forces cooling through an optimized airflow path, sustaining thermal stability under peak loads. With a compact unit footprint and standardized connection scheme, the drive ensures consistent performance across the full operating range.

Engineers will appreciate the KDA 3.2-150-3-L00-W1’s straightforward integration into existing CNC and PLC ecosystems, bolstered by native compatibility with Bosch Rexroth Indramat toolchains. Its proven reliability under high-stiffness spindle applications reduces vibration and increases positional accuracy, translating to higher throughput and reduced wear. Overall, the drive excels in demanding milling, turning, and drilling centers where uptime and precision are critical.
