KDA 3.2-150-3-A0S-W1

The Bosch Rexroth Indramat KDA 3.2-150-3-A0S-W1 drive controller from the KDA Spindle Drives series delivers precision control and robust performance with a Rated Voltage of 300 V and a Current Rated of 150 A. Engineered as part of the modular Product KDA platform, this Series 3 device in Design 2 features a Continous Current of 90 A and supports an external cooler via a Rated Connection Voltage for attached Blower of AC 50–60 Hz. Featuring seamless integration into CNC architectures, the controller’s compact footprint and advanced electronics simplify system design. Built and tested in Germany, it upholds Rexroth Indramat’s legacy of durability and high-precision automation technology.

The controller employs an analog input scheme with a Speed Command Value of Analog +/– 10 V for ultra-responsive speed regulation across the full operating range. A dedicated Aux. Encoder Input of WithoutAux. Interface1 ensures tight feedback loops for asynchronous and frameless spindle motors. Active thermal management is driven by a rear-mounted blower, while embedded microcontroller logic continuously monitors rotor position and adjusts current delivery in real time. Comprehensive fault detection routines safeguard against overcurrent, undervoltage, and thermal overload conditions to maintain uninterrupted spindle operation.

Optimized for CNC milling, turning, and grinding centers, the KDA 3.2-150-3-A0S-W1 offers flexible parameterization and scalable expansion through additional IndraDrive control modules. Its reliable performance under high dynamic loads and precise current control makes it ideal for sectors demanding repeatable high-speed machining accuracy. This drive controller represents a cost-effective, future-ready solution for advanced automation applications.
