KDA 3.3-050-3-A00-W1

The Bosch Rexroth Indramat KDA 3.3-050-3-A00-W1 from the KDA Spindle Drives series combines precision engineering with robust performance in a compact AC spindle drive controller. It delivers a current rated of 50 A and a continuous current of 35 A, ensuring steady power delivery under varying load conditions. The unit operates at a rated voltage of 300 V and features a rated connection voltage for attached blower of AC 50–60 Hz for reliable cooling in demanding applications. Configurable via onboard EEPROM parameters, this controller adapts effortlessly to diverse motor types and application demands.

Inside the controller, the Product: KDA core is complemented by a Series: 3 and Design: 3 architecture, integrating a three-phase power transformer, KDV modular power supply, and a CDM computer drive module. The drive accepts a speed command value of Analog +/- 10 V for precise speed regulation and features an aux. encoder input without Aux. Interface1 for streamlined feedback integration. Protection against thermal overload is provided by a thermistor interface linked to an overload detector, safeguarding the system during peak operation periods.

Engineered for seamless cabinet integration, the KDA 3.3-050-3-A00-W1 is equipped with coordinated power electronics and an asynchronous spindle motor module. Its modular design simplifies maintenance and allows for easy scaling of drive capacity by adding KDV modules as required. This spindle drive controller is an ideal solution for high-precision machining, milling spindles, and dynamic automation systems demanding consistent torque and speed accuracy.
