KDA 3.2-050-3-A00-U1

The Bosch Rexroth Indramat KDA 3.2-050-3-A00-U1 is a high-performance drive controller in the KDA Spindle Drives series, designed to deliver precision control and robust power for spindle applications. Manufactured by Bosch Rexroth Indramat, this controller features a Current Rated value of 50 A and a Continuous Current rating of 35 A, supporting demanding spindle loads with consistent performance. Its primary function is to provide reliable speed regulation and torque management for main spindle drives in machine tools, ensuring smooth operation across a wide range of speeds and loads.

In terms of technical specifications, the KDA 3.2-050-3-A00-U1 operates at a Rated Voltage of 300 V and offers a dedicated Rated Connection Voltage for attached Blower of AC 50–60 Hz. Speed control is achieved via an Analog +/- 10V Speed Command Value input, allowing for fine adjustment of spindle rpm with high resolution. The drive’s internal design (Product: KDA, Series: 3, Design: 2) integrates a heatsink blower for forced cooling, effectively dissipating heat generated under heavy loads and maintaining stable thermal conditions. Notably, the controller is supplied without an auxiliary encoder interface (Aux. Encoder Input: WithoutAux. Interface1), simplifying the configuration for applications that do not require additional feedback channels.

Beyond its core performance, the KDA 3.2-050-3-A00-U1 excels in compatibility and efficiency. The standardized analog command interface ensures seamless integration with a variety of CNC systems and PLCs, while the forced cooling mechanism enhances durability by preventing thermal overload during prolonged operation. The controller’s ability to maintain continuous power delivery at 35 A and peak response at 50 A makes it exceptionally suited for high-stiffness, precision positioning tasks. Designed to meet industrial demands, this drive controller offers improved uptime, reduced maintenance, and enhanced spindle stability, delivering tangible benefits in productivity and machining quality across diverse manufacturing environments.
