KDA 3.2-050-3-A0I-W1

The Bosch Rexroth Indramat KDA 3.2-050-3-A0I-W1 Drive Controller belongs to the KDA Spindle Drives series and is engineered by Bosch Rexroth Indramat. This controller is built to handle demanding spindle applications, featuring a Current Rated 50 A capacity, a Continous Current 35 A rating, and a Rated Voltage 300 V. It excels as a main spindle drive, delivering high stiffness, precise positioning functions and an extensive speed range for CNC machining centers and automated production systems.

In terms of technical specifications, the KDA 3.2-050-3-A0I-W1 operates with a DC bus voltage of 300 V and supports a forced cooling arrangement via a heatsink blower supplied at Rated Connection Voltage for attached Blower AC 50–60 Hz. The drive accepts a Speed Command Value input of Analog +/– 10 V, ensuring seamless integration with standard motion controllers. It features a robust design classified as Series 3 and Design 2, and comes without an auxiliary encoder interface (Aux. Encoder Input: WithoutAux. Interface1), simplifying the signal chain for basic spindle control tasks.

Additional features emphasize long-term reliability and compatibility within industrial environments. The drive’s forced-cooling heatsink blower and standardized AC supply frequency support continuous operation under heavy load, boosting thermal management and operational durability. Although it omits a separate auxiliary encoder interface, the analog speed command input and high current ratings make it suitable for direct connection to existing control architectures. Certified components and consistent power delivery ensure efficient spindle acceleration and deceleration profiles. Overall, the KDA 3.2-050-3-A0I-W1 enhances machining precision, reduces cycle times, and delivers reliable performance in high-speed industrial applications.
