KDA 2.1-050-3-AP0-W1

The Bosch Rexroth Indramat KDA 2.1-050-3-AP0-W1 from the KDA Spindle Drives series by Bosch Rexroth Indramat delivers precise motion control with a Rated Current of 50 A and a DC Bus Voltage of 300 V. Engineered for high stiffness and dynamic positioning, this spindle drive provides an extensive speed range with continuous power output. As part of the KDA Series (Product: KDA, Design: 1, Series: 2), it ensures seamless integration into existing machine tool architectures. Its compact form factor belies the robust performance required for demanding milling, grinding, and drilling applications.

Featuring advanced thermal management, the drive is Forced Cooled by Heatsink Blower using an AC Supply Source for Heatsink Blower: 220 VAC to maintain optimal junction temperatures under heavy spindle loads. The Speed Command Value: Analog +/- 10V interface enables fine velocity regulation, while the Aux. Encoder Input: With for Spindle or Second Motor Feedback supports dual-loop control for enhanced accuracy. Although it lacks an Aux. Interface, the KDA 2.1-050-3-AP0-W1 leverages industry-standard signal protocols to streamline commissioning. This configuration ensures rapid response to load variations and minimizes overshoot during high-frequency cutting operations.

Built upon the proven KDA platform, the drive’s forced cooling and encoder feedback architecture deliver stable performance across a wide operational envelope. Its combination of 300 V DC Bus Voltage and 50 A Rated Current capacity supports high-torque spindle motors without compromise. The KDA 2.1-050-3-AP0-W1 sets the benchmark for reliability in CNC machining centers, tool grinders, and precision manufacturing lines where uninterrupted uptime and repeatable motion are paramount.
