KDA 3.2-150-3-DYS-U1

The Bosch Rexroth Indramat KDA 3.2-150-3-DYS-U1 from the KDA Spindle Drives series and manufactured by Bosch Rexroth Indramat combines high stiffness, precise positioning features, and an extensive speed range. It delivers a continuous performance envelope driven by a Rated Current of 150 A and a DC Bus Voltage of 300 V for demanding spindle applications. The drive’s Product designation KDA and Design class 2 underscore its optimized architecture for rigidity and repeatable motion control. An integrated Speed Command Value interface supports a Digital 16-Bit Parallel setpoint for ultra-fine velocity regulation.

Thermal management is assured through a Cooling method: Forced Cooled by Heatsink Blower powered via an AC Supply Source for Heatsink Blower: 115 VAC, maintaining stable junction temperatures under heavy loads. Connectivity is enhanced by an Aux. Interface: Serial Interface RS 232 C and an Aux. Encoder Input: With Auxiliary and Synchronous Inputs (Due to AS 35 and Speed Command Value = A), facilitating closed-loop feedback and remote diagnostics. The drive is catalogued under Series 3, ensuring compatibility with legacy KDA system components and simplifying upgrade paths. This combination of interfaces and cooling provisions makes it a turnkey solution for high-dynamics spindle control.

Engineered for machine tool builders, the KDA 3.2-150-3-DYS-U1 excels in applications requiring rapid acceleration, high torque density, and minimal drift. Its robust construction and standardized connections reduce commissioning time, while the precision of the Digital 16-Bit Parallel Speed Command and synchronous encoder feedback guarantee repeatable cycle-to-cycle accuracy. With its balance of power, control, and thermal stability, this spindle drive is ideal for milling, grinding, and high-speed finishing operations.
