KDA 2.1-150-3-A0S-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-A0S-W1 from the KDA Spindle Drives series delivers precision motion control with a rated current of 150 A and a DC Bus Voltage of 300 V. This main spindle drive offers high stiffness and fine positioning capabilities across an extensive speed range, making it ideal for demanding machining applications. The drive’s robust design 1 chassis ensures mechanical stability under dynamic loads, while the integrated heatsink blower maintains optimal thermal conditions. Engineers benefit from seamless parameterization and reliable performance across the entire operating envelope.

The unit features a forced cooled by heatsink blower thermal system powered by a standard AC Supply Source for Heatsink Blower: 220 VAC, ensuring consistent heat dissipation during continuous operation. Control signals are handled via an analog +/- 10V Speed Command Value input, providing accurate velocity referencing for spindle acceleration and deceleration profiles. Communication and diagnostics are supported through the built-in Aux. Interface: Serial Interface RS 232 C, while the Aux. Encoder Input: Without option simplifies installation in applications that rely on sensorless control. As part of the series 2 KDA family, the drive is fully compatible with related modules, and the product: KDA platform streamlines maintenance and firmware updates.

Designed specifically for main spindle duties, this drive combines continuous power delivery with quick-reacting control loops to optimize cycle times and surface finish quality. Its forced-air cooling arrangement and high current capacity make it a reliable choice for high-speed machining centers, lathes, and multi-axis milling machines requiring consistent torque and speed regulation.
