KDA 3.2-150-3-LPI-W1

The KDA 3.2-150-3-LPI-W1, manufactured by Bosch Rexroth Indramat, is a precision drive from the KDA Spindle Drives series designed for demanding spindle applications. This unit delivers a Rated Current of bold 150 A and operates on a bold 300 V DC Bus Voltage, providing robust torque performance across its entire speed range. Its compact footprint features forced-air cooling via an integrated heatsink blower, ensuring stable thermal management during continuous operation. The drive’s advanced positioning control and high stiffness architecture make it well-suited for high-speed machining spindles and multi-axis milling setups.

Boasting a dedicated AC Supply Source for Heatsink Blower of bold 220 VAC, the KDA 3.2-150-3-LPI-W1 maintains optimal thermal regulation under peak loads. It supports an Aux. Encoder Input with full feedback capability for either the main spindle or a secondary motor, enhancing closed-loop accuracy. The Aux. Interface offers an bold Incremental Encoder Output that seamlessly integrates with industrial automation controllers. Its modular Design (type bold 2) and compliant Product family (model bold KDA) streamline installation and maintenance, while the SERCOS-based Speed Command Value interface ensures deterministic communication and cycle-accurate speed control.

Engineered for industrial reliability, this spindle drive’s forced-cooling scheme and precision encoder interfaces minimize thermal drift and positional error, ensuring consistent performance in continuous-duty applications. Integration into existing machine tool architectures is simplified by its standardized SERCOS interface and versatile encoder I/O, reducing commissioning time. The KDA 3.2-150-3-LPI-W1’s combination of high-current capacity, robust voltage rating, and precise motion control make it an ideal choice for CNC machining centers, high-performance lathes, and automated milling machines requiring stringent speed stability and torque precision.
