KDA 3.1-150-3-D0S-W1

KDA 3.1-150-3-D0S-W1, Bosch Rexroth Indramat, KDA Spindle Drives delivers a robust spindle control solution with a continuous Rated Current of 150 A and a DC Bus Voltage of 300 V for demanding machining and milling applications. Its high rigidity design ensures minimal torsional compliance, while the extensive speed range supports seamless transitions between low-speed indexing and high-speed cutting operations. Optimized for precision, the drive’s feedback loop leverages a digital architecture to maintain torque stability under dynamic loads. Forced cooling by an integrated heatsink blower further stabilizes thermal performance during extended runtime.

Boasting a Cooling system specified as Forced Cooled by Heatsink Blower, the drive uses a dedicated AC Supply Source for Heatsink Blower at 220 VAC to ensure consistent heat dissipation. The onboard Aux. Interface is a Serial Interface RS 232 C for parameterization and diagnostics, while the Aux. Encoder Input is provided as Without, simplifying electrical connections in retrofit scenarios. The drive’s Speed Command Value interface is a Digital 16-Bit Parallel bus, granting microsecond-level response for real-time speed adjustments. Classified under Design "1" and coded as Product "KDA" in the Series "3", this spindle module integrates seamlessly with existing Rexroth controllers and PLC networks, preserving engineering standards and reducing wiring complexity.

Designed for high-precision machine tools, the KDA 3.1-150-3-D0S-W1 drive offers reliable operation under continuous loads and transient peak demands. Its modular architecture streamlines integration into multi-spindle setups, delivering consistent torque delivery even in synchronized configurations. Engineers benefit from reduced commissioning times and proven Rexroth Indramat reliability, making this spindle drive an ideal choice for metal cutting, milling, and grinding centers where uptime and accuracy are paramount.
