KDA 2.1-150-3-APS-W1

KDA 2.1-150-3-APS-W1, Bosch Rexroth Indramat, KDA Spindle Drives opens a new benchmark in precision spindle control. The KDA 2.1-150-3-APS-W1 unit from Bosch Rexroth Indramat’s KDA Spindle Drives family delivers high-stiffness control and extensive speed range for demanding machining tasks. Its compact footprint houses advanced power electronics designed for continuous duty, ensuring stable torque under variable loads. Engineers will appreciate its modular architecture, which simplifies retrofits and standardizes maintenance across multiple machine platforms.

Built around a robust 300 V DC Bus Voltage, this drive accepts a dedicated 220 VAC AC Supply Source for Heatsink Blower to maintain optimum thermal performance. It commands spindle velocity via an Analog +/- 10V Speed Command Value interface, while dual-loop feedback is supported through the integrated Aux. Encoder Input for spindle or secondary motor feedback. Communication and diagnostics occur over a reliable Serial Interface RS 232 C Aux. Interface, enabling real-time parameter tuning and status monitoring. The 150 A Rated Current rating ensures ample overload capacity, and the Forced Cooled by Heatsink Blower Cooling system prevents thermal derating in high-duty cycles. Internal configuration flags for Design 1, Product KDA, and Series 2 standardize part numbering and simplify spare parts management.

Integration into CNC systems is seamless thanks to the drive’s industry-proven interfaces, enabling plug-and-play setup with minimal wiring. Its forced-air cooling strategy and robust power stage deliver exceptional reliability even in harsh shop-floor environments. Ideal for main spindle applications on milling, turning, and grinding centers, the KDA 2.1-150-3-APS-W1 drive maximizes uptime, accuracy, and throughput across multiple production lines.
