The KDA 3.3-150-3-LPD-U1, Bosch Rexroth Indramat, KDA Spindle Drives unit delivers high-stiffness spindle control and precise positioning across an extensive speed range. Designed for demanding machining tasks, this drive integrates multi-layer protection and robust diagnostics to maintain process integrity. A compact power stage and optimized digital architecture ensure minimal latency between command input and motor response. Built on the proven KDA platform, it supports seamless integration in both new and retrofit installations.



Featuring a Rated Current of 150 A and a DC Bus Voltage of 300 V, the drive sustains continuous spindle power under heavy cutting loads. Forced cooling via a Heatsink Blower powered by an AC Supply Source for Heatsink Blower of 115 VAC maintains optimal junction temperatures. The native Speed Command Value interface uses SERCOS-Interface for deterministic, low-latency real-time communication. Position feedback is handled through an Aux. Encoder Input configured for spindle or secondary motor feedback, while setpoint data is delivered via an Aux. Interface with Position Command Value Digital 16-Bit Parallel format. The unit’s Design classification of 3 and Product designation "KDA" confirm its suitability for high-dynamics applications, and the Series 3 architecture supports standardized cabling and fieldbus options.



Engineered for reliability, the KDA 3.3-150-3-LPD-U1's forced-air cooling and hardened electronics endure harsh shop-floor environments while minimizing downtime. Its modular I/O and digital encoder paths simplify commissioning and expansion in multi-axis CNC systems. This spindle drive's blend of deterministic performance and rugged design makes it ideal for precision milling, drilling, and turning centers demanding sustained accuracy and throughput.
