KDA 3.1-150-3-LYS-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-LYS-W1 from the KDA Spindle Drives series delivers precision spindle control in the Product Family KDA with a robust Rated Current of 150 A and a stable DC Bus Voltage of 300 V. This drive, designated by Design Number 1, integrates seamless command and feedback pathways through the Speed Command Interface SERCOS for deterministic motion synchronization. With its compact footprint and modular design, the unit embodies the high-stiffness spindle drive architecture expected from Bosch Rexroth Indramat. Engineers will appreciate the comprehensive connectivity and performance tuning available out of the box.

The KDA 3.1-150-3-LYS-W1 features an Auxiliary Encoder Input supporting both synchronous and auxiliary signals, enabling precise position feedback and multi-loop control. An Auxiliary Interface RS-232C serial port simplifies setup, diagnostic access, and firmware updates without interrupting production. Thermal management is handled by a Cooling Method Forced (heatsink blower) that draws air across power components, while a dedicated Heatsink Blower Supply 220 VAC ensures continuous high-power operation under challenging machine-room conditions. Network integration and safety functions are easily configured via industry-standard SERCOS protocols.

Optimized for continuous and dynamic spindle workloads, the KDA drive sustains high torque at low speeds and wide acceleration profiles. Forced cooling and sturdy mechanical construction maintain temperature and vibration stability, supporting consistent cycle times and extended maintenance intervals. Ideal for milling, grinding, and advanced machining centers, the KDA 3.1-150-3-LYS-W1 represents a turnkey spindle drive solution where reliability and precision are paramount.
