KDA 3.1-150-3-LPI-W1

The Bosch Rexroth Indramat KDA 3.1-150-3-LPI-W1 from the KDA Spindle Drives series offers precision spindle control with a rated current of 150 A and a DC Bus Voltage of 300 V. Designed for demanding machining applications, this Product KDA drive integrates a Design 1 housing optimized for rigidity and thermal management. It features a native SERCOS - Interface Speed Command Value pathway and supports an Aux. Encoder Input for spindle or secondary motor feedback. Powering the heatsink blower through a dedicated AC Supply Source for Heatsink Blower at 220 VAC ensures continuous operation under heavy loads.

The drive’s electronic architecture provides an Aux. Interface with Incremental Encoder Output for high-resolution position monitoring and closed-loop servo control. Cooling is handled by a robust Forced Cooled by Heatsink Blower system that maintains optimal junction temperatures during extended cycles. With its scalable Series 3 design, the unit accommodates a broad speed range while delivering consistent torque and stiffness for precision milling and grinding. Integration of regenerative energy absorption and fault diagnostics enhances system reliability and reduces downtime.

Installation and commissioning are streamlined with standardized mounting footprints and plug-and-play wiring harnesses. Maintenance intervals are extended by proactive temperature and current monitoring, while support for multi-axis synchronization simplifies complex machine architectures. The KDA 3.1-150-3-LPI-W1 spindle drive combines advanced control features with rugged build quality to deliver high-performance spindle operation in modern CNC and industrial automation environments.
