KDA 2.1-050-3-LPI-W1

The KDA 2.1-050-3-LPI-W1, manufactured by Bosch Rexroth Indramat, belongs to the KDA Spindle Drives family and delivers robust spindle control for demanding machining applications. Engineered for high stiffness and precise positioning, it spans an extensive speed range with continuous power capability. Its compact footprint integrates seamlessly into machine tool architectures, supporting both new installations and retrofit projects. Optimized for spindle dynamics, this drive ensures stable torque delivery and rapid acceleration profiles.

In detailed specifications, the drive operates on a 300 V DC Bus Voltage platform and sustains a continuous Rated Current of 50 A at full load. Thermal management relies on Forced Cooled by Heatsink Blower Cooling, powered by a dedicated 220 VAC AC Supply Source for Heatsink Blower. Command signals are handled via a SERCOS - Interface Speed Command Value bus, while position feedback is supported through an Aux. Encoder Input configured With for Spindle or Second Motor Feedback. Auxiliary outputs include an Incremental Encoder Output Aux. Interface for synchronization with external devices. The drive’s mechanical layout adheres to Design 1 standards, reinforcing structural rigidity under high-speed operation.

Bosch Rexroth Indramat’s KDA 2.1-050-3-LPI-W1 drive delivers seamless integration with common CNC controllers and SERCOS networks, simplifying commissioning and diagnostics. The robust forced-cooling scheme and reinforced mechanical design ensure reliable performance in harsh factory environments. Ideal for precision spindle applications, it boosts overall system uptime and machining accuracy.
