KDA 3.1-050-3-DY0-U1

The Bosch Rexroth Indramat KDA 3.1-050-3-DY0-U1 from the ever-reliable KDA Spindle Drives series delivers precise, high-performance spindle control with a Rated Output Current of 50 A and a DC Bus Voltage of 300 V. Engineered for demanding main spindle applications, this drive leverages a Digital 16-bit Parallel Speed Command Input for predictable, jitter-free speed regulation across a broad rpm spectrum. Its robust construction and integrated Cooling Method: Forced (Heatsink Blower) ensure consistent thermal management even under peak loads. The drive’s compact footprint, coupled with a Heatsink Blower AC Supply of 115 VAC, facilitates installation into tight machine tool cabinets without compromising service access.

Build quality is underscored by a Design Version 1 architecture that supports longtime stability and field serviceability. The unit interfaces seamlessly with both Auxiliary Encoder Inputs: Auxiliary & Synchronous for enhanced positioning accuracy and an optional Auxiliary Interface: None, enabling straightforward integration into existing CNC frameworks. As part of the Product Line: KDA, Series 3 family, it shares common mounting dimensions and parameter sets, reducing spare-parts inventories and streamlining aftermarket support. Forced cooling via an efficient heatsink blower complements the drive’s high stiffness and dynamic response, making it suitable for eco-friendly, energy-optimized machine designs.

Maintenance is simplified through clear status diagnostics and accessible terminal layout, minimizing unplanned downtime. Bosch Rexroth Indramat’s KDA 3.1-050-3-DY0-U1 spindle drive excels in applications demanding rapid acceleration, fine dwell control, and extended duty cycles. This drive represents a balanced solution for OEMs and retrofitters seeking consistent, low-vibration spindle operation in high-stiffness machining centers and precision grinding equipment.
