KDA 3.1-050-3-A0I-W1

The Bosch Rexroth Indramat KDA 3.1-050-3-A0I-W1 from the KDA Spindle Drives series delivers precision spindle control with robust design features. Manufactured by Bosch Rexroth Indramat, this KDA 3.1-050-3-A0I-W1 drive is a Design 1 product tailored for high-performance CNC and machining applications. It provides a Rated Current of 50 A fed by a DC Bus Voltage of 300 V, ensuring continuous power delivery and stable torque across a wide speed range. The integrated Speed Command Value Analog +/- 10V interface enables smooth analog speed setpoint adjustments for dynamic spindle acceleration and deceleration.

Engineered for optimal thermal management, the drive employs Forced Cooled by Heatsink Blower cooling, powered from a dedicated AC Supply Source for Heatsink Blower 220 VAC to maintain component temperatures under heavy loads. Connectivity options include an Aux. Interface Incremental Encoder Output for high-resolution feedback and an Aux. Encoder Input Without additional encoder port to simplify system wiring when external feedback is not required. The drive’s compact footprint and modular product layout facilitate cabinet-level integration, while the Product KDA architecture supports rapid interchangeability within the Series 3 family.

This spindle drive’s combination of high stiffness, precise positioning functions, and an extensive speed range makes it ideal for main spindle applications in milling, turning, and grinding centers. Its rugged construction and consistent performance ensure reliable operation under demanding manufacturing conditions. With clear status indicators and diagnostic capabilities, the KDA 3.1-050-3-A0I-W1 minimizes downtime and streamlines maintenance processes.
