KDA 3.2-050-3-DQI-U1

The Bosch Rexroth Indramat KDA 3.2-050-3-DQI-U1 from the KDA Spindle Drives series delivers robust performance as a main spindle drive with a Rated Current of 50 A and a DC Bus Voltage of 300 V. Designed under the Design 2 specification and part of the Product KDA family, it employs a Digital 16-Bit Parallel Speed Command Value for high-precision control. Integration is simplified through an Aux. Interface of Incremental Encoder Output and a dedicated Aux. Encoder Input for 1V Sinusoidal Enc.. The drive’s AC Supply Source for Heatsink Blower of 115 VAC ensures reliable cooling under demanding production conditions.

Reliability is enhanced by Forced Cooled by Heatsink Blower architecture that maintains stable operating temperatures even at high continuous loads. The drive’s compact footprint and modular build benefit from the standard Series 3 configuration, making it compatible with existing machine bases and retrofits. Advanced positioning features take advantage of the parallel speed command bus to achieve fine speed resolution and rapid response. Industrial-grade components and meticulous Bosch Rexroth Indramat quality controls guarantee long service life and repeatable performance.

Optimized for high stiffness and a wide speed range with continuous power delivery, the KDA 3.2-050-3-DQI-U1 is well suited for precision milling, drilling, and grinding applications. Its combination of 50 A rated current, 300 V DC bus voltage, and digital command architecture ensures both power density and control finesse. This spindle drive represents a balanced solution for modern automated machining centers seeking reliability and exacting speed regulation.
