KDA 3.2-050-3-DYS-W1, Bosch Rexroth Indramat, KDA Spindle Drives. This spindle drive delivers a robust Rated Current of 50 A and operates on a DC Bus Voltage of 300 V for continuous, high-precision spindle control. Engineered by Indramat, it features a rigid design with integrated positioning functions and a wide speed range, ensuring stable torque under varying load conditions. The drive architecture supports seamless integration into CNC systems, while its compact frame conserves cabinet space.
Featuring a Product Series KDA 3 platform, the unit draws power for its heatsink blower from a dedicated AC Supply for Heatsink Blower of 220 VAC and employs Forced cooling via heatsink blower to maintain optimal thermal performance. Speed commands are input through a Digital 16-bit parallel interface for ultra-fine resolution, and an Aux Interface RS-232C serial interface enables remote diagnostics and parameter adjustment. An Aux Encoder Input accepts both auxiliary and synchronous feedback signals for closed-loop positioning, while the drive’s Design 2 version incorporates enhanced EMI suppression. Compact dimensions and a modular mounting scheme simplify installation and service access.
Engineers will appreciate the KDA 3.2-050-3-DYS-W1’s reliability under continuous operation, with its heatsink blower ensuring stable temperatures even at peak loads. The drive’s standardized communication channels and robust thermals lower downtime and streamline commissioning across milling, turning, and grinding applications. Designed for high-stress industrial environments, this spindle drive excels in precision machining centers where stiffness, speed accuracy, and long-term performance are critical.
