KDA 3.1-050-3-DYD-U1
KDA Spindle Drives
KDA 3.1-050-3-DYD-U1, Bosch Rexroth Indramat, KDA Spindle Drives presents a precision spindle drive with a compact panel mount form factor and robust IP20 protection class. This unit accepts a 3-phase, 380...460 V AC input at 50/60 Hz and delivers a continuous output current of 50 A, peaking at 75 A for dynamic load responses. Its digital control architecture features a 16-Bit parallel speed command value and a standard communication interface for seamless integration. Resolver feedback ensures precise position sensing under harsh industrial conditions.
Leveraging a 300 V DC bus voltage, the drive maintains thermal stability via a forced-air cooling method supported by a dedicated 115 V AC heatsink blower supply. Integrated fault diagnostics, powered by a microcomputer-based system, continuously monitors performance and displays errors in real time to minimize downtime. The unit supports up to three axes and offers an ultra-fine speed control range from 0.0005 rpm to maximum, ideal for high-precision C-axis operations. Digital control and resolver feedback converge to deliver smooth torque and accurate motion profiles.
Engineered for industrial automation, the KDA 3.1-050-3-DYD-U1 excels in CNC machinery, robotics, and multi-axis motion platforms. Its combination of reliable resolver feedback, high overload headroom, and on-board diagnostics simplifies commissioning and maintenance. Panel-mount installation and standard control interfaces streamline system integration, while the drive's rugged design ensures long-term reliability in demanding production environments.
