Product Description:
The KDA 2.1-050-3-AQ0-W1 belongs to the well-known brand Bosch Rexroth Indramat’s top-reviewed KDA Spindle Drives lineup. Featuring a 50/60 Hz supply frequency, the unit supports global grid standards and streamlines configuration steps. Availability of panel mount installation securely locks the module into standard control cabinets, maximizing rack density. A communication interface using analog command processes direct speed inputs, simplifying integration with analog control systems. Resolver or encoder feedback options provide well-defined position sensing to improve spindle synchronization.
An IP20 protection class effectively blocks solid intrusions larger than 12 mm, safeguarding sensitive electronics. Plug‑and‑play readiness enabled through compatibility with Indramat MAC series motors, minimizing parameter setup. Ambient temperature tolerances from 0°C to 45°C to match worksite conditions, eliminating the need for additional enclosure climate control. This continuous torque delivery under heavy loads ensured by a 50 A rated output current and maintains machine consistency. By concentrating control on one spindle, the single‑axis capability reduces drive count for dedicated applications. The motor uses internal blowers that circulates room air through air cooling and reduces heat flow without requiring external coolant systems.
Input voltage system at 3 × 220–230 VAC of KDA 2.1-050-3-AQ0-W1 module aligns with European and North American three‑phase supplies which cuts electrical requirements. Bus voltage 300 VDC supports the intermediate link by minimizing current fluctuations and maintaining voltage consistency. Powered at 220 VAC, the heatsink blower actively forces airflow to regulate temperature and avoid thermal overloads. The ±10 V analog speed command input swiftly interprets external signals, optimizing real-time speed adjustments. Moreover, the drive’s auxiliary encoder input, designed for 1 V sinusoidal signals, gathers precise high-resolution feedback for refined control. With a high mechanical stiffness design, it reduces torsional deflection and enhances positioning precision. An extensive speed range up to 12,000 RPM accommodates diverse spindle applications which expand machining versatility.
