Product Description:

The KDA 3.2-050-3-LQI-U1 is an intelligent digital control drive suited for spindle drive applications. It offers compatibility with asynchronous motors and frameless spindle motors, allowing for smooth coordination within sophisticated motion control systems. The motor functions by processing real-time feedback and implementing control algorithms that adjust to load variations, speed changes, and positioning demands. This digital control architecture allows for precise regulation of motor behavior, ensuring its performance aligns with application demands. This drive is liquid cooled, allowing heat produced during operation to be dissipated efficiently.

The KDA 3.2-050-3-LQI-U1 has a 50 A output current rating, indicating the highest continuous current the drive can provide to the attached motor. This enhanced current handling ability makes the drive efficient in demanding spindle drive applications where quick acceleration, deceleration, and steady load handling are essential. It can effectively support heavy-duty motors with significant torque output. This drive supports three-phase industrial power systems and operates with an AC input voltage of 400/460 V. This range means that the drive can be installed anywhere in the world due to its compatibility with common North American (460 V) and European (400 V) supply grids. Its support for higher voltage levels also increases overall energy efficiency by lowering the current needed to deliver a given amount of power.

The KDA 3.2-050-3-LQI-U1 offers a variety of communication and control options to accommodate various automation environments. It supports SERCOS, Analog, and Digital I/O interfaces. The SERCOS interface allows for synchronized and fast communication with motion controllers. For speed or torque control commands from external devices or legacy systems, the drive can receive and process continuous voltage or current signals thanks to analog interfaces. The digital I/O channels provide discrete signal handling, ensuring efficient system performance.
