Product Description:
The KDA 3.1-150-3-LY0-U1 is developed by Rexroth Indramat for spindle drive tasks in automated systems. It is engineered for high stiffness, ensuring minimal deflection and vibration during dynamic load changes and high-speed machining. This structural rigidity enhances the drive’s ability to maintain precise spindle positioning and rotational stability, especially under cutting forces that would otherwise introduce mechanical inaccuracies. As a result, the drive supports tighter tolerances and higher repeatability in demanding applications. It is ideal for tasks that require consistent mechanical response under varying loads, such as high-precision turning and multi-axis robotic processes.
The KDA 3.1-150-3-LY0-U1 includes built-in control and monitoring functions, which allow it to independently manage key operational parameters without relying entirely on external controllers. This integrated intelligence enables the drive to monitor internal conditions such as temperature, current, and operating status in real time. It can react autonomously to certain system conditions, such as triggering shutdowns or warnings in the event of overloads or faults. By having control and diagnostic capabilities embedded directly within the unit, the drive enhances system reliability and simplifies troubleshooting. This minimizes unplanned downtime and maintenance efforts while ensuring safer and more efficient operation.
The KDA 3.1-150-3-LY0-U1 is designed to operate with a 3 x 380–460 V AC input. This input configuration ensures the drive receives a balanced and stable electrical supply, which is essential for delivering consistent power to the spindle motor. Operating on a three-phase input also allows for greater energy efficiency and reduced electrical stress on components. This unit is designed for air cooling, a straightforward and efficient method that reduces the need for complex external cooling infrastructure. This ensures consistent performance in continuous industrial use.
