Product Description:
The KDA 3.1-100-3-D0I-U1 by Bosch Rexroth Indramat is a main spindle drive designed for machining tasks that require excellent positioning control. Its built-in minicomputer allows for autonomous drive control, delivering smooth speed regulation and monitoring without needing external processing. The drive has a strong construction that minimizes deflection under different load conditions. This helps keep positioning accuracy consistent during tough machining cycles. The drive also features unique positioning capabilities that use advanced algorithms to ensure reliable performance.
This spindle drive offers impressive speed control precision, reaching as low as 0.0005 rpm. This enables extremely precise tasks like thread cutting, gear hobbing, and fine boring. The drive can handle a nominal current of 100 A, providing strong torque for heavy-duty applications. It is built to perform smoothly even at very slow speeds, making it versatile for various spindle tasks. The drive’s digital 16-bit parallel speed command interface provides accurate speed reference input with high resolution and increases efficiency by removing quantization errors. The drive supports 300V DC input, which optimizes power delivery and ensures compatibility with standard industrial power systems.
The KDA 3.1-100-3-D0I-U1 features an auxiliary interface designed to provide incremental encoder output functionality. This allows for real-time feedback to external monitoring systems and secondary control loops. The interface makes it easy to connect with machine tool controllers and quality monitoring devices that need direct spindle position data. The drive's built-in intelligence consistently checks operational parameters, offering diagnostic features that improve system reliability and lower maintenance needs. The combination of precise control and thorough monitoring makes this drive especially suitable for precision grinding tasks.
