KDA 2.1-150-3-AYD-W1

The Bosch Rexroth Indramat KDA 2.1-150-3-AYD-W1 from the KDA Spindle Drives series is engineered for high-performance spindle control in demanding industrial applications. This main spindle drive delivers a Rated Current of 150 A and operates on a DC Bus Voltage of 300 V to provide continuous power across extensive speed ranges. It offers an Analog ±10 V Speed Command Input for precise speed regulation and employs Forced air via heatsink blower cooling to ensure reliable thermal management under heavy load.

Delving into its technical specifications, the drive features a 16-bit parallel digital position command auxiliary interface for accurate motion control and integrates an encoder input supporting both auxiliary and synchronous modes to facilitate advanced feedback. The blower is powered by 220 VAC, ensuring consistent airflow through the heatsink blower cooling system. The KDA 2.1 design version is optimized for rigidity and positioning accuracy, making it ideal for precision spindle applications.

Additional features underscore the drive’s compatibility and efficiency: its Analog ±10 V Speed Command Input and robust encoder interface seamlessly integrate with various CNC and automation platforms. The forced-air heatsink blower enhances durability by maintaining stable operating temperatures, which reduces thermal stress and extends component life. With its high rated current and substantial DC bus capacity, this drive supports extended duty cycles without performance degradation. The KDA 2.1-150-3-AYD-W1 excels in industrial settings by delivering precise speed control, reliable cooling, and long-term operational efficiency, thereby improving throughput and reducing maintenance downtime.
