Product Description:

The KDA 2.1-100-3-A0I-U1 is a main spindle drive designed for use in a variety of applications, such as robotics, automated production lines, CNC machine tools, and textile machinery. It is made by Rexroth Indramat.

A rated current of 100 A and a DC bus voltage of 300 V are features of the KDA 2.1-100-3-A0I-U1 main spindle drive. The analog signal with a range of +/- 10V is the format that the drive accepts for speed command values. The drive is cooled using a forced cooling system that makes use of a heatsink blower. It supports INDRAMAT's 2AD asynchronous motors and 1MB frameless spindle motors, thus it is compatible with a lot of different kinds of motors. The maximum temperature that the drive can withstand is 55 degrees Celsius, but it can still work in situations as cold as 5 to 45 degrees Celsius. In accordance with IP 10 standards, the drive is shielded from particles bigger than 50 mm. In accordance with DIN 40 050, it is further protected from dirt and foreign particles by being stored in a sealed container. Up to a height of 1000 meters, it functions efficiently.

The KDA 2.1-100-3-A0I-U1 main spindle drive provides high-resolution motor or spindle feedback, which is crucial for precise position control. Its category of protection guarantees dependability in environments where external elements are restricted. The drive is also designed to handle specific motor types and features an accurate and reliable speed command value input technique. The KDA 2.1 drive integrates smoothly with automated systems that require accuracy and control to operate efficiently. The main spindle drive enclosed enclosure makes it suitable for deployment in a wide range of production situations.
