Product Description:
The KDA 3.1-050-3-A0I-W1 is a main spindle drive from Rexroth Indramat that is made for controlling spindles. The spindle drive is from Series 3 and has a flexible design that lets it fit into machine tools more easily. The drive is meant to be used in CNC centers for milling, turning, and grinding, where exact spindle control is needed.
The KDA 3.1-050-3-A0I-W1 spindle drive can handle a DC bus voltage of 300 V and has a maximum current of 50 A. The speed command link needs an analog input with a range of ±10 V to work. It stays cool with a forced-cooled heatsink blower that needs its own 220 VAC source. The product can be installed up to 1000 meters above sea level without losing any of its standard data. For normal function, the permanent ambient temperature range is +5 to +45°C, and with less data, it can go up to 55°C. The temperatures used for storage and shipping are between -30°C and +85°C. According to DIN 40 050, the level of protection is IP10. It has an incremental encoder output that lets you get high-resolution input and works with diagnostic tools and status lights. The product is made to have a small size and can be switched out within Series 3. It does not come with an extra encoder input port.
The KDA 3.1-050-3-A0I-W1 spindle drive has Design 1 according to the manufacturer's standards and meets the requirements for permanent humidity set out in DIN 40 040. The layout of the drive makes it possible to integrate it in flexible ways that meet the needs of different machines. The interface makes it easy to join and send commands, and receive feedback. It is made so that the drive part works reliably in controlled settings.
