Product Description:

The KDA 2.1-100-3-DPS-U1 is a main spindle drive made by Bosch Indramat. It is designed for detailed handling in industrial automation settings. This drive is from the KDA line and is made to offer constant power, high stiffness, and precise positioning. It is controlled by a digital microprocessor, which lets the motor give high-resolution feedback for complex spindle actions.

Asynchronous 2AD motors and frameless 1MB spindle motors can be used with KDA 2.1-100-3-DPS-U1 spindle drive. The spindle drive has an estimated current of 100 A, which means it will work reliably. The 300 V DC bus voltage makes performance stable. The heatsink fan, which runs on 115 VAC 50–60 Hz, moves air through the cooling system. The drive is made with an IP10 protection class, which, according to DIN 40 050, protects against large solid items. It can be stored and moved at temperatures between -30°C and +85°C, but it can only be used at temperatures between 0°C and +45°C. The speed order value is a 16-bit digital parallel input that ensures the data is sent correctly. The speed can be changed from 0.0005 rpm to the top speed that lets the high-resolution C-axis work with a precision of ≤1/360,000 revolution.

The < has a humidity rating according to DIN 40 040 Class F, which means it will work well in places where the average relative humidity does not go above 70%. For spindle or second motor feedback, there is an extra encoder input that gives you more options. Serial transmission is built into the system through an RS-232C interface. It's building in the series is set by the design type 1, which is 1. The spindle drive can be added to advanced control systems in places where automation is used.
