Product Description:

The KDA 3.1-100-3-D0S-U1 is a spindle drive in the high-precision KDA drive series by Rexroth Indramat. It features RS-232C serial communication that allows for integration with older control systems and diagnostic tools. The RS-232C interface offers dependable point-to-point communication for setting parameters, monitoring, and troubleshooting in situations where network communication is unnecessary. This capability enables the drive to work with older CNC systems and specific test equipment that use standard serial protocols. The drive has an integral microcomputer that handles all communication tasks while keeping main spindle control functions active without losing performance.

This spindle drive uses a strong construction that reduces mechanical bending under different load conditions. This design ensures consistent performance throughout its operational range. With a 100 A current rating, the drive delivers solid motor drive power for tough machining tasks. Its wide speed range supports both high-speed cutting and precise low-speed positioning tasks. The integrated control system is designed to optimize operation by continuously checking key settings like current, temperature and speed. This enables detailed diagnostic information through the serial interface for swift resolution of potential issues. The control system of the drive is automated to boost motor performance and support predictive maintenance, enhancing overall ease of use.

The KDA 3.1-100-3-D0S-U1 drive uses a forced cooling mechanism for managing heat generated during operation. This allows the drive to adapt easily to dynamic load conditions as well as long duty cycles without risk of overload damage. This unit supports 3-phase 400 V AC input, enabling seamless integration into a wide range of system designs. The drive is constructed for durability and is well-suited for panel mounting in control enclosures. Its ingress protection level meets IP20 guidelines indicating the need to prevent exposure to moist or dusty conditions for optimal reliability.
