Product Description:

The Bosch Rexroth developed the KDA 2.1-100-3-LPS-W1 Spindle Drive. It is a compact and high-performance device built for industrial automation services. This spindle drive features a 100 A rated current. The heatsink blower requires a 220 VAC cooling fan supply. There is low loss of power due to an optimized internal configuration.

The KDA 2.1-100-3-LPS-W1 spindle drive utilizes a 300 V DC bus voltage for drive operations. The unit is non-sealed and has to be mounted in a cabinet. The forced air system is used to provide external cooling. A proper air flow should be provided to avoid overheating or thermal shutdown. The cooling of the drive is provided with the help of an external heatsink having a blower. The maximum altitude of installation of the drive is 1000 meters above the level of sea. It operates in a non-condensing environment with humidity up to 70%. The KDA 2.1-100-3-LPS-W1 spindle drive features modular installation for quick system integration. It has connections with compatible feed and supply units. The drive consists of a diagnostic interface through RS-232C. It also offers the input support of auxiliary encoders. This enables the accurate and concrete feedback of the motor during operation.

The KDA 2.1-100-3-LPS-W1 spindle drive is digital and uses the SERCOS interface. The spindle speed control is made in real-time and reliable due to this interface. It works and operates at a temperature from +5°C to +45°C. The spindle drive contributes to the high positioning capabilities as the spindle reaches high speeds. All electrical connections follow standard interfaces for simplified setup. Shielded cables and grounding are required for EMC compliance. This spindle drive has a design that enables it to last longer in controlled conditions.
