Product Description:

The Rexroth Indramat KDA 3.2-050-3-AYS-W1 Main Spindle Drive is an industrial grade drive designed for precision spindle control in automated systems. It offers reliable operation under a wide range of temperatures and is built to support consistent performance in continuous duty applications.

This KDA 3.2-050-3-AYS-W1 main spindle drive supports a continuous current rating of 35 A that is suitable for applications that demand stable and sustained current supply. It is equipped with a forced cooling mechanism through a heatsink blower which ensures consistent thermal regulation during high-load operation. The blower unit (LE4) has a total weight of 4.2 kg. The unit operates efficiently within a nominal ambient temperature range of + 5 to + 45 °C. It consumes a 24 V load voltage with a current draw of 1.2 A which supports its auxiliary systems and blower function. The drive includes both auxiliary and synchronous encoder inputs to enhance position and speed feedback accuracy. These encoder interfaces ensure compatibility with various control architectures and provide stable signal processing. The drive system is designed with input flexibility to accommodate different encoder types based on the required configuration.

The KDA 3.2-050-3-AYS-W1 main spindle drive meets environmental standards with permissible humidity rated as category F. This rating confirms the drive’s resilience in environments with standard industrial humidity levels. Its compact form and light weight including the 1.7 kg mounting kit simplifies handling during installation and maintenance. The drive's mechanical and electrical interfaces are designed for secure and reliable operation. All input and output ports are arranged for ease of access during setup. The ±10 V analog speed input provides compatibility with conventional control systems and ensures stable motor performance across varying load conditions.
