Product Description:
Bosch manufactures the KDA 3.1-050-3-DYD-W1 drive for industrial motion systems. It provides consistent operation across controlled electrical environments. Efficiency is achieved through digital regulation and structured interface design. The drive supports accurate automation functions with long-term stability.
The KDA 3.1-050-3-DYD-W1 spindle drive has a storage and transport temperature which ranges from –30 to +85 °C. Such a wide range protects the integrity of drive during shipment and warehouse handling. Installation elevation without reduction of nominal data is limited to 1000 m above sea level. That restriction ensures consistent cooling performance and prevents derating in moderate altitude applications. Protection category is IP 10 per DIN 40 050. This means the drive is only suitable for use indoors in clean areas, where dust and liquids are kept under control. Rated current is 50 A. It means the drive can handle continuous use under load without the voltage dropping too low, even during long spindle operation. DC bus voltage is 300 V. It ensures smooth power conversion and precise control of torque generation in regulated environments. The drive applies digital control architecture. Digital regulation improves response accuracy in speed and torque loops.
The KDA 3.1-050-3-DYD-W1 drive has 16-bit signal resolution signal resolution. High resolution enhances fine-step control and ensures accurate interpretation of command values. The specified signal interface is parallel. Parallel structure provides rapid transfer of data with minimal delay during high-frequency operations. The stiffness of the drive is high so that the drive responds accurately to loads. The auxiliary interface uses a 16-bit digital parallel input for position commands to enable smooth synchronization with external controllers. Integration of resolution, interface, and stiffness parameters allows the drive to deliver repeatable performance where accuracy and controlled motion are required.
