Product Description:

Designed for synchronous and asynchronous motor regulation, the 12.G6.CDB-3910 is a robust KEB inverter suited for precision motion control applications. It provides reliable torque and speed regulation, providing optimal motor performance in manufacturing, robotics and other applications. The inverter offers both analog and digital control as standard, offering versatile motor regulation options. With analog control users can make smooth, continuous adjustments, ideal for fine-tuning speed and torque. The digital control option offers high level precision in repeatable commands, enhancing automation accuracy. This flexibility makes the drive suitable for a wide range of automation processes, providing flexibility based on specific application demands.

This inverter supports a 3-phase 400V AC/DC connection, making it widely compatible with different industrial power systems. It can efficiently convert incoming 400V three-phase AC power into controlled output. It can also be integrated into DC bus systems, enabling energy-efficient operation and power-sharing between multiple drives. The drive’s 4kHz switching frequency ensures the accuracy of output voltage and current regulation, leading to reduced motor noise and lower torque ripple. This results in quieter operation, improved efficiency and better performance in dynamic applications. The inverter can support a short-time current limit of 180% which enables it to handle temporary overload conditions without affecting performance.

The 12.G6.CDB-3910 features an overcurrent cut-off threshold of 216%, ensuring robust protection against excessive current draw. This safeguard automatically shuts down the drive when the current exceeds safe limits, preventing damage to internal components and connected motors. This model is designed with an air-cooled heat sink, ensuring efficient thermal management without the need for external liquid cooling systems. This helps to effectively reduce maintenance requirements and simplifies the installation process.
