29 +== **4. Specific Effect Presentation** ==
30 +
31 +In the case application, VB VFD demonstrated multiple effects.
32 +
33 +First, it has significant economic and energy-saving advantages. Through microcomputer control, the system can automatically adjust the temperature of the end air duct to achieve automated operation. The coils can be turned off even when no one is using them, further saving energy.
34 +
35 +Secondly, the application of VB high-performance VFD makes the equipment start and stop more quickly and stably, and has the advantages of large starting torque and small impact on the power grid. This provides more efficient and reliable guarantee for long-term operation.
36 +
37 +In addition, it has overload, overcurrent, overvoltage, phase loss and other protection functions, which can greatly improve the safety of the system. This enables the system to protect itself promptly and effectively in the face of various possible problems, further ensuring the stability and reliability of the system.
38 +
39 +Finally, VB’s optimized programmable DI terminal allows the VFD to easily cope with the requirements of various occasions. It also provides greater flexibility for practical applications. Users can customize settings and operations according to actual needs to meet various application scenarios.
