Technical Advantages And Characteristics
All the regulation and control of the product are fully digitalized, the influence of component aging and temperature drift is small, the anti-interference is good, it is reliable and can keep the accuracy for long time.
This product is highly scalable and can be realized by adding optional parts tomeet the special requirements of different customers for the number of interfaces and interface functions.
This product has super-strong function of fault self-diagnosis and treatment. It can monitor and deal with all kinds of faults such as phase loss, over current, over voltage, under-excitation, over speed, etc. It can simulate the temperature rise curve of the motor and monitor the overheating of it.
This product has strong communication capability, which supports many communication protocols, such as DCS LINK、PROFIBUS、CAN, etc. It can communicate with the up one level automation system through communication interface or adding optional board to realize the production process automation conveniently.
This product has the advantages of convenient operation and simple debugging. The dynamic parameters of the control system can be debugged by the operation panel or the upper computer debugging software, and the program optimization is completed automatically.
Advantage of main circuit selection
The armature main circuit of the product adopts the scheme of two three-phase full-control bridge reverse parallel no circulation,which can run by four quadrants and realize the two-way flow of energy. It has the advantages of high voltage and high current in power element selection, and can start with high torque, and ensure continuous operation with full torque at low speed.
Advantages & characteristics of structural
This product is designed according the structure of DC speed regulating device, and can upgrade and replace the DCS device on-site. With the advantages of compact and reasonable structure, it can easily, quickly and simply replace the components to significantly improve the operability of on-site technical maintenance.
