Model and Parameter

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 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, demagnetization, overs peed and so on. 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 SINAMICS LINK、PROFIBUS、CAN、USS and so on. It can communicate with the up one level automation system through communication interface or adding optional board to realize the automation of production conveniently.

The 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.

Selection advantage of main circuit

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.

Structural advantages and characteristics

This product is designed according the structure of 6RA DC speed regulating device, and can upgrade and replace the 6RA device in the field. With the advantages of compact and reasonable structure, it can easily, quickly and simply replace the components to significantly improve the operability of field technical maintenance.

Advanced control methods

This product adopts the scheme of double closed loop control of speed and current, that is, the double closed loop speed control system is with current loop as the inner loop, the speed loop as the external loop, it is speed control scheme without logic circulation. All digital control and regulation system, different customer requirements, types and number of interfaces, as well as calculation performance and speed, can be accurately implemented through standard CUD, with the advantages of good dynamic performance, rugged and durable, high cost performance.
