It contains 14 power frequencies, which integrates the main drive of the underground belt conveyor, the cooling water tank, the braking device, the tensioning device, the tape reel device and other load drives, reducing the floor space and improving the degree of centralized control of the equipment;
Based on high-power IGBT and high-performance vector control technology, the three-level topology is adopted, and the inverter trigger signal is isolated by optical fiber, which has higher efficiency and reliability;
The HMI configuration screen adopts a humanized and parametric design, and displays the relevant parameters such as the start and stop status, voltage, current, motor temperature, fault information and historical record query of the belt conveyor in real time;
It has a variety of communication modes such as Ethernet and RS485, which is convenient to access the mine information system and realize remote control and automatic control.
