Definition of the two Frequency converter is a power control device that converts the power frequency power supply into another frequency by the on-off action

1. When the motor current in the inverter is set too large, the motor protection parameter is set too large, and the inverter cannot protect

1. The main circuit is the power conversion part that provides voltage regulation and frequency regulation power supply for the asynchronous motor. The main circuit

Inverter and frequency conversion principle of inverter The process by which a frequency converter converts direct current to alternating current is called “inverting”. Let’s talk

The carrier frequency of the inverter is to modulate a lower signal frequency to a relatively higher frequency. The higher frequency modulated by the low

2.2KW inverter reports fault EFAL The fault description is that the output current is too large, the DC terminal voltage is too high, the internal

Today in the 21st century, the global energy shortage, the voice of energy conservation is getting louder and louder, and advanced energy conservation technology has

The mining design of modern coal mine working face gradually develops in the direction of working face direction, large inclination length, high mining height and

1: PRG, function: enter the parameter setting interface, and switch between different series of parameters. 2: ENTER. Parameter confirmation. After we adjust the value of
