1. Leakage protection switch Phenomenon: The leakage protection switch of the equipment is activated when the inverter is powered on or running Measures: When the inverter drives the motor, the leakage value is larger than that of the non-inverter system, and the leakage protection value of the leakage protection switch is required to be 150mA and above, and the action delay is ...

1. It is necessary to figure out the basic parameters and shape of the device that needs to be replaced. The basic parameters include the rated operating current, the capacitance of the capacitor, the resistance value of the resistor, the value of the GTR Darlington device (current amplification factor), the switching characteristics of the IGBT (including IPM) device, and the saturation voltage ...

1. The operating ambient temperature of the inverter (mainly refers to the air temperature of the air inlet of the power unit cabinet) requires a minimum ambient temperature of -5 °C and a maximum ambient temperature of 40 °C. In order to improve the reliability and extend the service life of the drive, check the following items: Air conditioning and refrigeration ...

External electromagnetic interference can easily cause malfunctions If there are interference sources around the inverter, they will invade the inside of the inverter through radiation or power lines, causing the control loop to malfunction, causing abnormal operation or shutdown, and even damage to the inverter in severe cases. Noise suppression on the outside ...

1. Maintenance items and scope: Daily maintenance and maintenance of inverter Due to the influence of environmental temperature, humidity, dust and vibration, it will lead to the aging of the internal components of the inverter, resulting in the potential failure of the inverter or reducing the service life of the inverter. Therefore, there is a must ...

First, the process requirements When the low-pressure pressure collected by the system is greater than the upper low-pressure pressure set by the touch screen, the compression time will be loaded according to the set loading time, and the lower pressure will be reduced according to the set load reduction time. The high pressure collected is greater than that on the high pressure ...

1. E1: indicates sensor failure. In this case, it is necessary to check whether the sensors of Megmeet are damaged or whether the wiring is loose. 2. E2: Indicates overweight load. At this point, it is necessary to check whether the load of Megmeet exceeds the set maximum load. 3. E3: Indicates battery ...

1. Metallurgical industry - the application of high-voltage inverter in the metallurgical profession mainly includes plate and wire rod rolling mills, coilers, fans, slurry pumps, etc., with the primary intention of motor energy saving. 2. Electric power industry - China's power generation capacity ranks second in the world, second only to United States. The power profession is also changing.

1. Unified setting of Megmeet welding machine The so-called unification of welding means that the welding machine automatically matches the welding voltage according to the currently set welding current and the unification voltage correction value. The unification setting of Megmeet welder should first turn on the function on the welder side, ...

1. When the oscilloscope looks at the current monitoring output of the driver, it finds that it is all noisy and cannot be read Cause: The current monitoring output is not blocked from the AC power supply (transformer). Solution: You can use a DC voltmeter to detect and investigate. 2. Servo motor high speed ...

The butt welding machine should be settled indoors, and should have a reliable grounding or zero connection, when a plurality of butt welding machines are connected to each other, the distance from each other shall not be less than 3m, and they should be connected to different corresponding power grids, and should have their own knife switches. Before welding, the pressure of the butt welder should be checked and determined.

1. CPU abnormality: When the CPU is abnormally alarmed, check the device connected to the internal line of the CPU unit. The specific method is to replace the units that may cause failures in turn, find out the faulty units, and deal with them accordingly. 2. Memory abnormality: When the memory is abnormal alarm, if it is a program ...

1. Input processing Input processing is also called input sampling. In this phase, the through-end state of all input terminals is read sequentially, and the read information is stored in the corresponding image register in memory.
