In order to avoid the interference of the control signal line between the PLC and the inverter by the space electromagnetic field, the shielding wire can be connected to the outer layer of these control signal lines to improve the anti-interference ability of the system. This kind of wiring must be noted, and only one point can be selected for the grounding point of the shield. Whether it's on the PLC side, or ...

Now many electrical appliances are advocating the use of small parts, because small parts will not occupy space, and small parts can be moved and overhauled at any time, and the inverter also has a small inverter, how to buy a small fan inverter? Power picking ...

1. The wires laid out in the inverter control circuit should be separated from the main circuit cable (power line), so as to avoid the harmonic disturbance components on the side of the main circuit of the inverter from polluting the inverter control circuit; 2. Due to the faulty signal of the inverter and ...

The first way to use the inverter is to change the output frequency to achieve the controllability of the motor speed, so do you know what steps to complete the output frequency controllability? One of the first and foremost key points is how to complete the change of the frequency signal supplied by the inverter equipment.

1. Safety precautions 1. The primary requirement is to have certain electrical professional knowledge, and understand the job site, understand the equipment status, and have certain electrical operation technology. 2. Determine the electrical ...

According to the requirements of the operating conditions, the appropriate load inertia accounting formula is selected to calculate the load inertia of the organization. According to the load inertia and servo motor inertia, the appropriate servo motor standard is selected. Combined with the inertia and load inertia of the primary servo motor, the acceleration torque and deceleration are calculated.

We need to ensure that the capacity of the inverter is matched. First of all, according to the nature of the load, the correct selection of the type of inverter. When selecting the inverter, the current value of the actual motor should be used as the basis for the selection of the inverter, and the rated power of the motor can only be used as a ...

Low pressure issues The VFD reports a low voltage glitch when the drive's DC link voltage drops below 62% of the nominal level at the high setting (480 Vac) and 50% of the nominal value at the low setting (400 Vac). The +10% and -15% voltage tolerances in most manuals are the ones that claim to be ...

1. Overpressure leads to brake pipe breakdown. The so-called overvoltage of the inverter refers to the fact that the inverter voltage composed of various reasons exceeds the additional voltage, which is reflected in the DC voltage of the inverter DC bus. Overvoltage alarm generally appears when the machine is shut down, and its main ...

Rectifier circuit: rectify 50HZ communication power into direct current. Frequency conversion circuit: The rectified direct current is inverted into a variable frequency communication current. Control part: control the frequency of communication electricity output by the inverter circuit. Maintenance circuit: maintenance and blockage of overcurrent and phase loss ...

1. In order to save power, the inverter is selected Many manufacturers and salesmen praise how high the power-saving rate of the inverter is, and the user also believes that it is true, and the inverter is selected at a high cost simply in order to save electricity, but the results are greatly disappointed. Whether the inverter can save power after using it is determined by the load driven by it.

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This effectively prevents the inverter's control circuit from being disturbed by harmonics in the inverter's main circuit. 2. To separate the connection of the inverter from the terminals or contacts of other control circuits, ...

Misunderstanding: connect electromagnetic switches and electromagnetic contactors in the output circuit of the inverter In actual use, some occasions require the use of contactors for frequency converter switching: such as when the frequency conversion is faulty, switch to the power frequency operation, or when the one-to-two method is adopted, a motor is faulty, and the variable frequency is used.

General treatment methods for inverter overcurrent problems: The output side of the inverter is a PWM voltage waveform, and after passing through the motor winding, the output current is approximately a sine wave, and lags behind the voltage by a phase viewpoint, which is determined by the power factor of the motor. The output current of the inverter passes through ...
