International electrical safety standards: The requirements are in line with international electrical safety standards, such as CE standards in Europe and UL specifications in United States. These specifications specify the requirements for electrical safety functions, mechanical safety functions, EMC functions, etc. ...

There are two types of inverter parking. One form is called "free parking". As the name suggests, it is to quickly "power off" the motor, so that the motor can slide and park by its own inertial force (OFF2 parking); The other form is called "brake parking". So this "brake parking ...

The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the capacitor voltage being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and avoid energy waste. However, the capacitance of the capacitor is ...

Most inverter brand products can rely on the heat generation of internal electrical components to remove moisture during normal use. If you don't have to do it for a long time, it's easy to get wet. The chip pins, penetrating resistors, capacitors, and inductor pins of the DIP package will be severely rusted or desoldered, resulting in on-resistance ...

1. The switching signal of PLC controls the inverter The PLC can control the start, stop and reset of the inverter through the program; It can also control different combinations of high-speed, medium-speed and low-speed terminals of the inverter to achieve multi-stage speed operation. However, because it is controlled by switching ...

Among them, QS1 is a single-pole single-throw variable frequency incoming knife switch, and QS2 is a single-pole double-throw power frequency and variable frequency outgoing knife switch. The bypass cabinet is a high-voltage environment, please investigate the status of the live display and electromagnetic lock to ensure safety before ...

1. The inverter can not speed up the frequency increase when it starts with load The 1366S-BR 040 inverter carries a load of 37 kW fan motors. During the trial operation, it was found that the inverter could not speed up the frequency increase normally, and the HIM display was speeding up. The inverter only swings at 1-4 Hz, and the motor emits a buzzing ...

1. Appropriate working environment 1. The ambient temperature is suitable All manufacturers have certain rules for active temperature control cabinets. The PLC promises that the ambient temperature is usually about 0 to 55 ° C, so during the equipment process, this heating element is not placed in the PLC; The PLC should have adequate ventilation and ...

In the repair of the inverter, we often hear about overpressure problems, but underpressure problems are also common problems encountered in the use of inverters. The reason is that the main circuit voltage is lower than the lower limit caused by the maintenance action or the damage of a rectifier bridge or the instantaneous power failure of the power grid, and the input is flat. Inverter after-sales ...

Bypass cabinet: The cabinet is equipped with high-voltage inlet and outlet isolation switches QS1 and QS2, as shown in Figure 2. Among them, QS1 is a single-pole single-throw variable frequency incoming knife switch, and QS2 is a single-pole double-throw power frequency and variable frequency outgoing knife switch. The bypass cabinet is a high-voltage environment, please observe the live display and electromagnetic lock status to ensure that the ...

The state proposes to "peak carbon emissions" by 2030 and complete "carbon neutrality" by 2060. Carbon neutrality is to try to reduce carbon dioxide emissions, and eventually achieve net zero emissions, that is, to make carbon dioxide emissions even offset. However, due to economic development, CO2 emissions are stable ...

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 ...

Soft starters and frequency converters are two completely different products. The inverter is used in the local area where speed regulation is required, and its output not only changes the voltage but also changes the frequency at the same time; A soft starter is actually a voltage regulator, which is used when starting a motor, and the output only changes the voltage and does not change the frequency. Change...

When it comes to inverter repair, it's not enough to understand the above fundamental circuits, but also to understand the following primary circuits. The main circuit is mainly composed of rectifier circuit, current limiting circuit, filter circuit, braking circuit, inverter circuit and detection and sampling circuit. ...

Special inverter suppliers remind you that in daily industrial production, there are inverters that do not require rectifier units, which are the so-called alternating current inverters. However, the vast majority of the market is AC-DC-AC frequency converter, which also contains a rectifier unit, which is a certain level of technology and market competition.

1. EPS the first use of the emergency power supply, the battery pack should be charged continuously for 48 hours after discharging protection; 2. EPS emergency power supply to keep the whole machine dry, clean, free of dust and foreign objects, wipe with a soft cloth after shutting down, and strictly ...

After selecting the resistance value of the braking resistor, the power value of the braking resistor should be confirmed, and the selection of the braking resistor power is relatively cumbersome, and it is related to many factors. The instantaneous power consumed by the braking resistor is calculated according to the following formula: P instantaneous = ...
