There is a circuit breaker QF and a communication contactor KM between the power supply and the inverter, when the inverter does not need to be used for a long time. or when the equipment is overhauled, the circuit breaker is used as an isolation switch, which can block the power supply and ensure the safety of maintenance. It has maintenance functions such as overcurrent and undervoltage. The main power of the inverter ...

There are three connection control methods between PLC and inverter: 1. Use the analog output module of PLC to control the analog output module of the inverter The analog output module of the PLC outputs 0-5V voltage signal or 4-20mA current signal, which is used as the analog of the inverter.

Soft starter is actually a motor control device with motor soft start, soft stop, light load energy saving and a variety of maintenance functions. First of all, it is a three-opposite parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. By manipulating the conduction of three opposite parallel thyristors ...

1. The motor slows down too slowly 1) If the deceleration time is set too long, reduce the deceleration time 2) Install a braking resistor 3) Add DC braking 2. The motor is overheated 1) The load is too large, and the practical moment has exceeded the ...

Investigation of the function of the inverter system Before debugging the frequency converter, it is necessary to carefully read the operation instructions and related information of the inverter to be debugged to understand the application environment and precautions. Especially before the inverter is energized, it is necessary to carefully observe and see if the inverter has obvious problems.

First, the operation of the machine before the technical transformation The sugar separation process of a sugar factory in Yunnan uses centrifugal dehydration method. The separation machine is mainly composed of a cone drum and a drive motor, and the motor shaft is directly connected to the bowl. Solid sugar crystallized from a high concentration of sugar water, in a cone bowl ...

Dry-type transformer is a kind of power equipment, and under normal circumstances, dry-type transformer also requires a certain amount of overload, that is, the workload beyond its working ability. So what about the overload of dry-type transformers and how to influence them? ...

The difference between a voltage converter and a current converter Voltage inverter and current inverter are two different operating principles, for example, the operating principle of voltage inverter is mainly to regulate the voltage source, and the voltage source regulates the current to achieve the effect of conditioning, while the current inverter is a direct ...

In some fields, the use of inverter to control the motor will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. According to the inverter control motor ...

There are two ways to park a drive. One way is called "free parking". It is to quickly "power off" the motor, so that the motor can slide and park by its own inertia force (OFF2 parking); The other way is called "braking parking". So this "brake parking ...

From September 15th to 19th, the 22nd China International Industry Fair was held at the National Convention and Exhibition Center (Shanghai). As the first national industrial exhibition held under the normalization of epidemic prevention and control this year, the theme of this expo is "Intelligence, Interconnection: Enabling the New Development of Industries".

In order to thoroughly implement the spirit of General Secretary Xi Jinping's important instructions that the economic power must be a maritime power, a shipping power, economic development, a strong country, and transportation, especially shipping, and the implementation of the outline for the construction of a transportation power, the port ship shore power system has become the standard for green ports.

It is hoped that Sunland inverter is mainly used in three-phase asynchronous AC motor to control and adjust the motor speed. Sunland inverter is mainly composed of microprocessor, including rectification, filtering, inverter, brake, drive, detection, etc. In order to achieve the purpose of changing the power supply voltage, according to the actual needs of the motor...

Hope Sunland inverter part of the fault code Er.ocb (1) Overcurrent at the moment of starting: There is a short circuit inside the motor There is a short circuit in the motor wiring The starting voltage is too high Check the motor and wiring Check the motor wiring Seek service Check the torque ...

1. Incoming line maintenance Incoming maintenance is the maintenance of the user's inlet end and inverter, including lightning protection maintenance, grounding maintenance, phase loss maintenance, inverted phase maintenance, unbalance maintenance, overvoltage maintenance, transformer maintenance and so on.
