The Variable-Frequency Drive (VFD) controls the speed and operation of the motor by adjusting the frequency and amplitude of the output voltage. Specifically, the VFD controls the speed of the motor mainly through the following steps: Collecting Input Signals: VFD First ...

Switch Mode Power Supply (SMPS) will cause the base of the switch tube to fail to get the switching pulse and intermittent operation due to the short circuit of the load, the failure of the vibration circuit itself and the loss of control of the protection circuit, which makes it difficult to locate the shortcomings of SMPS. Difficult to repair ...

1. The speed regulation power is high, which is an efficient speed regulation method. This is because after the frequency change, the motor is still working in close proximity to the synchronous speed, and the rated slip is fundamentally adhered to. It's just that in the frequency conversion equipment system, there will be conversion loss, and because of the influence of higher harmonics, the loss of the motor will increase.

What is a frequency converter? Variable frequency drive (VFD) uses inverter technology and microelectronics to change the operating power frequency of the motor to control the power control unit of the communication motor. The inverter is mainly composed of rectifier (from communication to DC), inverter, inverter (from DC ...

Xinjie touch screen is an extraordinary technology product developed by Xinjie Technology Company. It not only uses touchscreen skills, but also integrates cutting-edge skills in many fields such as human-computer interaction, visual arts, and information processing, bringing skills to users. ...

1. Why can't the PLC communicate with the peripherals? Communication failures are generally summarized as the following problems: 1. Communication cable: The connection may be incorrect, or the contact is poor, the user can change the communication cable and try again. 2. Communication parameters: PLC communication port and peripheral equipment ...

Why does the motor driven by the inverter overheat? This is due to the fact that the voltage of the inverter drive motor contains a rich high-frequency component. The voltage waveform of the inverter-driven motor is not a sine wave voltage, but a pulse-width modulation (PWM) voltage. According to Fu Liye's analysis, this waveform ...

Confirm the rated power and resistance value of the braking resistor. The rated power of the braking resistor should be determined according to the power and moment of inertia of the motor, and the resistance value should be selected according to the specifications of the VFD. In the VFD's parameter settings, find the parameters related to the braking resistor, such as the braking resistor selection ...

The problem of the inverter is not only affected by external factors, but also by internal factors. 1. The inverter parameter setting is unreasonable and countermeasures to make the inverter work normally, in addition to the normal equipment, the parameter setting is also very important, if the parameter is not set properly, it will not be able to ...

A：a. Now only the TGM series touchscreen supports penetration as well as network connectivity b. At present, the penetration function only supports the PLC class of Xinjie that supports the Xnet protocol, and other models do not support it temporarily c. Check whether the computer has the latest version of config installed serial port equipment tool (soft ...

A universal inverter is an electronic device used to control the speed of an electric motor, which can change the speed of the motor according to the demand, and then achieve higher output power and power savings.

1. Look inside the electrical cabinet, for example, to see if there are small animals and their droppings, and whether there are condensation or water marks. If the dust in the cabinet is large, please clear the external radiator of the inverter. 2. Assuming that the humidity is relatively large, there are condensation or water marks, please open the cabinet door first, ventilate and dehumidify, you can use electric fans, etc.

Inverters are mainly divided into two categories according to the frequency conversion method: communication/DC/communication and communication/communication inverters. AC/DC/AC inverter, also known as direct inverter, refers to the operation, the first 50Hz power frequency communication power is converted into pulsating direct current through the rectifier module unit, ...
