In the process of century industry, the more top-level software and hardware planning for the suspension of frequency conversion skills, first according to the characteristics of traditional air compressor motors, comprehensively analyze the causes of energy consumption and operation characteristics, so as to plan the control of frequency conversion skills speed regulation, air skill tightening, pressure sensing skills improvement, etc.

Xinjie PLC 丨Communication failure is generally summarized as the following problems: (1) Communication parameters: The communication parameters of Xinjie PLC communication port and peripheral equipment may be inconsistent. (2) Communication line: The connection may be incorrect, or the contact is poor, the user can replace the communication line and try again.

Motion control has a significant period characteristic, it is a variety of high-tech generalization, used to bring industrial automation, office automation and home automation to a higher stage. Nowadays, motion control is mainly composed of variable frequency drive (VFD), electric motor, control ...

Although many relays, timers and counters are often used in the ladder diagram programs used by PLCs, PLC does not have these hardware physically, but uses memory and program programming methods to do logic control and editing, and connects external mechanical devices to make physical devices through output components.

Why can't the touch screen software be installed or used properly? 1. Before the device, please close the antivirus software and system optimization things; 2. After the device is successful, double-click the software convenience icon on the desktop, "Please set the display to be true color" prompt ...

(1) Whether there is an abnormal change in the sound during the operation of the motor, including whether there is vibration during the operation of the motor. (2) Whether the installation environment of the inverter has changed. Whether the ambient temperature is normal, the operating temperature of the inverter is generally required to be in the range of -10 °C - +40 °C, and it is better to take about 25 °C.

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 ...

1. On the premise of satisfying the production equipment and process requirements, the acceleration or deceleration time should be increased as much as possible, and then the overcurrent generation in the process of acceleration or deceleration can be avoided. 2. Check whether the inverter, motor, and production equipment are well matched, whether the transmission part is sensitive, and whether the material is ...

Motor overload: There is no need to set overload maintenance parameters in frequency conversion. The inverter generally acquiesces to the motor overload maintenance based on the motor power. Generally, it is 1.2 times 60 seconds to report the overload problem. The overload factor is not the same for different frequency converters. ...

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 ...

The usual inverter motor (hereinafter referred to as VFD) can only regulate the speed of the communication motor, and it can be open-loop or closed-loop, depending on the control method and VFD. This is the traditional V/F mode. The basic concept of servo is accurate, precise and fast positioning. Frequency conversion is servo ...

1. Common problem phenomena When the RS-485 port of the PLC is connected to the computer through the non-blocking PC/PPI cable, the connection between the PLC and the PLC, or the communication between the PLC and the inverter, touch screen, etc., the communication port is damaged, and the more common damage conditions are as follows: (1) R1 or R2 is burned ...

The grounding policy is nothing more than to avoid disturbance for safety, and the policy of grounding to PLC must not be attached to the disturbance at the power supply and input and output terminals, so the accurate grounding system is one of the primary methods for the PLC control system to resist electromagnetic disturbance. There are floating and direct grounding formations.

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 ...

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is the numerical control system, the numerical control system can logically process the program with the control code or other symbolic instruction rules, and decode it, so that the machine tool action and add ...

The motor soft starter is a new type of starting equipment designed and produced by using power electronics skills, microprocessing skills and modern control theory. The motor soft starter can effectively limit the starting current of the AC asynchronous motor when starting, and can be widely used in wind ...

(1) What is the current setting value of the thermal relay? The setting current of the thermal relay refers to its action current, that is to say, it is adjusted between 0.95 - 1.05 times of the rated current of the motor being maintained.

W-BOX is a 2.4GHzWifi-based wireless communication module independently developed and recently launched by Xinjie in line with the trend of wireless communication. W-BOX can be connected with wireless AP (hotspot) in various occasions to complete long-distance monitoring of PLC and overall control of PLC wireless networking in various environments.
