Mark point, also known as reference point, provides measurable points for all processes in the surface mount process to ensure the final positioning accuracy.

The damage of the inverter to the motor contains two aspects, the damage of the stator winding and the damage of the bearing, this damage usually occurs in a few weeks to more than ten months, the detailed moment and the inverter brand, the motor brand, the motor power, the inverter carrier frequency, the cable length between the inverter and the motor, the ring ...

The fundamental characteristics of the three major control systems of PLC, DCS and FCS At present, there are three major control systems in the operation of industrial processes in continuous process production, namely PLC, DCS and FCS. The fundamental characteristics of each of them are as follows: 1PLC (1) From the development of switching control to sequential operation...

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 ...

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 ...

First, let's talk about PLC first About PLC, don't just see the PLC module, but a variety of PLC modules + host computer channel software to form a well-structured control systemPLC module is composed of microprocessor + memory + firmware + programming to complete the modular function. PLC control system ...

1. Check the full-load power supply of the inverter (Variable-frequency Drive (VFD). 1. Ground the terminal strip of the VFD. 2. Type the switching power supply of VFD into the terminal and receive it from the switching power supply through the power switch of the leakage protector. 3. ...

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.

XDM Series Sport Control (Control Points: 24/32/48/60) Support basic motion control instructions, can realize two-axis linkage, interpolation, follow-up and other functions, can achieve 4-axis independent pulse output, up to 10-axis pulse output, together to support almost all of the standard PLC...

1. High reliability The PLC adopts a series of anti-interference methods in hardware and software, so that it can be directly installed in the industrial site and operate safely and reliably, anti-magnetic, anti-seismic and dust-proof. 2. Programming is simple and easy to grasp ...

The MS series of servo motors can be installed in either the horizontal or vertical direction. However, if it is installed incorrectly, or in an unsuitable place, it can shorten the life of the motor or cause unexpected accidents. 　　Storage temperature In the unpowered state ...

Introduction to the glass sealing industry As a relatively old industry, the vitality of the glass industry has further burst out in the modern society, due to the social development and the improvement of people's aesthetics, the demand for glass in all walks of life is also increasing, which is also more abundant.

(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.

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.

　　 Wireless module introduction: W-BOX-T: Wireless WIFI module, XC, XD series can be used, occupying RS232 port; S-BOX-T S-BOX: 433MHZ MODULE, XC AND XD SERIES CAN BE USED, OCCUPYING RS232 PORT; XD-E1WT-A ...

The voltage waveform output by the inverter is similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components, especially the higher harmonics will increase the output current of the inverter, form the motor winding heating, produce vibration and noise, accelerate the aging of insulation, and even ...

The suffix is XT and only supports RS232 communication, 4 inches out. The suffix MT supports RS 232/485/422 communication. The suffix is UT on the basis of MT, and a U disk port is added, which can be used to import and export engineering and CSV data from U disk. The suffix is named ET and is added to the UT ...

The most direct cause of cable problems is the breakdown due to the loss of insulation. First of all, there are: a. Overload operation. Long-term overload operation will increase the temperature of the cable, aging the insulation, resulting in breakdown of insulation and degradation of construction quality. b. Electrical: the construction process of the cable head does not meet the requirements.

The World Economic Forum (Davos Forum) Annual Meeting 2016 will be held in Davos from 20 to 23 this month, with the theme of "Mastering the Fourth Industrial Revolution". ...
