1. The switching quantity is also called the logical quantity, which means that there are only two values, 0 or 1, ON or OFF. It is the most commonly used control, and it is the advantage of PLC to control it, and it is also the most basic use of PLC. The intention of switching quantity manipulation is to use the current input combination of the switching quantity with the historical input ...

There are many novices who are not familiar with the false load about the maintenance inverter, and the maintenance inverter uses the false load to keep many of their modules, because the maintenance novice generally does not know how to do this, and now the electric light is on to clarify that the module is going to be broken. A dummy load is a load with a resistor of several hundred ohms ( ...

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 ...

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. Universal inverters have a wide range of application scales and can be used for various types of electric motors, including communication motors, direct ...

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 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 ...

Assuming that the inverter has a long service life, heat dissipation must be carefully considered. Because the equipment failure rate of the inverter increases exponentially with the increase of temperature, the service life decreases. If the operating temperature rises by 10 degrees, the service life of the inverter will decrease. ...

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.

Since the advent of the MS6 series B1 and B2 servo motors, they have been widely recognized by customers for their outstanding performance advantages, and their performance in terms of temperature rise, overload ability, overspeed range and protection level is far better than that of MS5 series servo motors. This MS6 series B3 motor released will ...

At present, in the domestic PLC market, there are many kinds, but there are not many domestic PLC manufacturers with real strength, most of the domestic PLC is not an individual who does not have the qualification of a legal person, or a single-chip microcomputer enthusiast, from the domestic PLC factory to buy the underlying programming code or buy a domestic PLC chip (the domestic P that burns the underlying code...

World electrical safety standards: The requirements are in line with the world's electrical safety standards, such as the CE standard in Europe and the UL standard in the United States. These specifications specify the requirements for electrical safety functions, mechanical safety functions, EMC functions, etc. Machine...

When we select the right inverter brand, we need to recognize whether it can help enterprises better manage the risks and costs caused by potential safety, security and downtime accidents. Safety: Reverse arc drives assist users in meeting stringent reverse arc specifications. These inverters (Variabl ...

1. Save the transformation cycle, no need for large-scale construction: eliminate the trouble of wiring maintenance, and easily complete the transformation within one day and meet the requirements of communication stability. 2. The device is simple, no programming is required: the wireless communication terminal only needs to ...

The primary role of the TP contact screen Supervision: Reflect the internal bit status of the PLC in various ways such as data, curves, graphics, animations, etc., store the numerical value, and then intuitively reflect the process and direction of the industrial control system. Exercise...

1. Acknowledging the characteristics of the load such as load type, speed, and nature; 2. Acknowledging whether it is continuous work, long-term work, short-term work and other work characteristics; 3. Acknowledging the maximum consumption output value and the extra output value; 4. Acknowledging ...

PLC programmable logic manipulators are the core part of industrial control. According to the number of I/O points of PLC, PLC can be divided into three categories: small PLC, medium and large. It is a digitally operated electronic device designed for industrial production. It uses a programmable memory to store programs that execute user-facing ...

XC can be divided into multiple sub-series according to the incompatibility of functions, including XC1 (economy), XC2 (foundation), XC3 (standard), XC5 (enhanced) and their corresponding expansion modules, as well as special imitation ontology, activity control models, etc. Powerful function, complete variety, can be full ...
