The difference between Schneider and Siemens PLC

1. After the inverter is repaired, the power number demand is corrected, don't forget Generally, an inverter corresponds to a power number (also known as the number of horsepower), for example, a 75 kilowatt inverter is set under heavy load, and 100 kilowatts is set under light load. In this way, the customer will not use it to present ...

1. The number of braking resistor boxes is roughly calculated as: motor power (KW)/11.2 (take the upper limit of the integer). 2. The selection of the power of the braking unit is generally (1-2) times the power of the inverter; 3. The function of braking resistor ...

When the inverter is used to form an automatic control system for control, in many cases, PLC and inverter are used together, and how to correctly connect the PLC and inverter together has become the key to the success of the system. 1.PLC switch ...

It should be basically stored in the plate, the problem is that the plate with a fully enclosed structure is large, takes up a lot of space, and the cost is relatively high. This can be done by: (1) The planning of the disc should be based on the heat dissipation required by the actual device; (2) Profit ...

The contact orientation is 100% secure As for the circuit breaker, the indication of the handle can also be said to be the fault indicator of the circuit breaker, if it is "blurred" for a while, it may cause irreparable damage. Therefore, according to the requirements of the national standard, in any case, the hand of the circuit breaker ...

The test input does not conform to the "short" rule, and the problem is here. 1. Overhaul according to the comparator rules, fit it, the piece is good, and check the periphery; It doesn't fit, the piece is bad. 2. It does not fit the "virtual break" - there are ...

1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is in normal operation, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in operation, and do the corresponding recording operation; When repairing the inverter, check whether the voltage value and current value exceed the promised ...

1. Copy and copy through the Chinese panel. Older inverters, if they support Chinese panels, such as ATV71, ATV61, etc., support VW3A1101 panels, they can use the proprietary 'open/save as' parameter on the panel to copy and copy, and the newer ATV610, ATV630, ATV930, ...

Drives power and operate commercial and industrial motors, and thermal protection is necessary in accordance with their planning and operating environment. The main advantages of the frequency converters are flexible handling, smooth start-up and shutdown functions, and significant energy savings due to centrifugal fans and pumps operating under variable loads. ...

The given frequency refers to the frequency at which the inverter is set to operate, and the given frequency can be given by the operation panel or by the external method, during which the external method is divided into voltage and current. First, the operation panel is given a frequency ...

An air switch, also known as an air circuit breaker, is a type of circuit breaker. It is a switch that only needs the current in the circuit to exceed the rated current will be actively disconnected, and is generally used to avoid circuit overload and short-circuit maintenance (some also have low voltage maintenance functions) can not maintain electric shock, to put it bluntly, it is ...

Most of the motors used in the industry are of this type. The rotational speed of an induction AC motor (henceforth referred to as a motor) is approximately determined by the number of poles and frequency of the motor. The number of poles of the motor is fixed by the working principle of the motor. Since the pole ...

In order to keep the main Schneider circuit breaker in excellent operating condition, it is necessary to strengthen the maintenance management. 1. Insist that the air is moist or unclean, and the pipes are not clean, may have the following consequences: (1) The wet gas is decomposed into mixed gases such as hydrogen and oxygen under the action of electric arc, which damages the ...

1. The control accuracy of the vector type is higher than that of the general-purpose type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, which is suitable for application in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If used in some of the more common fields ...

1. How to complete the control of ATV38 and ATV58 through the operation panel? First, in the control menu, set "LCC" to "YES" (panel operation); Enter the "LFR" parameter in the adjustment menu, press the up and down keys to adjust the given value, and complete the control of the inverter. ...

In order for the inverter to operate normally, it must have two basic conditions, that is, the frequency signal and the operating signal, let's talk about the first condition, which is the frequency signal of the inverter. Our intention to use the inverter is to change the ...

Inverter terminal blocks belong to a kind of connector, the variety is divided into single hole, double hole, socket, hook, etc., from the data point, copper silver plating, copper galvanized, copper, aluminum, iron, etc. Their effect is mainly to transmit electrical signals or conductive use, in the project, it is the station front engineering for the station after the project reserved for the connection ...

Don't worry about the damage of the frequency conversion, disassemble the machine after the discharge; It is indispensable to ask for a diagnosis and clarify the problem at the beginning of the test; Input and output PN junction, three-phase balance and then unshelling; Look at the nameplate before powering on, the wrong voltage will blow up; The bus has no electricity to see that it is safe, and the rectifier filter is wrong ...

Beijing, China, September 14, 2020 – Today, the 5th China Power Distribution Technology Summit Forum 2021, held by China Electric Power Research Institute Co., Ltd. and the Science and Technology Development Service Center of China Electric Power Council, opened in Beijing. The theme of this forum is "Supporting the Strategic Policy of Carbon Peaking and Carbon Neutrality, Building a ...

1. Select the inverter according to the load characteristics. 2. When selecting the inverter, the actual motor current value should be used as the basis for the selection of the inverter, and the additional power of the motor can only be used as a reference. Secondly, the output content of the inverter should be fully considered.
