The origin orientation is incorrect, and the encoder debugs/zeros the bit First, the value of the current at each branch is calculated (1) Purely resistive loads, such as bulbs, electric heaters, etc., are directly divided by the indicated power by the voltage. Formula I = power/220v; ...

Circuit breaker action time test. The closing and opening control lines of the circuit breaker mechanical characteristics tester are respectively connected to the secondary control line of the circuit breaker, and the lead wires of each break of the circuit breaker are connected to the mechanical characteristics of the circuit breaker with the test wiring.

1. Aluminum alloy shell or steel plate welding, plastic spraying on the surface; 2. Built-in inverters, circuit breakers, signal lights and other components produced by domestic or Schneider and other companies; ​ 3. It mainly regulates the general three-phase difference by changing its output frequency.

1. In terms of logo, the logo of the product is a sign of identity, so the genuine products will be very exquisite. The imitation is not very well handled on the logo, the plane contrast above the letter "A" is narrow, and even the top is directly pointed. We must pay attention to this point. 2. From ...

According to the statistical analysis of the frequency and shutdown time of the specific common problems of the inverter, the repair rate of the main power supply circuit accounts for more than 60%; The main operating parameters are set improperly, resulting in about 20% of common problems; 15% of the common problems of manipulating circuit boards; 5% of common problems are caused by incorrect operation and external anomalies ...

(1) Whether the closing condition of the isolation switch is not defective, and whether there is any failure or dislocation; (2) The porcelain insulation of the isolation switch should be free of defects, no cracks, no discharge phenomena and flashover traces; (3) Contact inspection: a. Check the contact ...

1. What type of ATS48 power supply is? The control power supply of ATS48 selects communication input, and supplies power to the controller, input and output ports through internal power processing; The control power supply of Q series products is 220V-415V; Handling of the Y-Series ...

1. Contactor refers to an electrical appliance that uses a coil to flow through an electric current to generate a magnetic field, so that the contact is closed, and then the load can be controlled. Because it can quickly block the main circuit and frequently connect the equipment with high-current control circuits, it has been widely used in electrical engineering.

1) Survey and research method. The investigation and research method is to understand the obvious problem phenomena through "seeing", "listening", "smelling", "touching" and "asking"; After visiting the operator, understand the cause of the failure; A common way to help find the fault point after asking others or consulting information ...

1. Use the analog output port to indicate the motor frequency, when the motor frequency is 50Hz, why is the output only 16mA? Due to the maximum output frequency parameter of the inverter "TFR", the factory default value is 60Hz. So when the inverter output is 50Hz, the analog output is 16mA. At this time, only ...

There are three main differences, namely: different uses, different products, and different characteristics. 1. Different use cases: The programmable manipulator produced by Siemens in Germany is also widely used in China, and has been used in metallurgy, chemical industry, printing production lines and other fields.

The AC-DC inverter main circuit consists of three components: the rectifier main circuit, the center circuit and the inverter circuit. 1. The main circuit is the power replacement part that provides voltage regulation and frequency regulation power supply for the asynchronous motor, and the main circuit of the inverter can be roughly divided into two categories: the voltage type is the voltage source ...

Fault 1: The shell of Schneider MCB product is yellowed or burned. Reason 1: It is very likely that the magnetic coil inside the circuit breaker is burned out because of harmonics or high-frequency signals. Method 1: * The good thing is that the filtering can be satisfied with the use of 50Hz/60Hz power frequency. ...

1. The need for stability When choosing UPS products, the customer's focus must be stability. For UPS, higher power means lower calorific value. Of course, only one of the primary factors that affect the internal temperature of the UPS is also to consider the heat dissipation planning of the machine itself. ...

1. Insist that the air is moist or unclean, and the pipes are not clean, which may have the following consequences: (1) The wet gas is decomposed into mixed gases such as hydrogen and oxygen under the effect of arcing, destroying the insulation between the fractures after the main contact is broken, which is difficult to arc or arc re-ignition, and in severe cases, arc extinguishing will be formed.

1. Question-F 05 (frequency error): This problem is caused by a problem with the soft starter processing the internal power signal, which is causing errors in the power supply frequency. This situation needs to be handled by the company's product development software design engineer. Mainly start the power supply circuit design ...

1. Type recognition: Recognize whether the type of inverter is common with the type of inverter purchased. 2. Transportation acknowledgement: After opening the package, check whether the inverter is damaged during transportation. 3. Voltage recognition: the power supply voltage on the site should be borne by the inverter.

1. AL001: overcurrent, the current value of the main 2113 circuit exceeds the motor instantaneous 5261*** high current value 1.5 times when the action is 4102. 2. AL002: overvoltage, the voltage value of the main return 1653 channel is higher than the standard value. 3. AL003: low voltage, the voltage value of the main circuit is lower than the standard.
