The touch screen controls the inverter steps

Change the shutdown mode to inertia parking and you're done! In this way, after the fan is stopped, the inverter will immediately turn off the output, so that the fan can stop freely, at this time, although the fan is in the power generation situation, but the electricity generated by the fan will not pass through the inverter of the inverter to generate direct current, so the inverter will not overvoltage ...

There are many functional parameters of the inverter, and there are generally dozens or even hundreds of parameters for users to choose. In practice, it is not necessary to set and debug every parameter, and most of them only need to use the factory setting value. However, some parameters are very closely related to the application of practice, and some of them are still ...

1. Check the running status of the inverter, whether the voltage and current value during operation are within the normal range. 2. Carefully monitor and record the ambient temperature of the frequency conversion chamber, which is generally between -5 °C and 40 °C. The temperature rise of the phase-shifting transformer should not exceed 130°C. 3. Prevent ...

There are many categories of PLC, and the following is a brief introduction to PLC and its main functions 　　As an innovative PLC product family that combines the technical capabilities of power production and production, XGT is a system based on open networks, ultra-high-speed processing speeds, compact size and a large number of improved software.

1. The power value of the inverter is the most suitable for the power value of the motor, so as to facilitate the operation of the inverter at a high power value. 2. When the power classification of the inverter is not the same as the power classification of the motor, the power of the inverter should be as much as possible.

Due to the short circuit of the load, the failure of the self-oscillation circuit and the loss of control of the protection circuit, the switching power supply will cause the base of the switch tube to be unable to get the switching pulse and intermittent operation, which makes it difficult to locate the shortcomings of SMPS. The difficulty of the repair operation and the improper method will expand the shortcomings, constituting the phenomenon of continuous burning of the switch pipe, etc., ...

1. Speak before you start When it comes to faulty electrical equipment, you should not rush into action, but ask about the passage and phenomenon of the fault. For unfamiliar equipment, you should also understand the circuit principle and structural characteristics, and follow the corresponding rules. Before dismantling, it is necessary to fully understand each ...

1. The load is too heavy, the load carried by the motor is too heavy, or in other words, the resistance torque of the production machinery exceeds the additional torque of the motor. 2. Use improper overload, for example, increase the operating frequency of the inverter to the extra frequency of the motor, and the motor is in the extra frequency.

K120S series PLC product is a unit PLC product introduced to the market by LS in 2004, which has laid a solid foundation in the low-end small machinery supporting industry with its high-performance price ratio. Relying on some special functions of the product, it has also won some industry praise. ...

What is the reason why the contactor keeps engaging and disconnecting by pressing the start button after the AC contactor is energized? In my personal opinion, most of the situation is caused by the wrong coil voltage of the replacement AC contactor, or the purchase of ...

The working principle of the power production contact is: when the contact coil is energized, the coil current generates a magnetic field, and the generated magnetic field leads the static iron core to produce electromagnetic attraction to the iron core, and drives the AC contact action, the normally closed contact is disconnected, the normally open contact is closed, and the two are connected to each other. When the coil is de-energized, the electric ...

The peripheral equipment of the inverter mainly includes cables, contactors, air switches, reactors, filters, braking resistors, etc. Whether the selection of the peripheral equipment of the inverter is correct and suitable also directly affects the normal operation of the inverter and the service life of the inverter.

The method of vector control frequency conversion speed regulation is to change the stator current Ia, Ib, Ic of the asynchronous motor in the three-phase coordinate system, after the three-phase - two-phase change, equivalent to the communication current Ia1Ib1 under the two-phase static coordinate system, and then after the directional rotation according to the rotor magnetic field, it is equivalent to synchronous rotation sitting.

Each type of servo motor has additional torque, maximum torque and servo motor inertia and other parameters in the standard items, each parameter and load torque and load inertia must have a relevant connection, the output torque of the servo motor should meet the requirements of the movement conditions of the load organization, such as the speed of the acceleration ...

The inverter should be installed inside the control cabinet, and the following problems should be paid attention to when planning the control cabinet: 1) Heat dissipation issues: The heating of the inverter is caused by internal losses. In the inverter, the main circuit is the main circuit for the loss of each part, accounting for about 98%, and the control circuit accounts for 2%. ...

(1) The core noise is large: it is normal for the electromagnetic system to produce a slight humming sound during operation, if the sound is too loud or abnormal, it can be judged that the electromagnetic system has a problem, and there are three reasons: (1) Poor contact between the armature and the core or tilting of the armature. After repeated collisions between the touch of the armature and the core, ...

From the point of view of application, the function that should be reached is: it is necessary to conduct the local area where the touch part should be conducted, and the touch is reliable. If the insulating part should not be conducted, it is necessary to insulate it firmly. There are three common types of faults in terminal blocks: ...

1. Physical environment (1) Temperature factor Temperature has a huge impact on the lifetime and reliability of the electronic components inside the inverter. When using the inverter in a high operating temperature environment, it is necessary to take additional cooling measures to ensure that the ambient temperature is stable in the inverter.

The Electronic Motor Relay (EMPR) is a digital motor maintenance relay with an MCU that has a compact and compact form factor that can be combined directly with a contactor. Through the implementation of real-time data processing, high reliability and high precision can be completed, and it can pass through phase loss, reverse, unbalance, stalled rotor, connection...

An important difference between servo and frequency conversion is that frequency conversion can be without encoder, while servo must have an encoder for electronic commutation. 1. What the two have in common: The AC servo technology itself is to learn and apply the technology of frequency conversion, and the servo control of the DC motor is based on the ...
