The role of the inverter - LS generates electricity

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 contactor is an automatic switch in industrial electricity that uses a button to control its on/off. The contactor consists of an electromagnetic coil, a static armature, a moving armature, a static contact, a moving contact and a fixing bracket. The principle is that when the electromagnetic coil of the contactor is connected to the communication electricity, a strong magnetic field will be generated to make the center of the coil ...

Before the asynchronous motor is equipped with an inverter, let's take a look at the three major types of mechanical equipment loads: 1. Constant torque load: such as conveyor belts and mixers; When the inverter drags a load of constant torque nature, the torque at low speed should be large enough and the overload capacity should be large enough. If you need ...

LS touchers are divided into AC touchers (voltage AC) and DC touchers (voltage DC), which are used in electricity, power distribution and consumption. Toucher broadly refers to the electrical appliances that use the current flowing through the coil to generate a magnetic field in industrial electricity, so that the contacts are closed, so as to control the load. ...

The two wires are connected to the resistor, and the other wire is connected to the adjustment terminal. The red thread is attached to the blackhead and inserted in a small hole. Connect both ends of the IR potentiometer to +10V and ACM, and slide the termination to the voltage input terminal AVI. ...

Universal inverters are characterized by their versatility. With the development of inverter technology and the continuous expansion of market demand, general-purpose inverters are also developing in two directions: low-cost simple general-purpose LS inverters and high-performance and multi-functional general-purpose inverters. They have the following characteristics: ...

One. Logical stage　　 The so-called logical stage is to be able to complete the general logical planning in the relay system, since it is a relay system, so the knowledge of power drag is the foundation of this stage. I personally summarize that the root of learning the relay system lies in the word "grab", the relay system ...

Driver: Under the premise of carrying out frequency conversion skills, the servo drive has carried out more advanced control skills and algorithm operations than general frequency conversion in the current ring, speed ring and azimuth ring inside the drive (the frequency converter does not have this ring), and it is much stronger than the traditional servo in terms of function.

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.

When using an inverter, a leakage maintainer must not be used. This is a major criterion for the use of frequency converters. Some users choose the corresponding leakage maintainer for the inverter when using the inverter. *The result is: the inverter moves together ...

1. OC failure Like other inverters, overcurrent alarm is also a common fault of power inverter, in addition to the reasons for parameter settings such as acceleration and deceleration time, there are mainly the following possibilities in hardware: damage to high-power modules may cause OC alarm, low-power economical inverter ...

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 ...

When LS PLC is put into operation, its operation process is generally divided into three stages: input sampling, user program fulfillment and output rewriting. The completion of these three phases is called a scan cycle. During the entire operation, the PLC's CPU repeatedly performs the ...

According to the statistical analysis of the frequency and shutdown time of the inverter's detailed common problems, the correction rate of the main power supply circuit accounts for more than 60%; The main operating parameters are not set properly, resulting in about 20% of common problems; Common problems with control circuit boards account for 15%; 5% of common problems are caused by incorrect operation and external anomalies ...

"Servo" - the word derives from the Greece word for "slave". People want to treat the "servo mechanism" as a handy tame thing, and act in accordance with the requirements of the control signal. The rotor stands still until the signal comes; As soon as the signal arrives, the rotor rolls; When the signal disappears, the rotor can instantly ...

1. The speed of the motor slows down, and the cause of the problem of sound disorder may occur in the electronic speed stabilization device and the motor itself. If there is no problem with the power supply, most of the motor itself has a problem. It can be repaired by replacing the new motor and dismantling and repairing the motor. Dismantling and repairing the motor ...

In fact, the problems of the motor are not the cause of the motor itself, most of them are caused by the non-standard debugging of the inverter or the wrong inverter motor when the inverter motor is used, etc., mainly due to the following situations: 1. Put the general motor ...

With the deepening of factory automation, the high efficiency and low cost of active warehouses, elevators, transfer systems, etc., as well as the high speed, high efficiency and high precision of small CNC machine tools, kneading and forming machines, textile and film machinery, etc.

In March 2019, LS Group signed a strategic cooperation agreement with Country Garden to build Cisco Smart City into an innovative model for smart cities. LS Electric will provide power distribution system solutions for Cisco (Guangzhou) Smart City, providing frame circuit breakers, molded case circuit breakers, vacuum circuit breakers, miniature circuit breakers, and micro circuit breakers.

1. Confirm the location of the device Before the equipment switches on and off the power supply, it is necessary to confirm the location of the equipment, and generally require the equipment to be in a ventilated, boring, non-corrosive gas and dust-free place. 2. Equipment holder The fixed base of the switching power supply is fixed on the orientation of the equipment, and the general ...
