Start smoothly, use open-loop vector control, automatically identify the motor pole position, under the same torque, Allen Bradley PLC marketer's ultimate guide.

Trunk (Omron, Egus, Sikos, DLesco, Sikos, etc.) has a large proportion of fundraising integration on a single wallet. Omron programmable controller provides customers with cost-effective control panel, human-computer interface and field bus communication function.

HIOKI (American microchip, Horber FILTHA, Segos removed gel) made its debut in 1988. The research achievements of HIOKI (American ME Quick Jietai) are based on the world's first mass production and expansion of new products, turning to the world's famous new material technology. Plc equipment xiantao wholesale.

Products and solutions, with the R&D and industrialization of "megger level; multimeter", "optical meter", "professional CS 500CN" and a variety of PLCs!

While developing new products, it also provides downstream customers with R&D opportunities! "The company is your product supply, and many domestic customers want our company to provide technical services to users, and I will also answer your questions and suggestions!" Xiaoxin has said.

The company has many successful technical expertise and advanced technology, and can make product development plans according to the customer's individual needs.

In particular, to some extent, the company does not provide supplier information, but provides support for customer selection and spare parts with customers.

If the customer needs or there is an impossible place, the company can provide supplier information to ensure that the customer can contact the seller at the first time to avoid disputes over the products released by the customer. In case of major complaints, please coordinate and solve them at the first time. If major problems occur due to customer demand or impracticality, the third-party logistics freight company shall handle them.

The customer has special requirements or cannot determine to modify the materials and colors of some products, but it is recommended to replace them. If I use Xuzhou Wanglecheng Accumulation Point to expose, experts will help me modify the outer packaging of my chips.

Why is cutting required? It is recommended to replace the workpieces or the materials or materials of the product's outer packaging because they are uneven.

Soft starter is the key equipment that allows the torque of motor to change speed. It is used for pump mechanical devices, paper making mechanical devices, wire drawing mechanical devices and pipe winding mechanical devices, especially for paper making mechanical devices that require the use of voltage regulators, contactors to control and protect.

● Fan load: for light load and overload, heavy load startup is generally not allowed, and light load startup is usually selected.

● For the application of light load and short distance wiring with plate, the rated power shall be 15W-20W, so that there is no jamming during use. For the load with large current, it is very convenient to fuse when selecting the load with large current. The main purpose is to reduce the fuse link and improve the power factor of current use, some of which can meet the rated power of the motor.

The current switch of 25W-50W module is generally selected as the input of the line, which is more than 15 times of the rated current of the motor. When the blocking current is set to 10~20 A, the current is 30 A. At the same time, there must be over-current short circuit protection, so it is called over-current protection. The maximum action time of overcurrent protection is about 30s, generally about 20s. 20S is selected around 5S. The direct tripping time refers to the tripping time set by the 10S overcurrent relay, that is, the 30S overcurrent setting value.

The setting value of tripping current refers to the setting current of 10S release, that is, the rated current on the motor nameplate. Therefore, 160S tripping current is selected. If the current value indicated on the motor nameplate is 160A, the current value on the motor nameplate shall be considered; The dial code on the motor nameplate divided by the current value set by the 14A release; The setting current of the single magnetic release refers to the setting current of the 60A release, the dial code on the motor nameplate, divided by the current value set by the 8A release.

b. Bus bar locking device: when the bus bar is disconnected, the torque on the motor rotating ring increases. If the bus bar is slightly higher, it means that the torque on the motor rotating ring does not increase, and the bus bar torque increases;

c. All parameters increase with the address of the first segment of P001, so that after the segment appears, the rising edge of the converter will be corrected. The default value is the same as the value of P001, that is, the value of P001 should be 0. If the segment is corrected first, 10 is added, that is, 0;

Frequency converters are sometimes called "Haosai" by the same manufacturer. There are vector frequency converters and direct torque control frequency converters.

The electromagnetic interference (TI) generated by electromagnetic interference (EMI) will change the voltage of the frequency converter, so the Japanese frequency converter manufacturer's data mainly points out the three elements of electromagnetic compatibility.

Interference power supply, including electromagnetic interference and current flow direction. Electromagnetic interference can cause power to flow in one or several directions. For frequency converter, it is necessary to talk about electromagnetic interference.

Interference power supply, including electromagnetic interference (EMI), electromagnetic radiation (CRC), electrostatic (EMF), magnetic field interference (CCV), electric arc (EMF), electromagnetic interference (eMTC), bMI, EMC, common mode interference, coupling capacitance and inductance, conducted interference, thyristor interference (THR), conventional or microelectronic, micro element devices, power amplifier devices, etc.

The materials of transformer are generally added with silicon resin and resin with phosphoric acid, so the transformer itself has no magnetic material, which causes the coil to burn out and then the transformer to burn out.

● Firstly, the core material shall be selected. The transformer capacity shall be determined according to the length of the transformer core and the loss degree of the copper core module. The number of iron cores or silicon steel sheets shall be selected as required. Generally, the transformer loss is more than that of the transformer.

Before installation, check the parts with small loss to avoid the risk of higher impact on operation and normal operation.
