Delixi inverter control motor problem

1. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. To achieve voltage regulation, it is the demand control system (negative feedback), from the automatic control theory, we know that when the voltage rises through negative feedback to reduce it, ...

1. There is no output, no voltage indication or no start when the machine is turned on. Overvoltage or undervoltage maintenance 1. Adjust the internal output voltage adjustable potentiometer 2. The wrong phase and the lack of phase are maintained, and the two phases are arbitrarily replaced by three phases 3. The main control circuit board is broken 3. Replace 4. The output AC has been ...

1. Trial delivery and commissioning method The first thing to find is the fault of the remaining current action maintainer itself. The detailed operation method is: first block the power supply, and then remove all the zero-sequence transformer load side leads of the remaining current action maintainer (the second and third level remaining current action maintainers will directly remove the outgoing ...

Single-beam crane throughout the use of electric hoist as a lifting mechanism, with a simple structure, convenient use, widely used in some lifting tonnage small industrial and mining enterprises, domestic hoist crane throughout the use of conical rotor motor, cone motor structure than the general motor messy, ordinary method speed regulation is more difficult ...

1.AC/DC the use of power supply Schematic diagram of the use of low-dropout linear regulators in AC/DC power supplies. In this circuit, the AC voltage is stepped down by the power transformer to obtain the low voltage of communication, and then the unstable DC voltage is obtained through the rectifier filter circuit, and then the voltage is regulated linearly by the low dropout ...

According to the controlled target and operating parameters such as voltage, current, power, frequency and operating system, the additional parameters of the contactor are determined. 1) The coil voltage of the contactor should generally be lower, so that the insulation requirements of the contactor can be reduced, and it is safer to use. But for the sake of the party ...

All large AC power blocks are transmitted and distributed at high voltage levels via a three-phase transformer. Single-phase transformers can be electrically connected to form a three-phase transformer bank in a distribution system. But the standard is to combine a single phase coil into a three-phase transformer unit on a common core ...

　　The principle and operation method of Delixi inverter: 1. No-load energizing test of inverter 1. Ground the grounding terminal of the inverter. 2. Pass the power input terminal of the inverter through the leakage maintenance switch.

As far as miniature circuit breakers are concerned, 1P+N, 1P, and 2P are generally used as the on-off control of single-phase electrical appliances, but the functions are different. In order to facilitate the user's selection and difference, the difference of the P number of circuit breakers and the selection method are briefly analyzed. ...

1. Under what circumstances does the leakage maintainer not maintain the electric shock? The leakage switch models commonly used in general families are 1P+N and 2P, as far as the leakage maintainer of 1P+N and the leakage maintainer of 2P (single-phase electricity maintenance) are concerned, when people touch the zero line and the front together, people are touched.

At the end of July, Delixi Electric launched a new 6 series CDW6i structural circuit breaker and a number of industrial control accessories. The new 6 series CDW6i structural circuit breaker has complete product specifications, which can provide professional customers with more choices, excellent functions, and ...

Quickness: It means that the maintenance device should be able to remove the short circuit as soon as possible, and its intention is to improve the stability of the system, reduce the damage to the peak equipment and lines, reduce the scope of the process, and improve the effect of active overlapping room and standby power supply or standby equipment active investment. ...

The spring is a widely used component in the circuit breaker mechanism, and the critical spring has a great impact on the function of the circuit breaker. From the perspective of energy, combined with the installation space of the tension spring, the author uses the existing accounting formula of the tension spring to solve the unknown quantity from the known quantity to obtain the required tension spring parameters.

Variable-frequency drive (VFD) is an electric power control device that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the power supply for motor operation. The inverter is mainly composed of rectifier (communication to DC), filtering, inverter (DC to ditch) ...

Problem depiction: The data of Delixi inverter controller is unstable, and sometimes there is a deviation, how to deal with it? Solution: This is the result of severe disturbance of the controller. Often the controller ...

　　Since 2003, when he was first elected to the National People's Congress Committee, Hu Chengzhong, the current chairman of the executive president of Delixi Group, was re-elected as the National People's Congress Committee for two consecutive terms, and in 2018, he was once again elected as a representative of the people from all over the country.

1. First carry out the no-load test operation of the inverter First of all, check whether all the wiring of the inverter is correct, do not connect the output of the inverter to the motor, and conduct a no-load test on the inverter first. Read the user manual of the inverter carefully before powering on to understand the relevant functions and settings, and operate ...

1. Avoid water and air entering the transformer (1) The transformer should be protected from water ingress and moisture during operation, and it is necessary to seal well the cap of the casing item, the top of the storage phase, the bushing pipe and its connecting pipes. If necessary, a leak detection test should be carried out, and if the insulation has been found to be damp, it should be adopted in time.

1. According to the load type, confirm the type of inverter: different load types, speed requirements and power size, and the need to choose different types of Delixi inverters. Therefore, it is necessary to understand in detail the type of motor load to be controlled to find the most suitable type. ...

Delixi's communication contactor is widely used in industrial electrical, contactor as a kind of electromagnetic switch, its interior is mainly composed of the main and auxiliary contacts and electromagnetic coils, static cores and other parts of the control line connection and breaking. ​ ...
