Q:What does "G" and "P" mean in the converter model?
General inverter said, "G" and "P" type refers to the inverter general type and fan pump difference, G type inverter applies to the general machinery class load, and P type is used in the wind or water pump.
Q:What is the difference between a frequency converter and a saver?
1, through the intelligent online detection control system, closed-loop control can be completed, to keep track of changes in the load, load, change the machine output parameters, meet the requirements of the production process for customers, when customers need full load motor, motor output is not enough.For example: a plant water pump, motor speed can be supplied to a 100 force, the force is now 80, with the inverter directly to the 20 removed, and if the production process of the customer needs to provide 100 force, there will be a lack of motivation, affect the customer's production process and product quality. Such as the installation of our power class Saver, will not be the case, it can change the parameters at any time according to the requirements of the load, to ensure the normal supply of power.
Q:What is the difference between inverters and inverters?!!
The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.
Q:How do two inverters synchronize?
First of all, to determine whether the speed of the two conveyor is very strict (there is strict relative position requirements), if not, can use the following program:1. use a double potentiometer to tune two inverters simultaneously, one with a potentiometer to adjust the ratio between the two.
Q:Schneider 303 4KW frequency converter F 013 trouble shooting method
You see when the alarm is started, or stable operation alarm amount, different times, different analysis
Q:What is the difference between a converter and a transformer in Yu Na?
The main function of the transformer is to change the voltage, and to solve the problem of voltage magnitude (amplitude, RMS)The main function of frequency converter is to change frequency and solve the problem of voltage and frequency.The main application of frequency converter to motor is to adjust the speed of motor by adjusting frequency. Because the speed of the motor is related to the frequency of the power supply. Can play a role in energy saving.
Q:What does "frequency" in household appliances mean?
The technology of frequency conversion technology called frequency conversion technology and home appliances in 1970s AC control by changing the frequency of the AC current, household appliances gradually began to appear frequency, electromagnetic cooking device, inverter lighting apparatus, inverter air conditioner, microwave frequency, variable frequency refrigerator, IH (induction heating cooker), inverter washing machine etc.. In the latter half of 1990s, household appliances relied on frequency conversion technology, mainly aiming at high function and power saving. For example, with high speed, high output, good control performance, small light weight, large capacity, high comfort, long life, safe and reliable, mute, power saving and so on.
Q:Frequency converter closed loop control, frequency converter must use PG card?
Using PG card of frequency converter to realize closed loop vector controlFor example, vertical motion loads, such as cranes and elevators, require closed-loop vector controlIn this case, the frequency converter must install the PG card, and the encoder signal will be connected to the PG card, using the frequency converterPID instruction.In this application, the PID function module of PLC can not realize the vector control function.
Q:What is the main harmonic produced by a transducer? How about the degree?
The main hazards are:(1) the possibility of resonance in the power grid is increased, thereby causing high overvoltages or overvoltages to cause the risk of accidents.(2) increasing additional losses, efficiency of transmission and electrical equipment, and utilization of equipment.(3) make the electrical equipment (rotating motor, capacitor, transformer, etc.) run abnormally, accelerate the insulation aging, and shorten their service life.
Q:What are the contents of frequency converter maintenance?
Routine inspection itemsShould first check the temperature and humidity of the surrounding environment before power on, too high temperature will cause the inverter overheat alarm, will directly lead to serious damage, the inverter power devices short circuit; air is too humid will lead to internal direct short circuit inverter. In the inverter operation, should pay attention to its cooling system is normal, such as: whether the exhaust air flow smooth, fan whether abnormal sound. General protection level higher frequency converter, such as: IP20 or more frequency converter can be directly installed
