Q:When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?
I don't know if you're a manufacturer of car gearboxes, and we've also done car engine tests. The operation in the 50HZ when the inverter is not reduced voltage, if only a little decrease will decrease, this is due to increasing frequency, controllable silicon resistance increases, the corresponding motor voltage decreased slightly, not what the essence of influence.
Q:What are the differences between the two quadrant and the four quadrant of the inverter?
The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.
Q:How does frequency converter realize variable frequency speed regulation?
The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology. The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.
Q:What is the difference between a frequency converter and a servo controller?
The inverter is actually an inverter. It is the first AC into DC. And then use the electronic element to switch DC power into AC inverter. In general. Large power SCR. And an adjustable frequency. The device can be adjusted in a certain range of frequency is used to control the motor speed. The speed can be adjusted. In a certain range. The inverter is widely used in AC motor speed.Frequency conversion motor and AC motor is not very different, but the high-frequency loss of materials used is small. Ordinary AC motors can also be frequency conversion speed regulation
Q:At the base block Yaskawa inverter is what reason?
For example: when you put the inverter to stop, there will be a signal to the inverter, then the converter will base the blockade, cut off the output, the motor will no longer work; when you need a converter work, there will be a signal to the inverter, inverter will cancel the locks on the base, and the normal work,This function is only equivalent to one protection.
Q:What does the base frequency 60Hz represent in the inverter?
How to set the frequency converter: inverter frequency parameter should be set to the rated frequency of the motor is set up, and not according to the load characteristic set, even if the selection is not suitable for motor load characteristics or parameters must also try to follow the motor, easy over-current or overload.
Q:Where is the frequency converter used?
The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in
Q:What is the working principle of elevator frequency converter?
The basic principle of VVVF elevatorAccording to the theory of motor, the speed formula of AC motor is:N=60f (1-s) /pUpper type: F is the stator frequency, and P is the pole count;S is slip; n is speed.
Q:Can not directly through the PLC, ABB converter and Kingview software communication between them?
As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.
Q:What is the frequency converter through function?
The default power loss time is 5S.Using DSU's high-power inverters, you need to set the time delay in DSU software to activate this function.The power down function is unique across some converter functions. In the power plant, semiconductor, petrochemical and other industries has been widely used to solve the power problem recurring and electricity, the massive economic losses caused momentary loss of power equipment downtime caused by continuous production. To protect the user to the greatest extent.
