The touch screen is the interface between people and machines in the field of information exchange and function contact or interact with each other,
Information exchange, functional contact or mutual influence, the hard contact and soft touch of a person and machine,
This interface includes not only the direct contact point, including long-distance information transmission and control function space FR-F740P-220K-CHT Applied Manual FR-F740P-220K-CHT Instruction manual.
The man-machine interface is the central link in the man-machine system,
Mainly from the safety engineering branch of the safety ergonomics to study and put forward the basis for the solution,
And over safety engineering equipment engineering,
Safety management engineering and safety systems engineering to study the specific solutions and measures of the safety of human computer science FR-F740P-220K-CHT Applied Manual FR-F740P-220K-CHT Instruction manual. "MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 315KW.
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly used in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FR-F740P-220K-CHT Applied Manual FR-F740P-220K-CHT Instruction manual.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter FR-F740P-220K-CHT Applied Manual FR-F740P-220K-CHT Instruction manual. "
