MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-E520-2 FR-E520-2 FR-E520-2.2K2K Manual FR-E520-2.2K INSTRUCTION MANUAL. 2K Manual FR-E520-2.2K INSTRUCTION MANUAL. Power: 45kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-E520-2.2K Manual FR-E520-2.2K INSTRUCTION MANUAL.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Series Name: F920GOT with buttons, with a series of effective functional modules.

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.
The man-machine interface is the central linkk 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 engineeriing,
Safety management engineering and safety systems engineering to study the specific solutions and measures of the safety of human computer science FR-E520-2 FR-E520-2.2K Manual FR-E520-2.2K INSTRUCTION MANUAL. 2K Manual FR-E520-2.2K INSTRUCTION MANUAL.
