MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.1KW.
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-F720P-110K BASIC Manual FR-F720P-110K Instruction manual FR-F720P-110K BASIC Manual FR-F720P-110K Instruction manual FR-F720P-110K Input and output points: 10 points.

A new application model.
FX3SA is a basic model on the basis of the basic performance of the FX1S increased the expansion of the new models.
FX3SA is suitable for all kinds of fields, such as analog quantity, Ethernet, MODBUS function, small scale equipment and so on.
Basic models suitable for small scale control.
Compact but powerful,
At the same time, the analog quantity and the communication function and so on. Power: 0.4kw.
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 (755K) and above capacity and above capacity FR-F720P-110K BASIC Manual FR-F720P-110K 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 motorr power used to select the DC reactor FR-F720P-110K BASIC Manual FR-F720P-110K Instruction manual.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
