MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
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.

It can respond quickly to the change of production line speed and avoid the phenomenon of uneven winding.
This helps to achieve a stable supply of high quality products. The frequency of a transducer can be set by a digital signal from an external BCD or binary code.
BCD code 3 (maximum 999).
BCD code 4 (maximum 9999).
Binary code 12 (max FFFH).
Binary code 16 (max FFFFH). "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 5.5KW.
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 device is the first power of the AC power conversion tto DC (DC), the process is called rectification FR-D720-0.75K.
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 fixeed frequency and a certain voltage of the inverter FR-D720-0.75K.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
