MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 2.2KW.
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 MITSUBISHI FR-A7AP MITSUBISHI FR-A7AP FR-A7AP The output signal can open collector output inverter host standard.
Can be from the voltage output terminal (AM0), the current output terminal (AM1) output analog signal (output frequency, output current, etc.).
Can be connected to the 20mA DC or 10V DC meter MITSUBISHI FR-A7AP. "Applicable motor capacity: 0.4KW.
Rated current: 1.2A.
Power supply voltage: three phase 400V.
Frequency converter and GOT supporting the use, to achieve a higher price.
SIMPLE GOT series can be directly connected to the IS70 series inverter.
GOT can be directly connected with the inverter. After connecting the two, the communication parameters can be automatically set MITSUBISHI Frequency converter communication accessories.
In addition, the software can display the soft component of the control function in the GOT, even when the multi frequency converter is connected,
Can also be unified management with 1 GOT MITSUBISHI Frequency converter communication accessories.
Through the GOT screen to create software to import the picture data after the GOT,
Only use RS-422 connection GOT and frequency converter,
Can change the inverter speed / direction, monitoring the output frequency / output current and set a variety of parameters MITSUBISHI Frequency converter communication accessories. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.75KW.
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 to DC (DC), the process is called rectification FR-A7AP.
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 MITSUBISHI FR-A7AP.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
