MITSUBISHI FR-A720-2.2K PLC FUNCTION PROGRAMMING MANUAL PDF

Convert connectors to fast connectors.
According to the location of the connection equipment distribution module. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V FR-A720-2.2K PDF.
Frequency converter capacity: 560KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-A720-2.2K
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FR-A720-2.2K PDF.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity FR-A720-2.2K PDF. Power: 22kw.
Purpose: to suuppress the power harmonics FR-A720-2.2K Manual.
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 MITSUBISHI PLC FUNCTION PROGRAMMING 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 MITSUBISHI PLC FUNCTION PROGRAMMING MANUAL. ) MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.4KW.
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 (IIm1 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 PLC FUNCTION PROGRAMMING MANUAL FR-A720-2 FR-A720-2.2K PLC FUNCTION PROGRAMMING MANUAL. 2K Manual.
