MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 355KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment FX1S-20MT-D.
The converter is composed of rectifier (AC), ffilter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on FX1S-20MT-D FX1S-20MT-D. 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 MITSUBISHI FX1S-20MT-D MITSUBISHI FX1S-20MT-D MITSUBISHI FX1S-20MT-D.

Positioning and pulse output functions: a PLC cell can output 2 point 100KHz pulses at the same time.
PLC is equipped with 7 special positioning instructions,
Including zero return, absolute or relative address expression and special pulse output control.
Host has 10 points (6I/4O), 14 points (8I/6O), 20 points (12I/8O), 30 points (16I/14O) of 4 types.
This type of PLC is mainly used in all of the digital input, digital output control point of the device.
Can be directly connected to the 220V city power, built-in 8K step EEPROM memory, no battery, easy to maintain.
The series transistor output (MT) of the PLC, can be output 2 100KHz pulse, direct drive servo or stepper motor.<
The series PLC can not be brought with the expansion module, but can be installed by the BD board to extend a small amount of I/O FX1S-20MT-D.
The series 1N through the installation of BD series PLC board, can achieve RS232, RS485, RS422 communication.
