Function extension board for RS-485 communication.
No DC24V consumption, no occupancy of the input output (FX1S and FX1N of the host computer). MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 7.5KW.
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 FX3G-60MR/ES-A USER'S MANUAL MITSUBISHI FX3G-60MR/ES-A USER'S MANUAL FX3G-60MR/ES-A Input and output points: 10 points.

A new application model.
FX3SA is a basic model on the basis of the basic performance of FX1S above the expansion of the expansion of the new model.
FX3SA is applicable to all kinds of fields of small scale equipment which need to simulate the quantity and function of MODBUS and Ethernet.
Basic models suitable for small scale control.
Compact but powerful,
At the same time, the analog quantity and communication function, etc.. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the raated current, therefore, the impact on the mechanical and electrical FX3G-60MR/ES-A Manual.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120%% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FX3G-60MR/ES-A Manual.
