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%) FX3GE-24MT/ES Basic & Applied Instructions Edition Manual FX3GE-24MT/ES PROGRAMMING MANUAL FX3GE-24MT/ES
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
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 FX3GE-24MT/ES Basic & Applied Instructions Edition Manual FX3GE-24MT/ES PROGRAMMING MANUAL. 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 FX3GE-24MT/ES Basic & Applied Instructions Edition Manual FX3GE-24MT/ES PROGRAMMING MANUAL. Max input / output points: 14 points.

Its MT series of PLC can drive 2 way servo or stepper, commonly used in the control system for a simple manipulator.
MITSUBISHI FX1S series PLC is suitable for the smmallest package,
It is the preferred target for low cost users to seek powerful control over a limited range of I/0 FX3GE-24MT/ES Basic & Applied Instructions Edition Manual FX3GE-24MT/ES PROGRAMMING MANUAL.
FX1S provides up to 30 I/O points, and caan be transmitted through serial communication data,
MT models also have the ability to locate, widely used in a variety of small mechanical equipment FX3GE-24MT/ES Basic & Applied Instructions Edition Manual FX3GE-24MT/ES PROGRAMMING MANUAL.
