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 Q62DA-FG Self service (IN, OUT): SI optical cable.
Other aspects (IN, OUT): SI optical cable.

Analog touch panel.
Do not let the touch screen surface with water drops or other soft things stick to the surface,
Otherwise, the touch screen is easy to mistake that there is a hand touch caused by surface acoustic wave screen is not allowed.
In addition to cleaning the dirt on the surface of the touch screen,
You can use a soft dry cloth or a cleaning agent to clean out the center of the screen carefully,
Or use a dry soft cloth dipped in industrial alcohol or glass cleaning fluid to clean the touch screen surface.
Touch screen response is slow if you use a hand or other touch to touch the surface acoustic wave touch screen,
This shows that it is likely that the touch screen system has been obsolete, the internal clock frequency is too low,
Or because there is water in the surface of the touch screen to make the touch screen mobile, rapid response recovery,,
To replace or upgrade the system must, or use dry cloth touch screen on the surface of the water Q62DA-FG.
If the user is operating the touch screen, the direction of the touch move is to the left,
But the cursor of the system moves to the right,
The failure may be due to the conneecttion of the control box and the touch screen connected to the connector or the touch screen,
Users as long as the direction of the re exchange of it Q62DA-FG.
