MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1.5KW.
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 GT05-50PCO "Series introduction: with a variety of advanced features of the compact model.
Screen size: 5.7 inches.
Display color: 256 color or more color.
Mounting type: panel mounting type.
Resolution: QVGA (320 x 240).
Display device: STN monochrome.
Host frame color: black.
Power type: DC24V.
Communication interface: QnA/ACPU/ for CPU motion controller (A) built-in bus connection interface.
The first characteristic of touch screen:
Transparent, it directly affects the visual effect of touch screen.
The problem of transparency is the degree of transparency, infrared technology, touch screen and surface acoustic wave touch screen is separated by a layer of pure glass,
Transparency can be considered a leader, the other touch screen this is a good scrutiny, transparency",
The touch screen industry, is a very broad concept, many touch screen is a multilayer composite film,
It''s not enough to generalize its visual effect with only a little transparency,
It should include at least four characteristics: transparency, color distortion, reflection and clarity, but also,
For example, the degree of reflection, including the degree of specular reflection and diffraction,
But the touch screen surface diffraction reflection has not reached the extent of the CD disk,
For users, these four metrics are basically enough. "
