MITSUBISHI QJ71LP21-25

3C-2V/5C-2V coaxial cable single bus remote I/O network (remote I/O station).
Q mode.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program MITSUBISHI .
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register QJ71LP21-25
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive MITSUBISHI .
Semiconductor circuit with memory function .
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear MITSUBISHI .
User memory: user program storage area and work data storage area .
Composed of random access memory (RAM). User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years. Power: 280kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function. Motor series: low inertia, small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 0.05kw.
Rated speed: 3000rpm.
With the brake: without.
Shaft end: straight shaft.
AC servo motor and brushless DC servo motor in the function of the difference: AC servo is better, because it is a sine wave control, torque ripple small.
DC servo is a trapezoidal wave. DC servo is simple and cheap. Motor: HA-LH type.
Power: 22kw.
Speed: 2000r/min.
According to the types of power supply: can be divided into DC motor and AC motor.
The structure and workking principle of DC motor can be divided into four parts: brushless DC motor and brushless DC motor MITSUBISHI QJ71LP21-25.
Brushless DC motor can be divided into: permanent magnet DC motor and DC motor.
DC Motor Division: Series DC motor, DC motor, DC motor and DC motoor MITSUBISHI QJ71LP21-25.
Permanent magnet DC Motor Division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel Gu Yongci DC motor.
