MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 5.5kw.
SLD converter rated current: 12.6A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed MITSUBISHI MR-J3-11KB-RJ004.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption MR-J3-11KB-RJ004
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor MITSUBISHI MR-J3-11KB-RJ004.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control . Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line function (GI cable) MITSUBISHI MR-J3-11KB-RJ004.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage cappacity: it is a measuure of how much the user application can store the number of indicators MR-J3-11KB-RJ004.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General lloggical operation instructions each account for 1 words MR-J3-11KB-RJ004. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
