MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 220KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment GT2310-VTBA.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit GT2310-VTBA
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on GT2310-VTBA. Three remote components can be connected to the CC-LINK system.
Remote I/O: refers to the field components that require only ON/OFF control,
Such as digital I/O or pneumatic valve, etc..
In this type of communication can only be carried out in the bit data GT2310-VTBA.
Remote components: the field components that require processing of register data,
For example analog I/O and counter, etc . .
In this type of component, in addition to the bit data can be carried out in the register data communication.
Intelligent remote: this type of element refers to the actions that allow the master station or other station to access,
To collect data and control the local PLC station,
GOTS and programmer interface unit are of this type.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
