"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 15KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification A951GOT-QLBD.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) A951GOT-QLBD
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter A951GOT-QLBD. "Output points: 16 points .
Voltage: DC24V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 2ms.
8 points / a common end.
20 point terminal station.
With short circuit protection.
With the surge absorber.
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 A951GOT-QLBD.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
UUnder the premise of meeeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A951GOT-QLBD.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A951GOT-QLBD.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
