MITSUBISHI 4KEROM

MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible 4KEROM.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used 4KEROM For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced 4KEROM.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Input points: 32 points.
Voltage: AC200 ~ 240V.
Current: 12mA.
Response time: 25ms.
32 points / a common end.
38 point terminal station.
CE certification.
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 4KEROM.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 executioon, the output refresh 4KEROM.
The coontents 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 thhe adoption of centralized sampling 4KEROM.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
