Long distance bus connection for QCPU.
Applicable models: GT16, GT15, GT11, GT27, GT25. Data communication line module (optical cable) Master / local station for A3VTS multiplex system
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures MR-J4-60B-RJ010
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations. MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 7.0kw.
Interface type: SSCNET type III fiber communication.
Full closed loop control.
Power specification: three phase AC200V.
High precision and high response location control.
Full closed loop control can be realized by double feedback control method.
Dual feedback control can be performed between the servo motor encoder and the load side encoder.
MR-J3-B-RJ006 can be used in conjunction with a number of manufacturers of linear encoder,
Users can build the system according to their own accuracy requirements. ABS type linear encoder using serial interface,
No need to install the battery on the servo amplifier can easily build the absolute position detection system.
Flexible system configuration.
Can achieve higher load side positioning accuracy!A3VTS using the basic unit.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
The following describes the centralized control system I/O points of the estimate.
