NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
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 MITSUBISHI .
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 QC05B
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action MITSUBISHI .
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 MITSUBISHI .
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. MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 30.0kw.
Universal interface.
Voltage: 3 phase AC400V.
Super function, excellent performance.
High performance CPU integration, greatly improve product responsiveness.
Due to the application of high performance CPU, so that the response can be greatly improved.
Speed loop frequency response increased to more than 550HZ.
MR-J2-Super series is the best device for high speed positioning applications.
Easy adjustment.
Model adaptive control / advanced reall time automatic tuniing MITSUBISHI QC05B.
Mechanical analysis function.
Can analysis of the frequency characteristics of the mechanical system, the results can be easily set up "mechanical resonance suppression filter"
Mechanical simulation function.
The function ccann be realized without the actual replacement of the motor MITSUBISHI QC05B. Read mechanical analysis results to simulate the response of the user''s mechanical system.
