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 .
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 FX2N-64DP-M
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action FX2N-64DP-M.
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 FX2N-64DP-M.
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. Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 3.0kw.
Rated speed: 1000rpm.
With the brake: without.
Shaft end: straight shaft.
The structure of the ACC servo motor stator is bbasically similar to the capacitor split phase single-phase induction motor FX2N-64DP-M.
The stator is provided with two positions of 90 degrees of mutual difference of the winding, one is the excitation winding Rf, it is always connected to the AC voltage Uf;;
TThe other is to control the winding L, which is connected to the control signal voltage Uc FX2N-64DP-M.
So the AC servo motor, also known as the two servo motor.
