For A6TBXE/A6TBY36E/A6TBX54E/A6TBY54E/A6TBX70E (common cathode; source) long 3m.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 FR-L740-3.7K-CHT
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 MITSUBISHI .
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. Servo motor series: low inertia, medium / high power.
Rated output: 1.5kw.
Rated speed: 3000r/min.
Electromagnetic brake: with.
Shaft end specification: Standard (straight axis).
Voltage: 400V level.
Features: low inertia for high speed / acceleration and deceleration operation occasions.
IP level: IP67.
Application example:
1, food processing machinery.
2, printing machine.
3, injection molding machine (11KW, 15KW).
4, large press machine (11KW, 15KW).
The protection level of the HF-SP/HF-JP series servo motor is IP67 (except the shaft part).
Low inertia of the power servo motor (0.5kW ~ 9kW), the maximum speed: 6000r/min (rated speed: 3000r/min),
Suitable for high frequency positioning and acceleration / deceleration operations, especially for food processing machines and printing machines.
Low inertia, high power, no cooling fan servo motor (11kW and 15kW), maximum speed: 3000r/min (rated speed: 1500r/min).
The motor structure is more compact due to the adoption of the non cooling fan design, andd the connection is reduced by uusing the power source connector MITSUBISHI FR-L740-3.7K-CHT.
(compared with the HF-LP series servo motor with the same power, the volume is reduced by about 46%, and the weight is reduced by about 34%,
Suitable for high frequency positioning annd acceleration / deceleration operations, especially for injection molding machines and large presses MITSUBISHI FR-L740-3.7K-CHT.
HF-JP703 (4) /903 (4) maximum speed: 5000r/min.
