三菱通用伺服MELSERVO-J3系列是在MELSERVO-J2-Super系列基础上开发的性能更高、功能更丰富的交流伺服。
控制模式有位置控制、速度控制和转矩控制三种。还可以选择位置／速度切换控制，速度／转矩切换控制和转矩／位置切换控制。所以本伺服不但可以用于机床和普通工业机械的高精度定位和平滑的速度控制，还可以用于线控制和张力控制等，应用范围十分广泛。
此外，本产品有USB和RS-422串行通信功能，可以使用装有伺服设置软件的个人计算机，进行参数的设定、试运行、状态显示的监控和增益调整等。
本产品的实时自动调整功能可以根据机械自动调整伺服的增益。MELSERVO-J3系列伺服电机采用了分辨率为262144脉冲／转的绝对位置编码器，与MELSERVO-J2-Super系列相比，可以进行更高精度的控制。伺服放大器只需安装电池，就可以构成绝对位置检测系统。这样，只需进行一次原点设定，在电源开启和报警发生时就不再需要原点回归。
than 200 graphic symbols and an extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to complete the configuration and debugging of process level, operation level and even fieldbus instruments, and uses the same
a global database.
The scale of the system is highly scalable, and a single-system supports 1 to a maximum of 100 control stations and 100 operating stations. each control
The station can support several thousand I/0 points at most, and the scale of the whole system can be expanded. The hardware of the system control station is encapsulated in an all-metal shell, which can withstand the most
Harsh industrial environment. The device can be installed either in a cabinet or on a wall. System complies with all current EMC standards and is CE marked
Chi.
Industrial” DCS system design purpose: the most economical engineering investment, the most powerful control function.
Five features of Industria1″ DCS system:
1. All-round integrated control system, integrating DCS & PLC & Field Bus;
2. Using RISC SuperScalar high-speed CPU, with super performance;
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple engineering: configuration, commissioning and diagnostics using only the same tool CBF (Control Build F) software
mouth
Access to all information from the field including equipment management information
Global database of fieldbus devices, control levels and HMI (Human Machine Interface) usage systems
Module identification with production
