三菱 FR A700系列变频器功能说明书（卷取控制功能）（中文）
为了用于收/放卷机械，本功能说明书中对FREQROL-A700系列标准变频器添加了下述专用规格。
对于使用浮动辊的收卷机械，如果卷径比的范围取得比较宽，或者要提高进给速度等，本产品是有效的。最适合用于拉线机和印刷机的纸收卷等用途。
(1) 浮动辊控制功能
(2) 卷径补偿功能
浮动辊控制功能和卷径修正功能在V/F控制、先进磁通矢量控制、无传感器矢量控制（速度控制）和矢量控制（速度控制）中有效。
FR-A740-0.4K～500K-CA1
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
