CXP-544A-KOMS-A2 KOKUSAI外設接口電路用于連接手持編程器或其他圖形編程器、文本顯示器，并能通過外設接口組成PLC的控制網(wǎng)絡。PLC使用PC/PPI電纜或者MPI卡通過RS-485接口與計算機連接，可以實現(xiàn)編程、監(jiān)控、聯(lián)網(wǎng)等功能。

CXP-544A-KOMS-A2 KOKUSAI系統(tǒng)程序由PLC制造廠商設計編寫，并存入PLC的系統(tǒng)存儲器中，用戶不能直接讀寫與更改。系統(tǒng)程序一般包括系統(tǒng)診斷程序、輸入處理程序、編譯程序、信息傳送程序及監(jiān)控程序等。

CXP-544A-KOMS-A2 KOKUSAI今天的綜合驅(qū)動包通常結(jié)合了幾種解決方案，以提供一個可靠和強大的系統(tǒng)。使用旁路內(nèi)置軟啟動器的驅(qū)動器具有一系列優(yōu)勢。一般來說，軟啟動器是為要求三相電機可靠有效軟啟動的客戶設計的。

使用軟啟動的優(yōu)勢包括:

最小化對機械部件的沖擊

延長系統(tǒng)的壽命

提高可靠性

減少停機時間

降低成本

CXP-544A-KOMS-A2

CXP-544A-KOMS-A2 KOKUSAI較低的浪涌電流對電氣元件和結(jié)造成的壓力較小，進一步延長了系統(tǒng)壽命。軟起動裝置減少了打滑、嘯叫和拉伸，并將皮帶壽命延長到傳統(tǒng)跨線起動器的2到6倍。減少對傳送帶和物料搬運設備上的產(chǎn)品的沖擊會降低與搬運產(chǎn)品的損壞相關的成本。在泵的應用中，軟啟動器能夠軟停止電機，從而減輕通常所說的水錘效應。
接觸器:只需將電機直接跨接在交流線上。連接到交流線路的電機會非常快地加速到全速，并在加速過程中消耗大量電流。
CXP-544A-KOMS-A2 KOKUSAI用于緩慢提升電機至全速，和/或緩慢降低電機至停止。為了降低電流消耗和系統(tǒng)的機械應變，使用軟啟動器代替接觸器。通過提供平穩(wěn)的負載加速和減速，軟啟動器能夠減少皮帶、齒輪、鏈條、離合器、軸和軸承的磨損。許多大型泵和風扇需要至少30秒的斜坡時間，以防止對系統(tǒng)造成機械損壞。通常，軟啟動器在大馬力系統(tǒng)中更常見。在負載突然停止可能導致系統(tǒng)或產(chǎn)品損壞的應用中，它們通常至關重要。
可調(diào)頻率驅(qū)動器:具有軟啟動器的斜坡能力，允許速度變化，并提供更多的靈活性和各種附加功能。
當用于不能承受停機時間的應用中時，封閉式變頻驅(qū)動器通常包括旁路。旁路配置由三個接觸器組成:一個接觸器將傳動與交流電源斷開，另一個將電機與傳動斷開，最后一個接觸器將電機直接連接到交流線路。看見圖1對于典型的三接觸器旁路配置。

The CXP-544A-KOMS-A2 KOKUSAI peripheral interface circuit is used to connect the handheld programmer or other graphic programmer, text display, and can form the PLC control network through the peripheral interface. PLC uses PC/PPI cable or MPI card to connect with the computer through the RS-485 interface, which can realize programming, monitoring, networking and other functions.

The program of the CTP-544A-KOMS-A2 KOKUSAI system is designed and written by the PLC manufacturer and stored in the PLC system memory, and the user can not directly read and write and change. System programs generally include system diagnostic programs, input processing programs, compilers, information transfer programs and monitoring programs.

CXP-544A-KOMS-A2 KOKUSAI Today’s comprehensive drive packages often combine several solutions to provide a reliable and powerful system. Drives that use bypass built-in soft starters have a number of advantages. In general, soft starters are designed for customers who require reliable and effective soft starting of three-phase motors.

Advantages of using a soft boot include:

Minimize impact on mechanical components

Extend system life

Improve reliability

Reduce downtime

Reduce cost

The lower inrush current of the CXP-544A-KOMS-A2 KOKUSAI causes less stress on the electrical components and junctions, further extending the system life. Soft starters reduce skidding, whistling, and stretching, and extend belt life to two to six times that of conventional cross-line starters. Reducing the impact on products on conveyor belts and material handling equipment reduces the costs associated with damage to moving products. In pump applications, the soft starter can soft stop the motor, thereby mitigating what is commonly referred to as the water hammer effect.
Contactor: Simply connect the motor directly to the AC line. A motor connected to an AC line accelerates to full speed very quickly and consumes a lot of current during acceleration.
The CVP-544A-KOMS-A2 KOKUSAI is used to slowly raise the motor to full speed, and/or slowly lower the motor to a stop. In order to reduce current consumption and mechanical strain on the system, a soft starter is used instead of a contactor. By providing smooth load acceleration and deceleration, soft starters reduce wear on belts, gears, chains, clutches, shafts and bearings. Many large pumps and fans require at least 30 seconds of ramp time to prevent mechanical damage to the system. In general, soft starters are more common in high-horsepower systems. They are often critical in applications where a sudden stop in load can lead to system or product damage.
Adjustable frequency driver: Has the ramp capability of a soft starter, allowing for speed variations and providing more flexibility and a variety of additional features.
When used in applications that cannot withstand downtime, enclosed variable frequency drivers typically include a bypass. The bypass configuration consists of three contactors: one that disconnects the drive from AC power, another that disconnects the motor from the drive, and a final contactor that connects the motor directly to the AC line. See Figure 1 for a typical three-contactor bypass configuration.
