接觸器:只需將電機(jī)直接跨接在交流線上。連接到交流線路的電機(jī)會(huì)非常快地加速到全速，并在加速過(guò)程中消耗大量電流。
CXP-544A-KOMS-A2 KOKUSAI用于緩慢提升電機(jī)至全速，和/或緩慢降低電機(jī)至停止。為了降低電流消耗和系統(tǒng)的機(jī)械應(yīng)變，使用軟啟動(dòng)器代替接觸器。通過(guò)提供平穩(wěn)的負(fù)載加速和減速，軟啟動(dòng)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(fēng)扇需要至少30秒的斜坡時(shí)間，以防止對(duì)系統(tǒng)造成機(jī)械損壞。通常，軟啟動(dòng)器在大馬力系統(tǒng)中更常見(jiàn)。在負(fù)載突然停止可能導(dǎo)致系統(tǒng)或產(chǎn)品損壞的應(yīng)用中，它們通常至關(guān)重要。

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.
