CXP-544A-KOMS-A2 KOKUSAI外设接口电路用于连接手持编程器或其他图形编程器、文本显示器，并能通过外设接口组成PLC的控制网络。PLC使用PC/PPI电缆或者MPI卡通过RS-485接口与计算机连接，可以实现编程、监控、联网等功能。

CXP-544A-KOMS-A2 KOKUSAI系统程序由PLC制造厂商设计编写，并存入PLC的系统存储器中，用户不能直接读写与更改。系统程序一般包括系统诊断程序、输入处理程序、编译程序、信息传送程序及监控程序等。

CXP-544A-KOMS-A2 KOKUSAI今天的综合驱动包通常结合了几种解决方案，以提供一个可靠和强大的系统。使用旁路内置软启动器的驱动器具有一系列优势。一般来说，软启动器是为要求三相电机可靠有效软启动的客户设计的。

使用软启动的优势包括:

最小化对机械部件的冲击

延长系统的寿命

提高可靠性

减少停机时间

降低成本

CXP-544A-KOMS-A2 KOKUSAI较低的浪涌电流对电气元件和结造成的压力较小，进一步延长了系统寿命。软起动装置减少了打滑、啸叫和拉伸，并将皮带寿命延长到传统跨线起动器的2到6倍。减少对传送带和物料搬运设备上的产品的冲击会降低与搬运产品的损坏相关的成本。在泵的应用中，软启动器能够软停止电机，从而减轻通常所说的水锤效应。
接触器:只需将电机直接跨接在交流线上。连接到交流线路的电机会非常快地加速到全速，并在加速过程中消耗大量电流。
CXP-544A-KOMS-A2 KOKUSAI用于缓慢提升电机至全速，和/或缓慢降低电机至停止。为了降低电流消耗和系统的机械应变，使用软启动器代替接触器。通过提供平稳的负载加速和减速，软启动器能够减少皮带、齿轮、链条、离合器、轴和轴承的磨损。许多大型泵和风扇需要至少30秒的斜坡时间，以防止对系统造成机械损坏。通常，软启动器在大马力系统中更常见。在负载突然停止可能导致系统或产品损坏的应用中，它们通常至关重要。
可调频率驱动器:具有软启动器的斜坡能力，允许速度变化，并提供更多的灵活性和各种附加功能。
当用于不能承受停机时间的应用中时，封闭式变频驱动器通常包括旁路。旁路配置由三个接触器组成:一个接触器将传动与交流电源断开，另一个将电机与传动断开，最后一个接触器将电机直接连接到交流线路。看见图1对于典型的三接触器旁路配置。

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.
