软启动器参数的设置要根据不同的负载来设置，并选择合适的启动方式。不同的模式参数设置都不一样。
The setting of the soft starter parameters should be set according to the different loads and select the appropriate starting mode. Different schema parameters are different.
应根据负载的特性选择合适的启动模式。
(1) the appropriate startup mode should be selected according to the characteristics of the load.
为保证电机的软启动效果，斜坡初始电压不可设置过高，一般情况下设置为25%~50%范围内。
In order to ensure the soft start effect of the motor, the initial voltage of the slope can not be set too high. In general, it is set in the range of 25%~50%.
电压的百分比是指即时引入电网电压的百分比。
The percentage of the voltage is the percentage of the electric grid voltage that is introduced immediately.
电流的百分比是指当前额定电流的百分比。
The percentage of the current is the percentage of the current rated current.
当启停控制方式被设置为3，而外控连接为两线控制方式时，键盘启动和停止无效。
When the start and stop control mode is set to 3, while the external control connection is the two line control mode, the keyboard start and stop is invalid.
一般软启动器的设置分为：启动模式的设置，电压斜坡启动模式下的参数设置，限流启动模式下的参数设置，点动工作模式下的参数设置，控制方式的设置，额定输出电流调整设置，显示电流的校准等。
General soft starter set is divided into: start mode settings, set the parameters of the voltage slope start mode, limiting parameters of start mode settings, set the parameters of dynamic mode, control mode set, rated output current adjustment settings, display current calibration etc..
软启动器是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的新颖电机控制装置，国外称为Soft Starter。它的主要构成是串接于电源与被控电机之间的三相反并联闸管及其电子控制电路。运用不同的方法，控制三相反并联闸管的导通角，使被控电机的输入电压按不同的要求而变化，就可实现不同的功能。
Soft starter is a new motor control device which integrates motor soft start, soft parking, light load, energy saving and multiple protection functions. It is called Soft Starter abroad. It is mainly composed of three phase anti parallel thyristor and electronic control circuit connected to the power supply and the controlled motor. Different methods are used to control the conduction angle of three phase anti parallel thyristor, so that the input voltage of the controlled motor varies according to different requirements, and different functions can be achieved.
