From the definition of soft starting, requirements and harm of direct starting motor were pointed out; the working principle, control mode and technical characteristics of soft starting were introduced; combined with the application condition of soft start, calculating result proved that the starting voltage drop could meet the design requirements;the debugging process of soft start was introduced as well as the soft starting process of the synchronous motor. Common faults and treatment methods were listed, finally application effect was analyzed and the matters needing attention were put forward.
