PSTX142-600-70軟驅動器引腳功能
PSTX142-600-70電動機屬感性負載，電流滯後電壓，大多數用電器都屬此類。為了提高功率因數須用容性負載來補償，並電容或用同步電動機補償。
PSTX142-600-70降低電動機的激磁電流也可提高功率因數(HPS2節能功能，在輕載時降低電壓，使激磁電流降低，使COS∮提高)。節能運行模式：輕載時降低電壓減少了激磁電流，電機電流分為有功分量和無功分量。
PSTX142-600-70節能運行模式：當電動機負載輕時，軟起動器在選擇節能功能的狀態下，PF開關熱撥至Y位，在電流反饋的作用下，正藝軟起動器自動降低電動機電壓。減少了電動機電 流的勵磁分量。
PSTX142-600-70從而提高了電動機的功率因數(COS∮)。(國產軟起動器多無此功能)在接觸器旁路狀態下無法實現此功能。TPF開關提供了節能功能的兩種反應時間；正常、慢速。節能運行模式：自動節能運行。正常、慢速兩種反應速度）空載節能40%，負載節能5%。
PSTX142-600-70The motor is an inductive load, and the current lags the voltage. Most electrical appliances fall into this category. In order to improve the power factor, capacitive loads must be used to compensate, and capacitors or synchronous motors must be used to compensate.
PSTX142-600-70Reducing the excitation current of the motor can also improve the power factor (HPS2 energy-saving function reduces the voltage at light load, reducing the excitation current and increasing COS∮). Energy-saving operation mode: reducing the voltage at light load reduces the excitation current, and the motor current is divided into active components and reactive components.
PSTX142-600-70Energy-saving operation mode: When the motor load is light and the soft starter selects the energy-saving function, the PF switch is hot-dialed to the Y position. Under the action of current feedback, the Zhengyi soft starter automatically reduces the motor voltage. The excitation component of the motor current is reduced.
PSTX142-600-70Thereby improving the power factor (COS∮) of the motor. (Most domestic soft starters do not have this function) This function cannot be realized when the contactor is in bypass state. The TPF switch provides two response times for the energy-saving function; normal and slow. Energy-saving operation mode: automatic energy-saving operation. Normal and slow response speeds) No-load energy saving 40%, load energy saving 5%.
