变频器内的电子热保护功能,是用来作电动机过载保护的。这里简介它的功能特点和使用原则,供初次使用变频器的读者参考。 1.特点 (1)电子热保护功能并不能直接检测电动机的温度,而是综合与温度有关的参数值来判断电动机是否处于过热状态。这些参数是: ①工作电流。它是电动机发
The electronic thermal protection in the inverter is used for motor overload protection. Here is a brief introduction of its features and principles of use for the first time using the inverter reader reference. 1. Features (1) The electronic thermal protection function does not directly detect the temperature of the motor. Instead, it integrates temperature-related parameter values to determine whether the motor is overheated. These parameters are: ① working current. It is a motor hair
