摘 要:在變頻器的運行模式中,外部運行模式是應用最廣泛的運行模式。在外部運行模式下,頻率給定方式有模擬量給定和數字量給定兩種,其中數字量給定可以獲得較高的頻率精度、模擬量給定可以實現電機的無級調速。
關鍵詞:外部運行模式;頻率給定;模擬量給定;數字量給定
Abstract: In the operation mode of inverter, external operating mode is the most widely used operating mode. In external mode, there are two kinds of analog and digital given in the frequency given mode, in which the digital given
