一個(gè)庫存全新的fx1s30mt用drvi指令頻率1000以下沒(méi)有變化調不下來(lái).2000.步進(jìn)電機就專(zhuān)叫不轉了..用plsy指今正常工作...


后來(lái)二手淘了個(gè)30mt.收到后發(fā)現是假的.把程序寫(xiě)入.drvi指今完全正�？刂祁l率.....為什么這樣的...???


庫存的拆開(kāi)看做工一點(diǎn)不假...二手的拆不開(kāi).但看線(xiàn)路板完全不一樣做工很差電阻電容手工焊的.

假冒的很好.怎么會(huì )這樣的????怎么會(huì )這樣的????

2個(gè)假冒???
