求助，由于對(duì)HLP--B變頻器不熟，特此請(qǐng)教。       變頻器帶電動(dòng)機(jī)正傳-----遇到工件-----停------電機(jī)反 轉(zhuǎn)  -----把工件拉回來(lái)-----再遇阻力再正轉(zhuǎn)，此過(guò)沒有感應(yīng)器，實(shí)現(xiàn)自動(dòng)正反轉(zhuǎn)。不知如何實(shí)現(xiàn)的？                                                                                                                                                                                                                                                                                                                                                

轉(zhuǎn)矩模式，扭矩達(dá)到一定值后換相？
