【文章內容簡介】 ly is arrives 34KHz, but the highest movement frequency may achieve N*102 KHz. Surpasses the highest starting frequency the frequency directon starting, will appear\ Falls out of step \ Phenomenon, even is unable to start. The more ideal starting curve should be according to the index rule starting. But the practical application to starts the section processing to be possible to use according to the fitting a straight Line method, namely \ Steps and ladders law \”. May according to two kind of situations processing, (1) known frequency press the frequency partition to start, the partition counts n=f/f q. (2) Unknown frequency, then to assigns according to the section. Uses \ Steps and ladders law \ Continuously raises the speed the speed which needs, then locking, according to preplaced curve movement. Fitting the starting frequency, after each section of frequencies hand over the increase (to call steps and ladders frequency) △ f=f/8, namely uses 8 sections of fitting. In the operating control process, (frequency) divides into the outset speed n minute achievement steps and ladders frequency, When steps of machine mutation questions step of machine mutation, certainly must stop in the electrical machinery or fall mutates again to the frequency range in, in order to avoid has a bigger impact to damage the electrical machinery. The mutation signal certainly must last the CP pulse finish after the preceding direction as well as in front of the next direction first CP pulse sends out. steps of machine mutation questions Step of machine mutation, certainly must stop in the electrical machinery or fall mutates again to the frequency range in, in order to avoid has a bigger impact to damage the electrical machinery. The mutation signal certainly must last the CP pulse finish after the pr
