  三、 加减速时间 
 加速时间就是输出频率从0上升到频率所需时间,减速时间是指从频率下降到0所需时间。通常用频率设定信号上升、下降来确定加减速时间。在电动机加速时须限制频率设定的上升率以防止过电流,减速时则限制下降率以防止过电压。
  加速时间设定要求:将加速电流限制在变频器过电流容量以下,不使过流失速而引起变频器跳闸;减速时间设定要点是:防止平滑电路电压过大,不使再生过压失速而使变频器跳闸。加减速时间可根据负载计算出来,但在调试中常采取按负载和经验先设定较长加减速时间,通过起、停电动机观察有无过电流、过电压报警;然后将加减速设定时间逐渐缩短,以运转中不发生报警为原则,重复操作几次,便可确定出佳加减速时间。
