(3)重载下降时，原拖动系统的电动机从接法上说，是正方向的，产生的转矩也是正的。但由于在转子电路中串入了大量电阻，使机械特性倾斜至如曲线⑤所示。这时，电动机产生的正转矩比重力产生的转矩小，

非但不能带动重物上升，反而由于重物的拖动，电动机的实际旋转方向是负的，其工作点在机械特性向第四象限的延伸线上，如图中E点所示，这时，转速为n5。这种工作状态的特点是：电动机的转矩是正的、却被重物“倒拉”着反转。解决这种现象的途径只能是选择较大的功率，这无形便增加了设备成本。
与变频调速方式（如图5所示）相比较，在重载下降时，两种调速方法的工作点都在第四象限，但电动机的工作状态是不同的。３　采用变频调速需要注意的问题
(1)重物起吊时起动转矩Ts较大，通常在额定转矩 TN的150％以上。考虑到在实际工作中可能发生的电源电压下降以及短时过载等因素，一般情况下，起动转矩 Ts应按照额定转矩TN的150％～180％来进行选择：
Ts = ( 150% ~ 180 % ) TN (4)
(2)起升机构工作过程中，在重物刚离开泊位上升的瞬间以及在重物刚到达新泊位下降的瞬间，负载转矩的变化是十分激烈的，应引起注意。
(3)起升装置在调整缆绳松弛度时，以及移动装置在进行定位控制时，都需要点动运行，应充分注意点动时的工作特性。
