原系统电机是185kW的6极绕线式电机，在平时工作电流在280-380A，为保证安全，提升机上行或下行起动时，是要加制动的，起动完成后一瞬间再松开制动。在这种情况下运行电流有时候会超过电机额定电流，达到400多安培。变频调速后，提升机上行或下行起动时，仍是要加制动的，变频器输出频率到0.3Hz有足够大的力矩时再松开制动。尽管0.3Hz以下电机处于堵转状态，但由于输出频率低，输出电压也低，电机不会过流。在生产中，装载的物料有时可能会超载，考虑重载加速时间短，选型时变频器容量需要加大，本例变频器为280kW，这样有利于电机在过载时候变频器有足够的过载能力。
原有提升机系统的改造按以下几个步骤进行：
（1）变频系统操作时和原来工频系统在设备状态上有所不同，在提升机控制台上有个凸轮控制器，（其作用是利用控制器的多接点当作提升机的档位控制接触器，调节转子电阻的阻值大小，对应低高速档。）除开油路部分的控制触点以外的所有接点弹簧全部已被去掉，这样有利于在使用角位控制时候减少操作阻力。
（2）再将绕线式电机的转子绕组全部短接。
（3）利用原来的凸轮控制器，在凸轮控制器的后方轴上安装自整角机，与凸轮控制器的中心轴同心，这样利用原来上升和下放的操作模式。对应凸轮控制器的正负角度，分别角度是108°和-108°，自整角机把这个角位信号以脉冲形式送给角位变送器，角位变送器再根据正负角度对应输出+108°与-108°时的+10V和-10V的模拟电压信号，变频器接收±10V作为正反转运行信号。
（4）利用原凸轮控制器控制制动油路系统，在凸轮控制器上中心点到相对应两边第一个触头须使用。度过两边的触点后，随着操纵杆的推动平滑地过渡到±108°。在操纵杆未打到油路系统触点时，自整角机已经识别到角位的变化，对应角位变送器就会有正负电压的输出，因为在油路系统未打开之前变频器是有很低的频率输出（0～0.3Hz）。油路未打开刹车系统就处于制动状态，通过变频器内部的逻辑单元、算术单元和比较器等相关功能进行设置，过渡了两个接触点的清零位置，使得在操纵杆在过油路触点时候变频器在0.2Hz以下运行，得到非常好的控制效果。
