、失速防止功能是什么意思？
如果给定的加速时间过短，变频器的输出频率变化远远.过转速（电角频率）的变化，
变频器将因流过过电流而跳闸，运转停止，这就叫作失速。
为了防止失速使电机继续运转，就要检出电流的大小进行频率控制。
当加速电流过大时适当放慢加速速率。减速时也是如此。两者结合起来就是失速功能。
、有加速时间与减速时间可以分别给定的机种，和加减速时间共同给定的机种，这有什么意义？
加减速可以分别给定的机种，对于短时间加速、缓慢减速场合，
或者对于小型机床需要严格给定生产节拍时间的场合是适宜的，
但对于风机传动等场合，加减速时间都较长，加速时间和减速时间可以共同给定。
、什么是再生制动？
电动机在运转中如果降低指令频率，则电动机变为异步发电机状态运行，
作为制动器而工作，这就叫作再生（电气）制动。
、是否能得到更大的制动力？
从电机再生出来的能量贮积在变频器的滤波电容器中，
由于电容器的容量和耐压的关系，通用变频器的再生制动力约为额定转矩的10%~20%。
如采用选用件制动单元，可以达到50%~100%。
