下图为带动态惯量阻尼器的步进电机暂态特性的步进响应的比较。此种吸振阻尼器不会像反相制动方法那样，在产生超调后才制动，但也不会消除最初的超调量。此种动态惯量阻尼器可以改善步进电机高速区域的共振引起的转矩降低，也可以改善高速时的转矩和响应脉冲。利用驱动电路的改善半步进1-2相激磁的情况：阻尼以及定位时，利用2相激磁比1相激磁要好。所以两相步进电机使用半步进驱动的1-2相激磁时，停止相采用2相激磁，阻尼会变好。

跳跃闭锁继电器的电流启动值。电气防跳回路通常选用电流型动作线圈跳跃闭锁继电器，作为电流启动。根据电力工业部1984年反事故措施和电力系统二次回路设计规程规定，跳跃闭锁继电器的电流启动值应与断路器的跳闸电流配合，其电流启动值不得大于断路器跳闸电流的50%。也就是说跳跃闭锁继电器电流线圈动作值按断路器跳闸电流选择，以保证继电器的灵敏度。当断路器跳闸电流改变时，必须更换相应规格的跳跃闭锁继电器，这也就是为什么保护厂家继电器板子提供不同规格跳跃闭锁继电器启动电流的原因。
