一般电机速度0到或从减到0，时间应控制在200ms以下，甚至小于几十毫秒且速度变化时不应有超调;另一方面，是当负载突变时，过度过程前言要陡，恢复时间要短，且无震荡，这样才能得到光滑的加工表面。
4、能在低速时输出大的转矩。
数控机床的进给系统常在相对较低的速度下进行切削，故要求伺服系统能够输出大的转矩。普通加工直径400mm的车床，纵向和横向的驱动力矩都在10Nm以上。为此，数控机床的进给传动链应尽量短，传动摩插系数尽量小，并减少间隙，提高刚度，减少惯量，提率。

nsk轴承安装：往轴上安装进口轴承前，必须先拔下轴承外套的固定销，同时将轴颈表面打磨光滑干净，并在轴颈处涂油防锈兼润滑(允许轴承在轴上有稍微转动)。在轴承座与轴承配合面涂润滑油，把轴承装入轴承座内。然后将装配好的轴承与NSK轴承座一起套在轴上.推至所需位置处进行安装。固定轴承座的螺栓先不要拧紧，要让轴承外套在轴承座内能转动。同样装好同一根轴上的另一端轴承和座，将轴转动几圈，让轴承本身自动找正位置后。

3）试方向
对于一个闭环控制系统，如果反馈信号的方向不正确，后果肯定是灾难性的。通过控制器打开伺服的使能信号。此时伺服电机应该以一个较低的速度转动，这就是所谓的“零漂”。一般控制器上都会有零漂的指令参数。使用这个指令或参数，看电机的转速和方向是否可以通过这个指令控制。如果不能控制，检查模拟量接续及控制方式的参数设置。确认给出正数，电机正转，编码器计数增加；给出负数，电机反转，编码器计数减小，如果电要带有负载，行程有限，不要采用这种方式。测试不要给过大的电压，建议在1V以下。如果方向不一致，可以修改控制器或电机上的参数，使其一致。
