在闭环参数中可以选择的插补方式，这个插补方式到底怎么理解？
看到technology手册中的解释
Fine Interpolator
The fine interpolator function is used is to generate interim setpoints when the interpolator
and controller have a different duty factor. Optional interpolation mode settings at the fine
interpolator:
● No interpolation
● Linear interpolation (constant position for positioning axis)
● Interpolation with constant acceleration (constant acceleration at positioning axis)
● Interpolation with constant velocity (constant velocity at positioning axis)
When set for positioning axes, the position setpoint is interpolated.
When set as speed-controlled axis, the velocity setpoint is interpolated.
读了好多遍，就是理解不了什么意思？高手们能否给解释一下，非常感谢

插补是那两个变量的插补，为什么要用插补。
