伺服系统 插值器 interpolator

伺服系统中的插值器，用于在慢速控制周期和快速控制周期之间，使变量平滑

The switched on interpolator causes a finer grading of the speed setpoints from the ramp-function generator by calculating intermediate steps (interpolation).

Setpoint channel and PROFIBUS run in a slower time slice. The interpolator is used to linear interpolate the setpoints in the grid of the speed controller cycle. This avoids strong excitations caused by large steps in the speed setpoint.

通过计算中间步数（插值），插值器可使斜坡功能发生器的速度设定点更精细。

设定点通道和 PROFIBUS 在较慢的时间片中运行。插值器用于线性插值速度控制器周期网格中的设定点。这样可以避免速度设定点中的大步数引起的强烈震荡。
