Filter

General

Functional Description

Displays the filter value in ms.

The input value is rounded down internally to the next power of two. The reasonable maximum value depends on the parameter CycleTime.

CycleTime 1 ms -> maximum value 128

CycleTime 2 ms -> maximum value 256

CycleTime 4 ms -> maximum value 512

Example

Filter = 40 ms/ CycleTime = 2 ms

-> internal time constant of the filter = 32 ms

-> maximum value 256 was not reached

NOTE: The filter is a low-pass filter and affects the actual velocity. If the filter is set too high, it can lead to oscillation of the system depending on the velocity path. If you change the FeedConstant, Direction, and Filter parameters when the master encoder is running it leads to a continuous loss of position.
