3. Position reference lter
The input position references are ltered to make rotation of the servo motor smoother. This
function has obvious effects in the following scenarios:
•
Acceleration/deceleration processing is not performed on the reference pulses output by
the host controller and the acceleration/deceleration rate is large.
•
The pulse frequency is too low.
•
The electronic gear ratio is larger than 10.
This function has no effect on the displacement (total pulses of position references).
The parameter setting for the position reference lter is as follows:
