5.4.4 Smoothing
Applying a filter to a reference pulse input, this function provides smooth servomotor operation in the follow-
ing cases.
• When the host controller that outputs a reference cannot perform acceleration/deceleration processing.
• When the reference pulse frequency is too low.
Note: This function does not affect the travel distance (i.e., the number of pulses).
(1) Related Parameters
Set the following filter-related parameters.
Change the setting while there is no reference pulse input and the servomotor stops.
∗ When set to 0, a filter becomes ineffective.
<Note>
The difference between the position reference acceleration/deceleration time constant (Pn216) and the position reference
movement averaging time (Pn217) is shown below.

While the motor is rotating, changes in Pn216 or Pn217 will not be reflected. The
changes will be effective after the motor comes to a stop with no reference pulse input.
