Acceleration/Deceleration Filter Settings

There are two types of acceleration/deceleration filters: an exponential acceleration/decelera-
tion filter and an average movement filter. These filter settings can be used to set non-linear
acceleration/deceleration curves.
Related Parameters
The parameters that are related to acceleration/deceleration filter settings are listed in the fol-

This parameter sets the acceleration/deceleration
filter type.
0: No filter (Filter none)
1: Exponential acceleration/deceleration filter
2: Average movement filter
The Change Filter Type (CHG_FILTER) motion
command must be executed to enable the setting
of the Filter Type Selection parameter (i.e.,

OW 08 must be set to 13).
This parameter sets the acceleration/deceleration
filter time constant.
Always make sure that distribution has been com-
pleted (i.e., that bit 0 in IW
you change the filter time constant.
