5.4.2 Motion Setting Parameter Details
( 25 ) Filter
OW3A
Filter Time Constant
Set the acceleration/deceleration filter time constant.
Always make sure that pulse distribution has been completed (i.e., that monitoring parameter IW0C, bit 0 is ON)
before changing the time constant.
First, select the filter type by using the parameter Filter Type Selection (OW03, bits 8 to B), and then change the filter
Description
time constant.
Once the filter type is set using the motion command, the setting is held until the power is turned OFF or the filter type is
changed.
OW3B
Bias Speed for Index Acceleration/Deceleration Filter
Set the bias speed for the exponential acceleration/deceleration filter.
Description
 There are two types of acceleration/deceleration filter: an exponential acceleration/deceleration filter and a moving
average filter.
 For details on each acceleration/deceleration parameter, refer to 6.1.6 Acceleration/Deceleration Settings on page
6-11 and 6.1.7 Acceleration/Deceleration Filter Settings on page 6-13.

 The setting unit for this parameter depends on the Speed Unit Selection (OW03, bits 0 to 3), but the
result of applying the speed unit setting is not shown here.
