5.1.7 Acceleration/Deceleration Filter Settings
There are two types of acceleration/deceleration filter: The exponential acceleration/deceleration filter and the mov-
ing average filter. These filter settings can be used to set non-linear acceleration/deceleration curves. The parameters
related to the acceleration/deceleration filter settings are listed in the following table.
The following figure shows the relationship between acceleration/deceleration patterns and each parameter.

Bits 8 to B
Filter Type
Selection
Set the acceleration/deceleration filter type.
0: None
1: Exponential acceleration/deceleration filter
2: Moving average filter
The Change Filter Type command (OW 08 = 13)
must be executed in advance to enable the Filter
Type.
0
OW 3A
Filter Time
Constant
Sets the acceleration/deceleration filter time constant.
Always make sure that pulse distribution has been com-
pleted (i.e., that monitoring parameter IW
0C, bit 0 is
ON (1)) before changing the time constant.
