Motion Parameters
( 24 ) Acceleration/Deceleration Settings
The following two methods can be used to specify the acceleration/deceleration speed.
1. Setting the acceleration/deceleration speed
Set the speed within the range from 0 to 2147483647 reference units/s 2 .
When 0 or a negative value is set, the setting parameter warning will be generated and the axis will move at the
minimum acceleration or minimum deceleration speed.
2.
Setting the time to reach the rated speed from zero speed.
Set the time within the range from 0 to 32767 ms.
When a negative value is set, the setting parameter warning will be generated and the axis will move as it does
when 0 is set.
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.
OL 36
Straight Line Acceleration/Acceleration
Time Constant
Setting Range Setting Unit Default Value
0 to 2 31 −1
Depends on the acceleration/
deceleration unit set in Function
Setting 1 (setting parameter
OW 03, bits 4 to 7).
0
Description
Set the linear acceleration rate or linear acceleration time constant.
The setting unit for this parameter depends on the Acceleration/Deceleration Degree Unit Selection
(OW
03, bits 4 to 7), but the result of applying the acceleration/deceleration unit setting is not shown
here.
OL 38
Straight Line Deceleration/Deceleration
Time Constant
Setting Range Setting Unit Default Value
0 to 2 31 −1
Depends on the acceleration/
deceleration unit set in Function
Setting 1 (setting parameter
OW 03, bits 4 to 7).
0
Description
Set the linear deceleration rate or linear deceleration time constant.
The setting unit for this parameter depends on the Acceleration/Deceleration Degree Unit Selection
(OW
03, bits 4 to 7), but the result of applying the acceleration/deceleration unit setting is not shown
here.
