4.4.2 Motion Setting Parameter Details
4-50
( 23 ) 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 of 0 to 2147483647 reference units/s
2 .
When a negative value is set, the setting parameter warning will be generated and the axis will move at the max-
imum acceleration or maximum deceleration speed.
2.
Setting the time to reach the rated speed from zero speed.
Set the time within the range of 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.
When a value larger than 32767 is set, the setting parameter warning will be generated and the axis will move as
it does when 32767 is set.
For details on each acceleration/deceleration parameter, refer to 5.1.6 Acceleration/Deceleration Settings and 5.1.7
Acceleration/Deceleration Filter Settings.

Description
Set the linear acceleration rate or linear acceleration time constant.
The actual machine operation depends on the settings in the SERVOPACK parameters. Refer to 11.6 Parameters That Are
Automatically Updated for information on user constants self-writing function.
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 units setting is not shown
here.
