at least 3 sequences before, these changes will not be reflected in operation.
8-9 Acceleration/Deceleration
If the acceleration/deceleration time designation parameter in the axis param-
eter area is set to 0, the acceleration time specified in the sequence data for
memory operation will be the time required to go from the initial speed set in
the axis parameter area to the maximum speed and the deceleration time will
be the time required to go from the maximum speed to the initial speed. If the
acceleration/deceleration time designation parameter in the axis parameter
area is set to 1, the acceleration and deceleration times will be the times
required to go from the present speed to the target speed.
The following is an explanation of the acceleration and deceleration times
when speed commands are executed for memory operation with the accelera-
tion/deceleration time designation parameter in the axis parameter area set to
0.
If changes to the data used for
positioning sequence #n+3 are
made during this period, positioning
sequence #n+3 will be executed
according to the new settings.

Time
When positioning sequences with completion code set
to continuous are executed continuously, the PCU
reads the data for up to 3 sequences in advance. After
the pulse output for the first sequence has stopped
(i.e., when the next sequence starts), the data for
positioning sequence n+3 (in this case) is read.

If the speed used for positioning
sequence #n+3 is changed, the
speed will change in the way
shown at "A."
