Calculation of Basic Acceleration/Deceleration Times

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.
Sequence #n
Completion code:
continuous
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."
If the acceleration/deceleration time designation is set to 0 in sequence data
used for memory operation, the acceleration time is the time it takes to reach
the maximum speed from the initial speed (which is also set in the axis param-
eter area). Similarly, the deceleration time is the time it takes to go from the
maximum speed to the initial speed. If the acceleration/deceleration time des-
ignation is set to 1, the acceleration or deceleration time is directly set as the
time from the present speed to the target speed.
This section describes the acceleration/deceleration time when operation is
performed using a speed command specified for memory operation with the
acceleration/deceleration time designation set to 0.
