* Refer to section "5.7 List of control data" for details on the setting details.
(d) If the "new acceleration/deceleration time" is set to "0" and the speed is
changed after the "new acceleration/deceleration time" is validated, the
operation will be controlled with the previous "new acceleration/deceleration
time".

Disabled
(e) During JOG operation, the acceleration/deceleration time change function
does not function.
POINT
If the speed is changed when an acceleration/deceleration change is enabled, the
"new acceleration/deceleration time" will become the acceleration/deceleration time
of the positioning data being executed. The "new acceleration/deceleration time"
remains valid until the changeover to the next positioning data. (The automatic
deceleration processing at the completion of the positioning will also be controlled
by the "new acceleration/deceleration time".)
(3) Setting the acceleration/deceleration time change function
To use the "acceleration/deceleration time change function", write the data
shown in the following table to the AD75 using the sequence program.
The set details are validated when a speed change is executed after the details
are written to the AD75.
