• 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".
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 method
To use the "acceleration/deceleration time change function", write the data shown in the following table to the
LD75 using the program.
The set details are validated when a speed change is executed after the details are written to the LD75.
Refer to

Page 211, Section 5.7 for the information on detail settings.
