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