Acceleration/Deceleration Time Selection
The normal acceleration/deceleration time is selected during position control. Even if the acceleration/
deceleration time selection is switched or parameter values are changed during position control opera-
tion, the new selection or parameter values are not reflected in operation. These are reflected when
the next position control operation is started.
The following table summarizes acceleration/deceleration time selections.
