Control precautions
• When 0 is set in [Cd.10] New acceleration time value and [Cd.11] New deceleration time value, the acceleration/
deceleration time is not changed even if the speed change is performed. In this case, the operation is controlled at the
acceleration/deceleration time previously set in the parameters.
• New acceleration/deceleration time is valid during the execution of the positioning data for which the speed change was
performed. In the continuous positioning control and continuous path control, even though the speed change is performed
and the acceleration/deceleration time has been changed to the new acceleration/deceleration time ([Cd.10] and [Cd.11]),
the control will be performed at the previously set acceleration/deceleration time when switching to the next positioning
data is performed.
• Even if the acceleration/deceleration time change is set to be disabled after New acceleration/deceleration time is
validated, the positioning data for which New acceleration/deceleration time was validated continues to be controlled with
that value. (The next positioning data is controlled at the acceleration/deceleration time set in the parameters in advance.)

• If New acceleration/deceleration time is set to 0 and the speed change is performed after New acceleration/deceleration
time is validated, the operation is controlled at the previous New acceleration/deceleration time.
