8416 The time required to the maximum acceleration in advanced preview bell--
shaped acceleration/deceleration before interpolation
[Data type] Two--word
[Unitofdata] mec
[Valid data range] 0 to 99999999
This parameter sets the time required to reach the maximum acceleration
in advanced preview bell--shaped acceleration/deceleration before inter-
polation.
Also, this parameter is used for deceleration time taken from the
maximum acceleration to zero.

When target speed is different, total time also
changes (constant acceleration).
