With shorter movement, the deceleration begins before the speed limit is reached, so that the
SP speed limit is not effective. This situation is depicted in the following figure:

11.1.4.2 More Complex PTP Motions
PTP motions may be initiated any time, using the PA command, but not necessarily from
a stationary state. The PTP decisions, made every position control cycle, are described in
the following flowchart. All parameters in the flowchart — including AC, DC, SP and
position target — are updated by a BG command, or by its hardware-activated
equivalent.
