(3) Stop processing during speed change
If the axis starts decelerating to a stop before the new speed value is reached, the actual deceleration stop time
may not become the same as the set value of "Deceleration stop time."
Ex. When a stop cause occurs in the middle of speed change during speed control

(4) Stop processing during S-curve acceleration/deceleration
If a stop cause occurs while the axis is accelerating according to "S-curve acceleration/deceleration," the S-curve
needed to decelerate from the current speed is recalculated. The axis moves at a constant speed while the
calculation is in progress.
Interruption factor
V
Since pulses are output during constant-speed operation, the positioning address may be reached during
deceleration. In this case, the axis stops immediately upon reaching the positioning address.
(5) Stopping after simultaneous starting of two axes
The axes started by the Two axes simultaneous start instruction (IPSIMUL(P)) are not stopped simultaneously.
Each axis must be stopped separately.( Page 101, Section 7.7.5)
