*1. Set approximate S-shaped acceleration/deceleration or trapezoidal acceleration/deceleration in
"acceleration/deceleration mode."
2. Interrupt 1-speed positioning operation
(Ver. earlier than 1.10, or BFM#519, #619 b6=OFF in Ver. 1.10 or later)
If the time needed for the travel distance (target address 1) is shorter than the deceleration time, the pulse
output stops at the target address 1.
If the travel distance is zero, immediate stop occurs when interrupt input INT0 turns ON.

time
Approximate S-shaped control
The time to stop is slightly earlier because
deceleration under the approximate S-shaped
control is slower than that of trapezoidal control,
while the travel distance is almost the same as
that of trapezoidal control.
