2) If the travel distance of the second speed is small
If the travel time at the second speed is smaller than the time
speed 2, deceleration is started from operation speed 1.
If the travel distance at the second speed is zero, the operation decelerates to stop for the travel distance
to be the target address 1 as if it were a 1-speed positioning operation. (No error is caused.)
