4. 2-speed positioning operation
1) If the travel distance at the first speed is small
If the travel time is smaller than the time
operation speed does not reach the operation speed 1.
If the travel distance of the first speed is zero, the travel is at the second operation speed and travel
distance. (No error is caused.)
