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.)

*1. For the relation between the time for the actual deceleration and the specified time for desired
deceleration, refer to the following.
4. Linear interpolation operation
If the time necessary for the travel distance (target address 1) is smaller than the acceleration/deceleration
time, the actual operation speed does not reach the command speed.
5. Linear interpolation operation (interrupt stop)
If the time necessary for the travel distance (target address 1) is smaller than the deceleration time, the output
pulses stop at the deceleration target address 1 (target address 1).
If the travel distance is zero, the operation immediately stops at the interrupt input (INT0) ON.
6. Interpolation operation (during continuous pass operation)
If the travel distance is small and the travel time from the starting point to the end point is shorter than the
interpolation time constant, the operation temporarily stops, and then shifts to the next interpolation operation.
