In this operation mode, the servo motor automatically changes the direction for the shortest distance and
executes positioning.
(1) When not using the remote register
Select the station number using 8-bit device of the next station selection 1 to 8 (RYnA to RYnE, and
RY(n 2)3 to RY(n 2)5), and execute positioning. For the servo motor speed and acceleration/
deceleration time constant during operation, the value set in the point table is used.
