Parameter
● Orientation from the forward rotation direction
This method is used to improve the stopping precision and maintain the mechanical precision
when the backlash is large.
If the motor is running in the forward rotation direction, it will make an orientation stop with the
same method as "orientation from the current rotation direction".
If the motor is running in reverse, it will decelerate, the rotation direction will be changed to for-
ward run, and then orientation stop will be executed.
