[2]   "Acceleration/deceleration method setting" control details and 
setting 
In the "acceleration/deceleration method setting", the acceleration/deceleration 
processing method is selected and set. The set acceleration/deceleration 
processing is applied to all acceleration/deceleration.  
The two types of "acceleration/deceleration method setting" are shown below.  
(1)   Automatic trapezoidal acceleration/deceleration processing 
method 
This is a method in which linear acceleration/deceleration is carried out 
based on the acceleration time, deceleration time, and speed limit value set 
by the user.

(2)   S-pattern acceleration/deceleration processing method 
In this method, the motor burden is reduced during starting and stopping.  
This is a method in which acceleration/deceleration is carried out gradually, 
based on the acceleration time, deceleration time, speed limit value, and
