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.

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,
