Function Sets the acceleration/deceleration pattern.
For the acceleration/deceleration pattern, select either linear acceleration/deceleration or
jerk-limit control. The acceleration/deceleration pattern set here is common to positioning,
continuous and mechanical home seeking operations (excluding the two-axis linear
interpolation operation).
Jerk-limit time will be valid when the acceleration/deceleration pattern is set to jerk-limit
control. This setting will be invalid under the linear acceleration/deceleration setting.

About jerk-limit time
Set the jerk-limit time when the acceleration/deceleration pattern is set to jerk-limit control mode.
Jerk-limit time n2 applies to the sections shown in the diagram below.
A: Jerk-limit acceleration/deceleration area
