Pr.34 Acceleration/deceleration process selection
Set whether to use trapezoid acceleration/deceleration or S-curve
acceleration/deceleration for the acceleration/deceleration process.
Note) Refer to Section 12.7.6 "Acceleration/deceleration process function" for
details.
Speed
The acceleration and
deceleration are linear.
Time
<Trapezoid acceleration/deceleration>
<S-curve acceleration/deceleration>
Time
Speed
The acceleration and
deceleration follow a sine curve.
For the system that uses a stepping motor, executing the S-curve
acceleration/deceleration may cause step-out.
Before using the S-curve acceleration/deceleration, confirm that step-out does not
occur.
