(6) [Pr.34] Acceleration/deceleration process selection
Set whether to use trapezoid acceleration/deceleration or S-curve acceleration/deceleration for the
acceleration/deceleration process.
(Refer to

Page 596, Section 12.7.6 for details.)
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.
