Pr.34 Acceleration/deceleration process selection

Set whether to use automatic trapezoid acceleration/deceleration or S-pattern
acceleration/deceleration for the acceleration/deceleration process.

Note) Refer to Section 12.7.7 "Acceleration/deceleration process function" for
details.

Speed

Time

The acceleration and
deceleration are linear.

The acceleration and
deceleration follow a Sin curve.

Speed

Time

The S-pattern acceleration/deceleration is disabled when a stepping motor is used.
