Pr.34 Acceleration/deceleration process selection

Set whether to use automatic trapezoid acceleration/deceleration or S-pa ttern

acceleration/deceleration for the acceleration/deceleration proces s.

Note) Refer to Section 12.7.7 "Acceleration/deceleration process func tion" for

details.

Speed
Time
The acceleration and
deceleration are linear.

<Automatic trapezoid acceleration/deceleration> <S-pattern acceleration/deceleration>

The acceleration and
deceleration follow a Sin curve.

Time

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