Example 12: S-CURVE - Jumping After the Midpoint of Acceleration or
Deceleration
In the following example, a jump occurs during the final phase of deceleration, at the dashed
line. The deceleration continues until constant velocity is reached and then the acceleration
to the higher velocity begins.

S-CURVE Jumps before the Midpoint of Acceleration or Deceleration
If a jump takes place before the midpoint of acceleration or deceleration, the result depends
on whether the velocity at the jump destination is higher or lower than the velocity before
the jump took place. In the first case, when accelerating but the new velocity is lower, or
decelerating and the new velocity is greater, the DSM314 will immediately begin reducing
the acceleration or deceleration to zero. Once at zero velocity, the DSM314 will use the
jump destination acceleration and velocity and change to the new velocity.
Example 13: S-CURVE - Jumping Before the Midpoint of Acceleration or
Deceleration
In the following example, during the acceleration of the first CMOVE, a jump takes place at
the first dashed line. Because the velocity at the jump destination is lower than the velocity
of the first CMOVE the DSM314 slows the acceleration to zero. Constant velocity, zero
acceleration, occurs at the second dashed line. There, the DSM314 begins decelerating to
the new velocity using the acceleration at the jump destination. Finally, the second CMOVE
finishes.
