S-CURVE Jumps to a Higher Acceleration while Accelerating or a lower
Deceleration while Decelerating
The second case involves jumping to a higher velocity while accelerating or a lower velocity
while decelerating. When this
occurs, the DSM314 continues to the first move’s
acceleration or deceleration. This acceleration or deceleration is maintained, similar to be a
linear acceleration, until the axis approaches the new velocity. Then the normal S-curve is
used to reduce acceleration or deceleration to zero.
Example 14: S-CURVE - Jumping to a Higher Velocity While Accelerating or
Jumping to a Lower Velocity While Decelerating
In this example, a JUMP command is triggered during the initial phase of acceleration (at the
first dashed line) and the velocity at the jump destination is higher than that of the current
move. The first dashed line indicates the maximum acceleration of the first CMOVE. This
value is held as the axis continues to accelerate until it s-curves back to constant velocity.
Constant velocity, the second dashed line, indicates the beginning of the second CMOVE.
This move continues until it decelerates to zero at the end of the program.
