Profile Operand
This operand has two profile types:
• Trapezoidal Velocity Profile
• S-curve Velocity Profile
Trapezoidal Velocity Profile
The trapezoidal velocity profile is the most commonly used profile because it
provides the most flexibility in programming subsequent motion and the
fastest acceleration and deceleration times. Acceleration and deceleration
specify the change in velocity per unit time. Jerk is not a factor for trapezoidal
profiles. Therefore, it is considered infinite and is shown as a vertical line in the
following graph.
