When you specify that an action change the value of a constant speed motor or constant force or torque in an eventbased motion study, you can select a profile that defines the feature values during the action.
To display the eventbased view:
From a motion study, in Motion Study Type (MotionManager toolbar), select Motion Analysis, and click Eventbased Motion View (far right of the MotionManager toolbar).
Action Profiles for Changed Feature Values
When defining a change action, you specify the target value for the motor speed, torque, or force at the end of the action. The profile shape, the start value for the motor speed, torque, or force, the end value, and the action duration are used to calculate the feature values during the action.
Linear 

The profile of the feature values is linear: A*t
The amplitude A is calculated from the feature start and end values and the action duration.
t is the value of time during the action.

Constant Acceleration 

The profile second derivative is a step function that is discontinuous at the midpoint of the action duration.
From the action start time up to the midpoint of the action duration, the second derivative is positive with amplitude A.
From the midpoint to the end of the action duration, the value of the second derivative is A.
The amplitude A is calculated from:  Continuity constraints on the first derivative
 Zero value start and end constraints on the first derivative
 The feature start and end values
 The action duration

Cycloidal 

The profile second derivative is the full cycle of a sine function for the action duration: A*sin(2*pi*t)
The amplitude A is calculated from:  Continuity constraints on the first derivative
 Zero value start and end constraints on the first derivative
 The feature start and end values
 The action duration
t is the value of time during the action.

Harmonic 

The profile second derivative is the first half of the cycle of a cosine function for the action duration: A*cos(pi*t)
The amplitude A is calculated from:  Continuity constraints on the first derivative
 Zero value start and end constraints on the first derivative
 The feature start and end values
 The action duration
t is the value of time during the action.

Cubic 

The second derivative is continuous and linear: A*(2*t – 1)
The amplitude A is calculated from:  Continuity constraints on the first derivative
 Zero value start and end constraints on the first derivative
 The feature start and end values
 The action duration
t is the value of time during the action.
