Illustration 48: The Acceleration/Deceleration Curve (S-shaped)
11.6.1.2 (ID 103) Acceleration Time 1
Location in the menu: P3.4.1.2
Use this parameter to set the time that is necessary for the output frequency to increase from zero frequency to maximum frequen-
cy.
11.6.1.3 (ID 104) Deceleration Time 1
Location in the menu: P3.4.1.3
Use this parameter to set the time that is necessary for the output frequency to decrease from maximum frequency to zero frequen-
cy.
11.6.2 Ramp 2
11.6.2.1 (ID 501) Ramp 2 Shape
Location in the menu: P3.4.2.1
Use this parameter to make the start and the end of the acceleration and deceleration ramps smoother.
With the parameters Ramp 1 Shape and Ramp 2 Shape, it is possible to make smoother the start and the end of the acceleration and
deceleration ramps. The value set to 0.0% gives a linear ramp shape. The acceleration and deceleration act immediately to the
changes in the reference signal.
The value set between 1.0% and 100.0% gives an S-shaped acceleration or deceleration ramp. Use this function to reduce mechani-
cal erosion of the parts and current spikes when the reference changes. The acceleration time can be modified with parameters
P3.4.2.2 (Acceleration Time 2) and P3.4.2.3 (Deceleration Time 2).
