9 S-Curve
There are eight standard options for adjusting the S-Curve.
• Acceleration – Maximum acceleration for the profile.
• Accel Jerk In – How quickly the profile transitions from minimum acceleration speed to
full acceleration. Higher values result in a sharper start.
• Accel Jerk Out – How quickly the profile transitions from maximum acceleration to zero
acceleration.
• Deceleration – Maximum acceleration for the profile.
• Decel Jerk In – How quickly the profile transitions from zero deceleration to maximum
decelerations.
• Decel Jerk Out – How quickly the profile transitions from maximum deceleration to
leveling speed.
• Leveling Speed – The speed at which the elevator levels into the floor.
• Leveling Distance – The stabilized distance the elevator travels before arriving at the
destination floor.
NOTE: Decel Jerk In and Decel Jerk Out are not shown during Inspection mode.
The following is a graphical image of the parameters that are being adjusted.
