Jerk selection
The Jerk selection function selects an appropriate jerk into use based on the elevator
operation mode. The function allows you to:
• define different jerk values for the different elevator operation modes
• enable or disable the use of jerks. When parameter 25.91 JERK DISABLE is
activated, the jerks are internally set to a zero value.
You can obtain the acceleration transition time during a jerk by dividing the selected
acceleration by the jerk value.
The figure below illustrates how the drive uses the jerks.
