Unexpected behavior when processing jerk specifications

The time-based operating modes speed control (Velocity), absolute positioning (Positioning), relative positioning (PositioningRelative), jog (Jog), and homing (Homing) described in the following chapters allow the jerk to be controlled directly via the variable lrJerk. This chapter describes scenarios in which unexpected behavior of the axis in question can occur, especially when switching from a large jerk to a small jerk in certain phases of the movement.

NOTICE

Unexpected system behavior due to reversing of the drive, especially when switching from a large jerk to a small jerk in certain phases of the movement. The user is responsible for ensuring that the control configured for profile generation does not result in unexpected behavior.
Death, severe injuries, damage to property
  • Check the effects of an unexpected reversing of the drive in your application. To prevent unexpected reversing of the drive, treat the preset jerk as a uniquely configured quantity or change it only if the currently effective acceleration is close to the value "0".
