Axis not within position window at end of settling time.

Description

The axis is not within the tolerance window at the end of the settling time.

 

The position lag monitoring function (see [FCT-A3// Section: Description]) monitors whether the actual position reaches an exact stop window (see P-AXIS-00236) within a certain period of time (see P-AXIS-00532) when approaching a target position. If the interpolator no longer supplies any command values, the command position of the axis has reached its programmed target position and time monitoring is started. It is deactivated when the actual position of the axis is within the exact stop window.

 

Possible error causes:

  • An incorrectly adjusted position controller, e.g. excessive permanent control deviation or excessive overshoot.
  • Excessive friction in the mechanical system.
  • The axis is blocked and cannot move freely

Response

Class

5

Abrupt axis stop for defective axis

Solution

Class

6

Possible solutions:

  • Increase the proportional gain factor of the position controller if the control deviation is excessive.
  • Reduce the gain factor of the position controller if the axis oscillation is excessive (see P-AXIS-00099).
  • Reduce friction in the mechanical system
  • If necessary, increase the exact stop window (see P-AXIS-00236) or the settling time (see P-AXIS-00532)
