ID 70331

Tactile deviation too big.

Description

The correction value offset calculated by the distance control (see FCT-M3) exceeds the permissible limit. Due to safety reasons, the maximum deviation caused by the distance control between the programmed position in the NC program and the real actual position of the axis can be limited with the parameter P-AXIS-00414.

 

Possible error causes:

  1. The deviation between command height (SET_POS) and actual height of the workpiece surface is too large. In this case, the command height should be compensated and the NC program should be regenerated with the new command height.
  2. The workpiece may possibly contain a large indentation at this point, e.g. a hole. Deactivate distance control at the position to avoid a collision with the workpiece. In addition, there is a risk of possible damage to the probe if a (contacting) sensor is used.
  3. Strong changes in height of workpiece surface. In this case, an attempt can be made to increase the permissible limit P-AXIS-00414. Possibly reduce path velocity so that distance control can follow the strong changes in height.
