Departure function DEP CT

Application

The control uses the DEP CT function to depart a contour on a circular path with tangential connection.

Description of function

8H000_44
  • The control departs the contour as follows:
  • On a circular path from the last contour point PE to the end point PN
  • The circular path connects tangentially to the last contour element
  • The circular path from PE to PN is defined by center angle CCA and radius R. The direction of rotation of the circular path depends on the active radius compensation and the algebraic sign of radius R.

The table shows the relationship between the radius compensation, the algebraic sign of the radius R, and the direction of rotation:

  • The following applies regarding the center angle CCA:
  • Only positive input values
  • Maximum input value 360°

Note

If you enter a negative value for the radius R, the position of the end point PN changes.
