Siemens alarm 61907: Pocket contour missing

What it means

A pocket milling cycle that reads its geometry from a contour description found no pocket contour at the referenced location. Without the closed pocket outline the cycle cannot generate paths. Load the contour subroutine and verify the contour call.

Likely causes

• Pocket contour subroutine not transferred to the control
• Label/name mismatch between call and contour program
• Contour stored in a directory the cycle does not search
