Siemens alarm 14920: Channel %1 block %2 intermediate point of circle incorrect

What it means

For a circle through three points (CIP), the programmed intermediate point does not define a unique circle together with start and end - typically because all three points are collinear or coincident. Choose an intermediate point off the connecting line of start and end.

Likely causes

• Intermediate point collinear with start and end
• Intermediate point identical to start or end point
• Coordinate typo placing I1/J1/K1 wrongly
