What causes Siemens SINUMERIK alarm 10962?

Active tool radius compensation (G41/G42) conflicts with the G-code function in the current block. Software version does not support the combination of path correction and the specified function. Incompatible macro or custom function called while tool radius compensation is active. Program logic attempts to use unsupported canned cycles or special functions with active radius offset.

How do I fix Siemens SINUMERIK alarm 10962?

1. Verify the current software version on the 840D/828D control and check Siemens release notes for known limitations with tool radius compensation 2. Review the part program around the flagged block number and identify which function is conflicting with the active G41/G42 compensation 3. Deactivate tool radius compensation (G40) before executing the problematic function, then reactivate compensation (G41/G42) after the function completes if needed 4. Restructure the part program to separate blocks containing path correction-incompatible functions from blocks with active tool radius compensation 5. Contact Siemens support or upgrade to a newer software release that supports the required function combination with path correction active
