Siemens 840D 10757 - Channel block changing the compensation plane while tool
Channel block changing the compensation plane while tool
In order to change the compensation plane (G17, G18 or G19) it is first necessary to deselect the cutter radius compensation with G40.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Active cutter radius compensation (G41/G42) when attempting to change compensation plane (G17/G18/G19)
- Programming error where G17/G18/G19 command issued before G40 deselection
- Macro or subroutine executing plane change without first canceling tool radius offset
- Operator manually selecting different plane while compensation is still active
- Post-processor generating incorrect NC code sequence
Troubleshooting Steps
- 1Review the NC program at the flagged block %2 in channel %1 to identify the exact sequence of G-codes
- 2Verify that G40 (cancel cutter radius compensation) is programmed before any G17/G18/G19 plane selection command
- 3Check for active compensation state from previous blocks that may not have been properly cleared
- 4Examine any macros, subroutines, or cycle calls that may be issuing plane change commands without proper G40 deselection
- 5Correct the program sequence to insert G40 before the plane change command and re-run the block
