61280

Navigate to Diagnosis > Machine Data (MD) > 20080 (Mirror axes in work offset). Verify mirroring is enabled for the active work offset number referenced in alarm block %4.

Check the work offset table (Offset > Geometry) in the control to confirm the offset WO %4 has mirroring axes defined (typically X-axis for counterspindle applications). Verify bits are set correctly in MD 20080.

Mirroring must match machine kinematic configuration for counterspindle.

If mirroring is not configured, enable it via Machine Data > 20080 and specify axes to mirror. Save and restart the NCK to apply changes.

Re-run the program block %2 to verify the F_SUB_SP cycle executes without alarm 61280.

Review the NC program sequence before block %2. Verify a G54-G59 command (or G10 P offset number) is executed before any SPON, SPOF, or F_SUB_SP calls.

Counterspindle movement must be preceded by work offset selection with mirroring active.

Confirm the selected offset (WO %4 from alarm) has mirroring enabled in the offset table. Check Offset > Geometry menu and verify the mirroring column shows 'X' or appropriate axis.

Insert the correct offset call (e.g., G54 or G10 P1) before the F_SUB_SP cycle or counterspindle activation command in the program.

Verify program block sequence and re-execute to confirm alarm 61280 is resolved.

Check the F_SUB_SP cycle implementation in Utilities > Program > Cycles. Identify which work offset number is being used and cross-reference with alarm parameter %4.

Navigate to Machine Data > 20080 (Mirror axes in work offset) and confirm the offset WO %4 has mirroring enabled. Verify MD 20090 (Mirroring type) is set to match machine configuration (typically '0' for standard mirroring).

Mirroring type must match machine kinematic setup.

Inspect the offset record (Offset > Geometry) for WO %4. Ensure all required mirroring fields are populated. If offset does not exist, create it with mirroring enabled via Offset > New Offset.

Execute a test program with explicit offset selection (G54/G59) followed by F_SUB_SP to validate mirroring is active before counterspindle movement begins.
