Identify the exact block number from the alarm detail where execution stopped and review the NC program line.

Check all function parameters against Siemens documentation for that specific system function to verify value ranges and data types.

Verify that R-parameters or variables used as arguments contain valid values by checking their assignment in previous program blocks.

Correct the parameter value or variable assignment to fall within permissible range and retest the program.

Backup the original program before making modifications.

Locate the subroutine or cycle call in the alarm block and list all transfer parameters used.

Cross-reference parameters with the cycle definition or subroutine declaration to verify parameter count, sequence, and value limits.

Check for common errors: negative values where positive required, excessive decimal places, or zero values in divisor positions.

Modify the calling parameters to match the required specification and verify subroutine execution in single block mode.

Use dry run mode for initial testing after parameter correction.

Review the specific technology function call and note the alarm supplementary information for parameter identification.

Access machine data and settings to verify configured limits for the technology function (coordinate system limits, axis ranges, speed limits).

Document current machine data settings before checking.

Compare programmed argument values against both software limits (Siemens specifications) and machine-specific configured limits.

Adjust either the programmed argument to within limits or modify machine data if the requested value is mechanically feasible but restricted by configuration.

Changing machine data requires appropriate authorization and should be documented in maintenance logs.
