Check the alarm detail screen to identify the specific error number (%1) and location (%2). Note the exact NC block number referenced.

Open the NC program in the editor and navigate to the block number indicated by %2. Examine the syntax for missing parameters, incorrect decimal points, or invalid command combinations.

Cross-reference the error number %1 with the SINUMERIK error code documentation to identify the specific programming violation (e.g., invalid axis name, missing feedrate, undefined tool number).

Correct the identified syntax error, verify the program structure, and reset the alarm using the NC START or RESET key before restarting the program.

Identify the specific parameter causing the error from the %1 and %2 variables displayed with the alarm. Check if it references feedrate (F), spindle speed (S), coordinates, or tool number (T/D).

Access the machine data settings via 'Commissioning' mode and verify the parameter limits (MD36xxx for axis limits, MD35xxx for feedrates). Compare programmed values against these limits.

Changing machine data requires access rights and can affect machine safety. Document original values before any modifications.

If tool-related, verify the tool number exists in the tool list (TCM) and tool offset data is properly defined. Check for tool length compensation (G43) with undefined tool offsets.

Modify the NC program to use values within the allowable range, or if machine data limits are incorrect, adjust them according to actual machine specifications and manufacturer guidelines.

Check if the program calls standard cycles (CYCLE8x) or manufacturer-specific cycles that may not be installed or properly configured in the system. Review the error text for cycle-related references.

Verify all subroutine calls (L-commands) reference existing programs in the correct directory (_N_SPF_DIR or _N_MPF_DIR). Check for case-sensitive naming issues or missing file extensions.

Review coordinate system definitions (G54-G59, frames) and ensure the called work offset is properly set up in the offset memory. Check for undefined or corrupted frame data.

If the error persists, perform a PLC diagnostics check and verify all necessary option bits are enabled for the functions being used (transformation packages, high-speed machining, etc.). Consult system configuration documentation.

Enabling software options may require proper licensing. Contact Siemens service if option activation is needed.
