Identify the NC block number from the alarm detail display on the HMI and locate it in the part program.

Check for duplicate addresses in the block (e.g., two X values, two F values) and remove the duplicate or split into separate blocks.

Verify that all addresses used are valid for the active G-code group (e.g., I, J, K only valid with G02/G03 circular interpolation).

Correct the NC program, reset the alarm, and test the program in single block mode.

Always backup the original program before making modifications.

Review the alarm block and identify any unusual or non-standard address letters (e.g., U, V, W on machines without these axes configured).

Check machine data MD10000 (AXCONF_MACHAX_NAME_TAB) to verify which axis addresses are configured and available.

Access to machine data requires appropriate password level - document original values before any changes.

If the address should be valid, verify channel-specific axis configuration in MD20070 (AXCONF_CHANAX_NAME_TAB) for the active channel.

Either modify the NC program to use correct available addresses or contact the machine tool builder if additional axes need configuration.

Examine the program block and the surrounding blocks to understand the active mode (milling, turning, grinding) and technology package.

Verify that addresses like AC (angle for contour definition) or radius programming (CR=) are used only where applicable for the current technology.

Check if the block is part of a cycle call (CYCLE, MCALL) and ensure only addresses documented for that specific cycle are used.

Correct the NC program by removing impermissible addresses or restructuring to use appropriate commands for the active mode.
