Check active coordinate system

Press MANUAL DATA INPUT, then MOD function, check which coordinate system (G54-G59) is active and verify the preset values in the PRESET TABLE.

Use the ACTUAL POSITION display to see both workpiece and machine coordinates simultaneously

Verify preset table entries

Access PRESET TABLE via MOD function, check if the active preset (REF column) has reasonable offset values that don't push the working envelope beyond machine limits.

Never modify presets without proper workpiece setup verification

Recalculate workpiece position

Use PRESET function to establish a new workpiece datum closer to machine center, ensuring adequate clearance from positive limits defined in MP91x.x parameters.

Review program at alarm position

In PROGRAM RUN mode, note the block number where alarm occurred, then switch to PROGRAMMING mode and examine the coordinate values in that block and preceding blocks.

Use the GRAPHICS simulation to visualize the complete tool path before running

Check coordinate mode

Verify if program uses G90 (absolute) or G91 (incremental) positioning, and ensure coordinate values are appropriate for the current workpiece setup.

Validate with machine parameters

Access machine parameters via MOD function, check MP91x.x values for the affected axis, and compare against programmed coordinates plus WCS offsets.

Check active tool data

Access TOOL TABLE via MOD function, verify the LENGTH (L) value for the currently active tool number matches the actual tool geometry.

Use TOOL CALL T0 to cancel tool compensation and test if alarm persists

Verify tool measurement

If equipped with tool probe, re-measure the tool using TOOL MEASUREMENT cycle, or manually verify tool length against tool preset station measurements.

Check Z-axis reference point

Ensure the machine reference point and workpiece preset provide adequate Z-axis travel for the tool length compensation being applied.

Access machine parameters

Enter MOD function, access MACHINE PARAMETERS, locate MP91x.x series for traverse limits, and compare values against machine specifications.

Machine parameter changes require proper authorization and can affect machine safety

Verify reference point position

Perform reference point approach for all axes and confirm the machine coordinate display matches expected reference positions relative to mechanical limits.

Consult machine documentation

Review machine builder specifications for correct traverse range values and compare against current MP91x.x settings before making any parameter modifications.

Always backup machine parameters before making changes using the data backup function
