Identify the Parameter Field

Note which machine data parameter was being modified when alarm occurred. Check HMI display for the active MD number and field name.

The alarm typically appears immediately after pressing ENTER or INPUT key

Verify Parameter Limits

Access SINUMERIK documentation or use HMI Help function to check valid range for the specific MD parameter. Navigate to Diagnostics > Help > Machine Data.

Never guess parameter ranges - always verify against official documentation

Enter Corrected Value

Input a value within the documented range limits. Use proper decimal notation and ensure no leading/trailing spaces or invalid characters.

Use scientific notation (e.g., 1.5E-3) for very small values if supported by the parameter

Validate and Reset

Press INPUT key to confirm entry. If accepted, press RESET key to clear alarm. Cycle power if parameter requires restart to take effect.

Access Tool Management

Navigate to Parameters > Tool Data or press TOOL key. Identify which tool number and offset type (length/radius/wear) caused the alarm.

Check both geometry and wear offset fields as both have range limitations

Verify Tool Offset Limits

Check MD18102 (max tool length) and MD18104 (max tool radius) for system-defined limits. Standard range is typically ±99999.999mm.

Extremely large offset values may indicate measurement or calculation errors

Correct Tool Data Entry

Re-enter tool offset value within permissible range. Ensure proper sign convention (+ or -) and decimal placement.

Use tool presetter or manual measurement to verify actual tool dimensions

Confirm and Test

Press INPUT to accept value, then RESET to clear alarm. Perform dry run or single block execution to verify tool compensation is working correctly.

Identify Setting Data Parameter

Note the SD parameter number and description where the alarm occurred. Access via Parameters > Setting Data menu.

Setting data parameters often have more restrictive ranges than machine data

Check Data Type Requirements

Verify if parameter requires INTEGER, REAL, or BOOLEAN data type. Check SINUMERIK Lists Manual for SD parameter specifications.

Mixing data types (entering decimal for integer parameter) will trigger this alarm

Enter Proper Format Value

Input value matching exact data type and range requirements. Use whole numbers for INTEGER types, proper decimal notation for REAL types.

For BOOLEAN parameters, use 0 (FALSE) or 1 (TRUE) only

Validate Entry

Press INPUT key and verify acceptance. Clear alarm with RESET. Check if setting data change requires NCK restart via HMI restart menu.

Access Work Offset Menu

Navigate to Parameters > Work Offsets or press OFFSET key. Identify which coordinate system (G54, G55, etc.) and axis caused the alarm.

Check all axes (X, Y, Z) as the alarm may not specify which axis exceeded limits

Check Software Limit Switches

Review MD36010 (negative software limit) and MD36020 (positive software limit) for each axis to determine maximum allowable coordinate range.

Work offset values that place workpiece outside software limits will cause this alarm

Recalculate Work Offset

Measure workpiece setup and calculate work offset values that keep all programmed coordinates within software limits. Consider relocating workpiece if necessary.

Use workpiece probing cycle to automatically calculate accurate work offsets

Apply and Verify Offsets

Enter corrected work offset values and press INPUT. Clear alarm with RESET. Test with G-code simulation or dry run to verify coordinate validity.

Analyze Input String Length

Count total characters in entered value including decimal point, signs, and spaces. Most SINUMERIK numeric fields limit to 10-15 characters maximum.

Remove unnecessary leading zeros and trailing decimal places

Check for Invalid Characters

Ensure only valid numeric characters (0-9), decimal point, and +/- signs are used. Remove any letters, spaces, or special characters.

Some international keyboard layouts may insert invalid characters

Optimize Number Format

Use scientific notation for very large or small numbers. Reduce decimal places to minimum required precision (typically 3-4 decimal places maximum).

SINUMERIK accepts E-notation: 1.234E+5 for large numbers, 1.234E-5 for small numbers

Re-enter Formatted Value

Input the properly formatted numeric value within character limits. Press INPUT to confirm and RESET to clear alarm.
