What causes Siemens SINUMERIK alarm 100411?

Part program contains an illegal or unsupported command for the current machine configuration. Parameter or machine data setting incompatible with the commanded operation. Required option or function not enabled on this SINUMERIK control. Incorrect axis assignment or configuration for the commanded function. Software version or compile cycle version mismatch.

How do I fix Siemens SINUMERIK alarm 100411?

1. Note the full alarm message including any parameter values shown (e.g., axis number, block number, channel). 2. Identify the program block or operation that triggered the alarm. 3. Review the SINUMERIK alarm manual for alarm 100411 to identify the specific cause and remedy. 4. Check the relevant machine data parameters referenced in the alarm. 5. If the alarm persists after correcting the program, contact Siemens technical support with the full alarm text and machine data backup.

Alarm 100411

Siemens 840D 100411 - Error var. access: Value < minimum value

SINUMERIK alarm 100411 occurs when a servo parameter or variable is set below its defined minimum threshold value. This typically happens during parameter modification in servo commissioning menus or through PLC variable assignments that violate the parameter's valid range.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Access servo parameter display
Navigate to HMI > Diagnostics > Service > Drive > Parameters and identify the axis showing the alarm.
Use the alarm buffer timestamp to correlate with recent parameter changes
2
Check parameter limits
In HMI > Commissioning > Servo > Axis selection, review parameters like MD32000 (DRIVE_AX_NAME) related settings and verify against minimum values in parameter descriptions.
Document original values before making changes
3
Correct parameter value
Adjust the parameter to within valid range using the parameter's help text minimum value, then perform Control Reset via HMI > Machine > Control Reset.

DIY Feasiblehigh confidence

Call a technician if:

·Parameter changes cause mechanical damage
·Drive hardware replacement needed
·Encoder calibration required

Prevention

Always backup parameters before modifications
Use parameter validation in commissioning software
Document minimum/maximum limits for custom applications

Common Mistakes

Setting zero values for critical parameters
Ignoring parameter help text limits
Not performing control reset after parameter changes
