Siemens 840D 100136 - Value too small for display field ->input ignored
SIEMENS alarm 100136 occurs when attempting to enter a numerical value that is below the minimum allowable range for a specific parameter field in the SINUMERIK HMI. The system rejects the input to prevent parameter corruption or unsafe operating conditions.

Siemens 840D 100136 - Value too small for display field ->input ignored
Value too small for display field ->input ignored
Siemens SINUMERIK operator message 100136: Value too small for display field ->input ignored. This is an informational message from the SINUMERIK control indicating a system status or operation result that may require operator action.
Root Cause Summary
SIEMENS alarm 100136 occurs when attempting to enter a numerical value that is below the minimum allowable range for a specific parameter field in the SINUMERIK HMI. The system rejects the input to prevent parameter corruption or unsafe operating conditions.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access servo parameter diagnostics
Navigate to Diagnostics > Service > Drive > Parameters and identify the parameter being modified when alarm occurred.
Check the alarm buffer timestamp to correlate with recent parameter changes
- 2
Verify parameter limits
In Service mode, access the parameter help function (F1) to display the valid range for the specific MD parameter.
Never force parameters outside documented ranges as this can damage servo drives
- 3
Enter valid parameter value
Input a value within the documented minimum/maximum range and confirm with Input key.
Use the parameter calculator in STARTER tool for complex servo tuning parameters
Call a technician if:
- ·Parameter limits require modification beyond operator authority
- ·Servo drive parameters need reconfiguration
- ·HMI display configuration issues persist
Prevention
- Always check parameter help (F1) before entering values
- Use parameter validation tools in SINUMERIK Operate
- Document valid parameter ranges for common adjustments
Common Mistakes
- Entering values in wrong units (mm vs inch)
- Copying parameters between different machine configurations
- Ignoring decimal precision limitations of display fields
