What causes Siemens SINUMERIK alarm 100122?

Required machine data or parameter not configured for the requested function. Option bit not set in SINUMERIK to enable the required functionality. Program references a function or axis that has not been configured. Machine commissioning incomplete — required setup step was not performed. Configuration data cleared or lost due to a parameter reset or hardware change.

How do I fix Siemens SINUMERIK alarm 100122?

1. Read the full alarm message to identify what is missing (axis name, parameter number, function name). 2. Consult the SINUMERIK alarm manual for alarm 100122 for the specific configuration requirement. 3. Check the relevant machine data group and set the required parameter. 4. If a specific option is required, verify it is licensed and enabled in the SINUMERIK option settings. 5. Power cycle after making configuration changes to apply the new settings.

Ensure qualified technician performs repairs

Causes and Fixes

1
Check Current Access Level
Navigate to HMI → Diagnostics → Service → Access Rights to verify current user access level and compare against required level for servo parameters.
2
Login with Higher Privileges
Access HMI → Startup → Access Rights → Password and enter manufacturer password (typically level 2-4 required for servo parameters).
Level 2 (Service) is usually sufficient for most servo parameter modifications
3
Verify Parameter Access
Navigate to Parameters → Machine Data → Servo and attempt to modify the previously restricted parameter to confirm access rights.
