What causes Siemens SINUMERIK alarm 100110?

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 100110?

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 100110 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 100110

Siemens 840D 100110 - Read access not allowed in this state

SIEMENS alarm 100110 occurs when the system attempts to read servo drive parameters or data while the drive is in an incompatible operational state. This typically happens during active motion, drive initialization sequences, or when the servo is in a fault condition that prevents parameter access.

Root Cause Summary

SIEMENS alarm 100110 occurs when the system attempts to read servo drive parameters or data while the drive is in an incompatible operational state. This typically happens during active motion, drive initialization sequences, or when the servo is in a fault condition that prevents parameter access.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Check drive operating state
Navigate to Diagnostics > Drive > Status and verify the current drive state. Look for RUN, ACTIVE, or motion-in-progress indicators.
Use DB31 DBX60.0 (servo enable) and DB31 DBX60.1 (drive ready) to verify exact drive status
2
Stop active motion
Execute M00 program stop or press NC STOP to halt all axis movement. Wait for drives to reach STANDBY state.
Ensure workpiece and tooling are in safe position before stopping motion
3
Retry parameter access
Access Commissioning > Drive > Parameters or use SINAMICS Startdrive to read the required parameters once drives are in STANDBY state.
4
Verify parameter access rights
Check machine data MD30240 (DRIVE_PARAMETER_ACCESS_LEVEL) to ensure sufficient access level for the parameter being read.

DIY Feasiblehigh confidence

Call a technician if:

·Drive hardware faults persist after clearing
·Safety system configuration issues
·Firmware compatibility problems

Prevention

Always stop motion before accessing drive parameters
Maintain proper user access level management
Monitor drive status before parameter operations
Keep SINAMICS firmware updated

Common Mistakes

Attempting parameter access during active machining
Ignoring drive fault conditions
Using insufficient access level
Not waiting for commissioning completion
