Siemens 840D 101618 - Drive object does not exist
Alarm 101618 indicates that the NCK (Numerical Control Kernel) is attempting to reference a drive axis or spindle object that has not been properly configured or has been deleted from the drive configuration. This typically occurs when there is a mismatch between the NC channel/axis configuration and the actual drive objects defined in the SINAMICS drive system or when drive bus communication has failed.

Root Cause Summary
Alarm 101618 indicates that the NCK (Numerical Control Kernel) is attempting to reference a drive axis or spindle object that has not been properly configured or has been deleted from the drive configuration. This typically occurs when there is a mismatch between the NC channel/axis configuration and the actual drive objects defined in the SINAMICS drive system or when drive bus communication has failed.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access HMI Commissioning mode and navigate to 'Drive System' > 'Topology' to verify all configured axes and spindles have corresponding SINAMICS drive objects.
- 2
Check NC machine data MD30110 (CTRLOUT_TYPE) and MD30111 (CTRLOUT_MODULE_NR) for the affected axis to identify which drive object number is being referenced.
- 3
In STARTER or SINAMICS Integrated, verify the drive object with the matching number exists and is properly configured with the correct telegram type matching MD30130.
Ensure power is off before making hardware verification if replacing drives
- 4
Perform a 'Load drive data to NCK' operation from HMI commissioning menu to synchronize drive topology, then execute a complete power cycle (Power OFF/ON).
Save all current programs and settings before power cycle
