Causes and Fixes

1
Access Siemens SINUMERIK HMI > Diagnosis > Machine Data. Navigate to MD20050 and verify the value is a positive integer between 1 and the maximum supported spindles (typically 8-16 depending on 840D/840D sl version).
Do not modify MD20050 while spindles are active; request machine stop and control system readiness status.
2
If MD20050 is blank or shows 0, enter the correct spindle count. If the value appears corrupted, restore machine data from a known-good backup using NCK backup/restore function in HMI > Service > Backup.
3
After correction, perform a cold start: Power cycle the machine control or execute NCK reset via HMI > Service > Reset NCK. Monitor system startup messages in the alarm log.
