Causes and Fixes

1
Access Siemens SINUMERIK HMI > Diagnostics > Alarms and note the exact axis/drive reporting 8037.
2
In NCK Parameters (MD), navigate to MD10200 'Enable options' and verify the APC option bit is set. Cross-reference with your system license documentation.
Modifying MD10200 requires write access and system reload.
3
If MD10200 is correct, check drive parameter P-0-0080 (or axis-specific APC enable) and disable APC in the drive until license is procured.
4
Execute a full system RESET (warm start) after parameter correction to clear cached licensing state.
