HEIDENHAIN 292-000D - No spindle available for feed per revolution!
Alarm 292-000D occurs when the TNC control attempts to execute feed per revolution (F...R) programming but cannot establish communication with or detect a configured spindle encoder. This typically results from missing spindle configuration, encoder hardware failures, or incorrect parameter settings in the spindle definition tables.

HEIDENHAIN 292-000D - No spindle available for feed per revolution!
No spindle available for feed per revolution!
This TNC7/TNC 640 error indicates a communication-related condition. No spindle is available for the tool. The control has detected an issue that requires investigation.
Root Cause Summary
Alarm 292-000D occurs when the TNC control attempts to execute feed per revolution (F...R) programming but cannot establish communication with or detect a configured spindle encoder. This typically results from missing spindle configuration, encoder hardware failures, or incorrect parameter settings in the spindle definition tables.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access machine parameter tables
Press MOD key, select 'Machine Parameters', navigate to MP7160 series (Spindle Configuration).
Always backup current parameters before making changes
- 2
Verify spindle definition
Check MP7160.x (Spindle Type) is set correctly (0=no spindle, 1=speed controlled, 2=position controlled). Ensure MP7161.x (Spindle Encoder Resolution) contains valid encoder line count.
Incorrect encoder resolution can cause severe machining errors
- 3
Validate spindle assignment
Confirm MP7162.x (Spindle Assignment) matches your machine configuration and MP7163.x (Spindle Input) corresponds to correct encoder input channel.
- 4
Restart control system
Perform controlled shutdown and restart to activate parameter changes. Test with simple G95 feed per revolution move.
Call a technician if:
- ·Encoder hardware replacement required
- ·PLC program modifications needed
- ·Drive amplifier issues suspected
Prevention
- Regular encoder cable inspection
- Periodic spindle positioning accuracy checks
- Maintain proper machine parameter backups
Common Mistakes
- Forgetting to restart control after parameter changes
- Confusing spindle numbers in multi-spindle machines
- Attempting feed per revolution without proper encoder configuration
