HEIDENHAIN 230-04C3 - Brake outputs are ignored
Alarm 230-04C3 occurs when brake control outputs are defined in the IOCP configuration file but the current machine hardware configuration does not support these brake control functions. The TNC control detects this mismatch between software configuration and hardware capabilities during system initialization.
230-04C3
HEIDENHAIN 230-04C3 - Brake outputs are ignored
Brake outputs are ignored
Brake control outputs defined in IOCP are not supported by this machine configuration and will be ignored.
Root Cause Summary
Alarm 230-04C3 occurs when brake control outputs are defined in the IOCP configuration file but the current machine hardware configuration does not support these brake control functions. The TNC control detects this mismatch between software configuration and hardware capabilities during system initialization.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check servo drive specifications
Verify in MOD 9906 (Machine Parameters) if the connected servo amplifiers support brake control outputs. Check drive model numbers against Heidenhain compatibility documentation.
- 2
Review IOCP brake definitions
Open the IOCP file and locate brake output assignments. Look for entries like 'BRAKE_OUT_X', 'BRAKE_OUT_Y', etc. and note which axes have brake outputs defined.
- 3
Match hardware to configuration
Compare the IOCP brake definitions with actual servo drive capabilities. Remove brake output definitions for drives that don't support brake control.
Use Heidenhain's ConfigDesign software to validate IOCP configurations before deployment.
Call a technician if:
- ·Hardware modifications required
- ·Software licensing issues
- ·IOCP regeneration beyond operator capability
Prevention
- Always validate IOCP files with actual hardware before deployment
- Maintain accurate documentation of installed brake control hardware
- Use ConfigDesign software for IOCP file creation and validation
Common Mistakes
- Assuming all servo drives support brake control
- Not removing brake definitions when hardware is removed
- Using IOCP files from different machine configurations
