HEIDENHAIN 230-01BE - AxisMode and AxisHw for axis do not match
HEIDENHAIN alarm 230-01BE occurs when there is a mismatch between the configured axis mode (axisMode) and axis hardware type (axisHw) parameters in the machine configuration. This typically happens during initial setup, after hardware changes, or when configuration files are incorrectly modified.
230-01BE
HEIDENHAIN 230-01BE - AxisMode and AxisHw for axis do not match
AxisMode and AxisHw for axis do not match
The axisMode and axisHw settings for this axis form an illegal pair. Only certain hardware types are valid for each mode level.
Root Cause Summary
HEIDENHAIN alarm 230-01BE occurs when there is a mismatch between the configured axis mode (axisMode) and axis hardware type (axisHw) parameters in the machine configuration. This typically happens during initial setup, after hardware changes, or when configuration files are incorrectly modified.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access machine configuration
Press MOD key, select 'Machine Parameters' and navigate to MP7500 series (axis configuration parameters).
Always backup current configuration before making changes
- 2
Check axis mode setting
Verify MP7501.x (axisMode) for the affected axis is set to 'Active' and note the current axisHw setting in MP7502.x.
Document original settings before modification
- 3
Correct axisHw parameter
Set MP7502.x (axisHw) to appropriate value: InOutCC for standard servo axes, AnalogMC/CC for analog drives, or DisplayMC/CC for display-only axes.
- 4
Restart control
Perform a complete control restart (CTRL+ALT+DEL) to activate the new configuration parameters.
Call a technician if:
- ·Hardware damage suspected
- ·Multiple configuration backups corrupted
- ·Uncertainty about drive hardware types
Prevention
- Always backup configuration before hardware changes
- Document axisMode/axisHw combinations during commissioning
- Use TNCopt for offline parameter validation
- Maintain configuration change log
Common Mistakes
- Setting Virtual axis axisHw to anything other than None
- Forgetting to restart control after parameter changes
- Mixing up AnalogMC vs AnalogCC settings
- Not updating configuration after drive replacements
