HEIDENHAIN 230-04E5 - Incorrect UVR/UEC configuration, index invalid
Alarm 230-04E5 occurs when the HSCI (High Speed Communication Interface) UV index parameter in CfgSupplyModule3xx is configured with an invalid value. This typically happens during UVR/UEC module configuration when the hsciUvIndex parameter references a non-existent or incorrectly numbered UV channel.

HEIDENHAIN 230-04E5 - Incorrect UVR/UEC configuration, index invalid
Incorrect UVR/UEC configuration, index invalid
This TNC7/TNC 640 error indicates an issue with 230-04E5. No valid value entered for the machine parameter CfgSup- plyModule3xx > hsciUvIndex.
Root Cause Summary
Alarm 230-04E5 occurs when the HSCI (High Speed Communication Interface) UV index parameter in CfgSupplyModule3xx is configured with an invalid value. This typically happens during UVR/UEC module configuration when the hsciUvIndex parameter references a non-existent or incorrectly numbered UV channel.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Access machine parameters
Press MOD key, select 'Machine Parameters', navigate to CfgSupplyModule3xx section using search function.
Use Ctrl+F to quickly search for 'hsciUvIndex' parameter
- 2
Verify hsciUvIndex value
Check the current value of hsciUvIndex parameter and compare against available UV channels (typically 0-7 for standard configurations).
Document original values before making changes
- 3
Cross-reference UV channel configuration
Navigate to CfgAxisUV section to verify which UV channels are actually configured and active in the system.
- 4
Correct the index value
Set hsciUvIndex to a valid UV channel number that exists in your system configuration, typically starting from 0.
Most systems use sequential numbering starting from 0 for UV channels
Call a technician if:
- ·Parameter corruption persists after reset
- ·UV axis configuration conflicts with machine mechanics
- ·Software update required
Prevention
- Regular parameter backups
- Validate UV channel configuration during setup
- Document all UV axis assignments
- Use parameter templates for consistent configuration
Common Mistakes
- Using 1-based indexing instead of 0-based
- Configuring hsciUvIndex without corresponding UV axis
- Copying parameters between different TNC versions
- Not validating parameter ranges after software updates
