Heidenhain 320-0003 - Argument out of range
HEIDENHAIN alarm 320-0003 'Argument out of range' occurs when a parameter value exceeds the allowable limits defined in the TNC control system. This typically happens during axis positioning, feed rate commands, or when invalid numerical values are passed to system functions or PLC operations.

Heidenhain 320-0003 - Argument out of range
Argument out of range
Heidenhain error 320-0003: Argument out of range. A PLC or machine logic error has been detected. The machine's programmable logic controller has reported a fault that prevents normal machine operation.
Root Cause Summary
HEIDENHAIN alarm 320-0003 'Argument out of range' occurs when a parameter value exceeds the allowable limits defined in the TNC control system. This typically happens during axis positioning, feed rate commands, or when invalid numerical values are passed to system functions or PLC operations.
Safety
- Refer to Heidenhain service manual
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check current axis positions
Press POS key and verify all axis positions are within expected ranges. Look for extremely large position values that may indicate encoder issues.
Use REF ALL function if positions appear corrupted
- 2
Verify software travel limits
Access MOD function, select machine parameters, check MP1010-MP1017 for X/Y/Z axis limits. Ensure commanded position is within these boundaries.
Modifying travel limits requires machine manufacturer authorization
- 3
Reset position if corrupted
If position values are corrupted, perform controlled reference run using REF function for affected axes.
Check encoder battery voltage (MP6610) if position corruption occurs frequently
Call a technician if:
- ·PLC program modifications required
- ·Encoder system malfunction suspected
- ·Machine parameter changes needed
Prevention
- Regularly validate NC program parameters before execution
- Implement program verification routines
- Monitor encoder battery levels quarterly
Common Mistakes
- Ignoring software travel limit warnings
- Modifying machine parameters without documentation
- Using excessive feed rate override values
