Common Causes

• Missing end orientation specification in G code block with taper circumference interpolation active
• Incomplete orientation programming when using ORIAXES or ORIROT commands without final orientation values
• Mixing orientation modes without clearly defining endpoint orientation in the taper interpolation sequence
• G code syntax error where orientation parameters are omitted in the interpolation block

Troubleshooting Steps

1. 1Review the G code block referenced in the alarm message to verify end orientation is explicitly programmed using appropriate orientation commands (A, B, C angles or ORIAXES/ORIROT parameters)
2. 2Confirm taper circumference interpolation mode is active and check that the orientation change is fully defined from start to end orientation within the same block
3. 3Verify the part program syntax matches the machine configuration for orientation specification; consult the machine's G code programming manual for correct taper interpolation syntax
4. 4Add the missing end orientation values to the identified block and retransmit the program to the CNC
5. 5Test with a simple orientation block without taper interpolation to isolate whether the issue is mode-specific or a general programming error
