What causes Siemens SINUMERIK alarm 14101?

TRAORI instruction missing or not called before orientation commands in the NC program. Incorrect transformation grouping number specified in TRAORI(n) - mismatch between defined and active transformation. Orientation specification using Euler angles or vector notation without active 5-axis transformation. Program block contains ORIWKS or similar orientation commands before TRAORI activation. Transformation was deactivated or reset prior to orientation block execution.

How do I fix Siemens SINUMERIK alarm 14101?

1. Review the NC program structure - locate the orientation command (ORIWKS, Euler angles, or vector notation) and verify TRAORI(n) is called in a preceding block with appropriate grouping number 2. Confirm the transformation grouping number used in TRAORI(n) matches the transformation definition in the machine parameter settings and post-processor configuration 3. Insert TRAORI(n) instruction before the first orientation-dependent block; verify syntax matches N100 TRAORI(1) format shown in alarm description example 4. Check if a TRAFOOF or similar deactivation command was executed after TRAORI - reposition TRAORI call after any deactivation blocks if present 5. Simulate or dry-run the corrected program to confirm alarm clears and orientation transformation activates without secondary errors

Alarm 14101

Siemens 840D 14101 - Channel block orientation transformation not active

Euler angles or a vector have been used in programming an orientation and no orientation transformation is active, i.e. the keyword TRAORI(n) (n. number of transformation grouping) is missing. Example of correct transformation programming: N100. TRAORI(1) N110 G01 X. Y. ORIWKS N120 A3. B

Common Causes

TRAORI instruction missing or not called before orientation commands in the NC program
Incorrect transformation grouping number specified in TRAORI(n) - mismatch between defined and active transformation
Orientation specification using Euler angles or vector notation without active 5-axis transformation
Program block contains ORIWKS or similar orientation commands before TRAORI activation
Transformation was deactivated or reset prior to orientation block execution

Troubleshooting Steps

1Review the NC program structure - locate the orientation command (ORIWKS, Euler angles, or vector notation) and verify TRAORI(n) is called in a preceding block with appropriate grouping number
2Confirm the transformation grouping number used in TRAORI(n) matches the transformation definition in the machine parameter settings and post-processor configuration
3Insert TRAORI(n) instruction before the first orientation-dependent block; verify syntax matches N100 TRAORI(1) format shown in alarm description example
4Check if a TRAFOOF or similar deactivation command was executed after TRAORI - reposition TRAORI call after any deactivation blocks if present
5Simulate or dry-run the corrected program to confirm alarm clears and orientation transformation activates without secondary errors
