Tool data of the active workpiece probe incorrect or inactive

What does 61427 mean?

This alarm signals that the data for the currently active workpiece probe is either incorrect or the probe itself is inactive. Error code 'A' indicates an inactive workpiece probe or tool edge, while 'B' signifies that the probe's length L1 is zero. This issue prevents accurate workpiece measurement and can lead to machining errors if not corrected, impacting precision and quality.

• Workpiece probe is not correctly activated or selected (indicated by error code 'A') in the NC program for measurement.
• Tool data (T-data) associated with the active workpiece probe contains incorrect or out-of-range values (e.g., probe length, diameter).
• Loss of communication or intermittent signal from the workpiece probe (e.g., low battery for wireless probes, damaged cable for wired probes).
• Incorrect parameterization of the probe's offset definition or activation sequence in the NC program or machine data.
• Physical damage or excessive wear to the probe stylus, affecting its measurement accuracy or ability to trigger reliably.

Click steps to track your progress.

1. 1

   1. Verify that the workpiece probe is correctly selected and activated in the NC program using the appropriate M-code or dedicated function.

2. 2

   2. Inspect the active tool data (T-data) for the workpiece probe, ensuring all values like length (L1, L2) and radius are accurate.

3. 3

   3. Check the communication link and power status (e.g., battery level for wireless probes, cable continuity for wired probes) of the workpiece probe.

4. 4

   4. Perform a manual probe trigger test to confirm the probe is mechanically sound and generates a signal upon contact.

5. 5

   5. Review and correct the machine data (MDs) or NC parameters that define the workpiece probe characteristics and measurement cycles.

6. 6

   6. If physical damage is suspected, replace the probe stylus or, if available, substitute with a known good workpiece probe for testing.
