Tool data of the active workpiece probe incorrect or inactive
Siemens · DAsl Diagnostics and Alarms
What does 61427 mean?
The workpiece probe or its tool edge data is either inactive or contains incorrect values, specifically if the length L1 is zero. This issue prevents the system from accurately using the probe for measurement or calibration, potentially causing measurement errors or collisions. The error code A indicates an inactive probe/tool edge, while B indicates L1 is zero.
Common Causes
- Workpiece probe data (e.g., length L1) is set to zero or invalid values in the tool offset memory.
- The active tool number (T-number) does not correspond to a valid workpiece probe in the tool table.
- Probe activation signal (e.g., PLC input) is not correctly registered by the NCU.
- Incorrect probe orientation or wear compensation parameters in the tool management system.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Access the HMI tool management system and verify the L1 length parameter for the active probe tool (e.g., T101, D1).
- 2
Ensure the workpiece probe is correctly selected and active (e.g., T-number matches mounted probe).
- 3
Check parameter P4190 (Probe selection) to ensure the correct probe type is assigned.
- 4
Perform a probe calibration cycle using a known reference artifact to re-establish L1 and R values.
- 5
Verify the PLC program logic for probe activation and data transfer to the NCU.
