Workpiece probe data incorrect or inactive
Siemens · SINUMERIK 828D
¿Qué significa 61427 ?
The tool data for the active workpiece probe is either incorrect or the probe itself is inactive. This prevents accurate measurement operations. The error code (%4) indicates if the workpiece probe (or tool edge) is inactive, or if the length L1 of the workpiece probe is set to zero.
Causas comunes
- Workpiece probe tool data (e.g., T-number, D-number, probe length/diameter) in the tool management system is missing or incorrect.
- Workpiece probe is physically damaged (e.g., stylus broken, internal wiring fault) or not properly mounted/connected to the measurement system.
- Probe activation sequence or M-function for enabling the probe (e.g., M-code for probe power-on) is not executed or fails.
- Parameters for workpiece probe functionality (e.g., MD20070 for probe type, MD20080 for measurement speed) are incorrectly configured.
- Signal path from the probe to the NC (e.g., wireless receiver fault, cable break, PLC input module error) is interrupted or noisy.

- 1
1. Check the tool management system for the active workpiece probe's T-number and D-number, verifying that all offset values (length, radius) are accurately entered.
- 2
2. Visually inspect the workpiece probe and its stylus for damage, and confirm it is securely mounted and clean.
- 3
3. Verify the M-function (e.g., M70, M71) or PLC output signal responsible for activating the probe, ensuring it is energized (e.g., 24VDC at the probe receiver).
- 4
4. Execute a probe calibration routine (if available) to test its functionality and update its offset data.
- 5
5. Check parameters related to the workpiece probe (e.g., MD20070 for probe type, MD20080 for probe measuring speed) against the probe's specifications.
