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.

Pasos de reparación & Lista de verificación

  1. 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

    2. Visually inspect the workpiece probe and its stylus for damage, and confirm it is securely mounted and clean.

  3. 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

    4. Execute a probe calibration routine (if available) to test its functionality and update its offset data.

  5. 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.
