61341

Siemens 840D 61341 - Channel block: Probe not calibrated in active plane.

Channel block: Probe not calibrated in active plane.

The alarm is triggerd by the following cycles: CYCLE974, CYCLE977, CYCLE978, CYCLE979. Remedy: Calibrate the probe prior to calling a cycle.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Probe calibration data missing or cleared for the active working plane
  • Incorrect plane selection (G17, G18, G19) before probe cycle execution
  • Probe offset parameters not initialized after system restart or parameter reset
  • Switching between different probes without recalibrating for the new probe geometry

Troubleshooting Steps

  1. 1Verify the active plane selection in the NC program matches the probe calibration plane using G17 (XY), G18 (XZ), or G19 (YZ) commands
  2. 2Execute the appropriate probe calibration cycle (CYCLE974 or equivalent) in the required plane before running CYCLE977, CYCLE978, or CYCLE979
  3. 3Check machine parameter settings for probe offset storage and confirm calibration values are retained in the system memory
  4. 4Clear any pending alarms and restart the probe initialization sequence, ensuring the probe makes proper contact with the calibration block
  5. 5Review the NC program logic to ensure plane selection occurs before probe calibration and probe-dependent cycles are called in the correct sequence
