Siemens 840D 15910 - Channel block touch probe not allowed

Measure without deletion of distance-to-go In the part program, an illegal probe has been programmed with the command MEAW (measure without distance-to-go). The probe numbers 0. no probe 1. probe 1 2. probe 2 are allowed, whether the probe is actually connected or not. Example: N10 MEAW=2 G

Siemens 840D 15910 - Channel block touch probe not allowed

Channel block touch probe not allowed

Measure without deletion of distance-to-go In the part program, an illegal probe has been programmed with the command MEAW (measure without distance-to-go). The probe numbers 0. no probe 1. probe 1 2. probe 2 are allowed, whether the probe is actually connected or not. Example: N10 MEAW=2 G

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • MEAW command programmed with invalid probe number (only 0, 1, or 2 allowed)
  • Probe number argument exceeds maximum allowed value in part program
  • Syntax error in MEAW command preventing proper probe number parsing
  • Machine configuration does not support the specified probe number despite programming attempt

Troubleshooting Steps

  1. 1Review the part program at the specified block number and verify MEAW command syntax matches allowed format (MEAW=0, MEAW=1, or MEAW=2)
  2. 2Check that probe number argument is a single digit integer between 0 and 2; correct any values outside this range
  3. 3Verify machine configuration and probe hardware setup matches the probe numbers referenced in the program
  4. 4Confirm MEAW command placement and context within the NC program does not conflict with other active commands or machine states
  5. 5Recompile or reload the corrected part program and test with a dry run before executing
