Siemens 840D 4070 - Normalizing machine data has been changed

The control uses internal physical units (mm, degrees, s, for paths, velocities, acceleration, etc.). During programming or data storage, some of these values are input and output using different units (rev./min, m/s2, etc.). The conversion is carried out with the scaling factors that can be entered

Normalizing machine data has been changed

The control uses internal physical units (mm, degrees, s, for paths, velocities, acceleration, etc.). During programming or data storage, some of these values are input and output using different units (rev./min, m/s2, etc.). The conversion is carried out with the scaling factors that can be entered

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Machine data scaling factors modified without proper documentation or verification
  • Inconsistent unit conversion between programming interface and control system
  • Backup/restore operation applied incorrect machine data parameter set
  • Third-party software or CAM system using non-standard scaling conventions
  • Manual editing of machine data files without recalculation of dependent parameters

Troubleshooting Steps

  1. 1Verify current machine data scaling factors against original equipment documentation and compare with backup data from last known good configuration
  2. 2Check all axis parameter conversion ratios (feed rate, velocity, acceleration scaling) and confirm they match the physical machine specifications
  3. 3Review recent machine data modifications in the audit trail or version history to identify when normalizing values were changed
  4. 4Recalculate and re-enter all affected machine data parameters using consistent internal units (mm, degrees, seconds) with proper scaling factors
  5. 5Perform a complete machine data reload from verified backup or re-enter parameters manually, then execute reference point positioning and test with a simple program
