代码 4070: Normalizing machine data has been changed
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 Normalizing machine data has been changed 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Definitions: The control uses internal physical units (mm, degrees, s, for paths, velocities, acceleration, etc.). During programming or data storage, some of these va lues are input and output using different units (rev./min, m/s2, etc.). The conversion is carried out with the scaling factor s that can be entered (system-spefic MD array MD10230 $MN_SCALING_FACTORS_USER_DEF USER_DEF[n] (n... index number 0 - 10), when the corresponding masking bit is set to "1". If the masking bit is set to "0" then scaling takes place with the internal standard factors. The following machine data influence the scaling of other MDs: MD10220: $MN_SCALING_USER_DEF_MASK MD10230: $MN_SCALING_FACTORS_USER_DEF MD10240: $MN_SCALING_SYSTEM_IS_METRIC MD10250: $MN_SCALING_VALUE_INCH MD30300: $MA_IS_ROT_AX If these data are modified, the NCK must be power ed up again. Only then will the input of dependent data be performed correctly. Reaction: Alarm display. Remedy: Please inform the authorized personnel/service department. If the alarm has been displayed after downloading an MD file which is consistent within itself, then the download operation must be repeated with a new NC power-up. (The file contains scaling-dependent machine data in front of the scaling factors). Program Continuation: Clear alarm with the Delete key or NC START.
