問題描述與安全警告
Siemens SINUMERIK 840D CNC 觸發了嚴重的 Normalizing machine data has been changed 警報。需要由合格的操作員或維修技師立即處理,以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前,請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
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.
