问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 [Channel %1: ] Block %2 channel-specific protection zone %3 cannot be activated. Error code %4 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
Parameters: %1 = Channel number %2 = Block number, label %3 = Number of the channel -specific protection zone %4 = Error specification Definitions: An error has occurred on activating the protection zone. The error number gives the specific reason for the alarm. No.Meaning 1: Incomplete or conflicting contour definition. 2: Contour encompasses more than one surface area. 3: Tool-related protection zone is not convex. 4: If both boundaries are active in the 3rd dimens ion of the protection zone and both limits have the same value. 5: The number of the protection zone does not exist (negative number, zero or greater than the maximum number of protection zones). 6: Protection zone definition consists of more than 10 contour elements. 7: Tool-related protection zone is defined as insi de protection zone. 8: Incorrect parameter used. 9: Protection zone to be activated is not defined or number of the contour element <2 or >MAXNUM_CONTOURNO_PROTECTAREA. 10: Error in internal structure of the protection zones. 11: Other, not further specified errors. 12: The number of protection zones simultaneously active exceeds the maximum number (channelspecific machine data). 13,14: Contour element for protection zones cannot be created. 15,16: No more memory space for the protection zones. 17: No more memory space for the contour elements. Reaction: Correction block is reorganized. Interface signals are set. Alarm display. If the alarm is output on ramp-up (2nd parameter: "I NIT" instead of block number), "Channel not ready to operate" will be set. Remedy: Please inform authorized perso nnel / the service department. 1. Reduce the number of simultaneously active protection zones (MD). 2. Modify part program: - Delete other protection zones. - Preprocessing stop. When the alarm occurs on control ramp-up, system variables $SC_PA_... must be corrected for the specified protection zone. Afterwar ds perform a restart. If the erroneous data cannot be recognized, the protection zone's immediate ac tivation can be removed, and the system variables of the protection zone can be written again by means of CPROTDEF. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program. The current block can be changed if the alarm occu rs during NC program execution. The CPROT parameters can also be adjusted. However, if the erro r lies in the definition of the protection zone, the NC program must be aborted and the definition corrected under CPROTDEF. If the alarm occurs on control power-up, the sys tem variables $SC_PA_... must be corrected for the specified protection zone. This can be done by downloading an Initial.ini file that includes the relevant corrected data. If another restart is then made, t he alarm will have been eliminated provided that the data are now consistent.
