问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 Axis %1 difference in function safe velocity %2, NCK: %3 drive: %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 = Axis number %2 = SG level for which the difference was determined %3 = Monitoring status safe velocity %4 = Monitoring status safe velocity Definitions: During cross-comparison of result list 1 a differ ence was detected between the NCK and drive monitoring channels in the status of safe velocity monitoring. - Safe velocity 1: Bit 6, 7 in result list 1 - Safe velocity 2: Bit 8, 9 in result list 1 - Safe velocity 3: Bit 10, 11 in result list 1 - Safe velocity 4: Bit 12, 13 in result list 1 Monitoring status (%3, %4): - OFF = Monitoring is inactive in this monitoring channel - OK = Monitoring is active in this moni toring channel, limit val ues are not violated - L+ = Monitoring is active in th is monitoring channel, upper limit exceeded - L- = Monitoring is active in this monitoring channel, lower limit exceeded Reaction: Alarm display. If a safe monitoring was active, STOP B was also triggered automat ically. In this case, a power OFF/ON of the control will be required. Remedy: Check whether the safe inputs have switched to the same status in both monitoring channels within the permissible time tolerance. For further diagnostics, the drive parameters r9710[0], r9710[1] and the servo trace signals "Result list 1 NCK" and "Result list 1 drive" can be used. Program Continuation: Clear alarm with the RESET key. Restart part program
