问题描述与安全警告
Chiron Siemens-Control CNC 触发了严重的 A-axis clamping not clamped 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
Actuation "Clamp A-axis clamping" was output, but the axis clamping is not yet clamped or still signals unclamped. PLC input signal "A-axis clamping clamped" is not registered. PLC input signal "A-axis clamping unclamped" is still registered. The error has the following effect: Feed Stop No axis movements possible. Read disable Control reads no further program blocks into memory. If the sensor signals are correct within a monitoring period, the program run is continued. After the monitoring time has elapsed, the machine stops. 1. Check the PLC input signals "A-axis clamping unclamped", "A-axis clamping clamped" and the pressure sensors. 2. Check the PLC output signals "Unclamp A-axis clamping", "Clamp A-axis clamping" and the valves. 3. Once the malfunction has been remedied, press [FEED START]. Message is cleared.
