问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Infeed: Maximum steady-state DC link voltage reached 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
Message value: Drive object: A_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: The DC link voltage setpoint has reached the ma ximum steady-state voltage parameterized in p0280. The DC link voltage is increased by the modulation d epth reserve controller for the following reasons: - modulation depth reserve is too low (p3480). - line supply voltage is too high. - supply voltage (p0210) parameterized to be too low. - excessively high setpoint fo r the reactive line current. Remedy: - check the line supply voltage setting (p0210). - check the line supply for an overvoltage condition. - reduce the modulation depth reserve (p3480). - reduce the reactive current setpoint.
