代码 230002: <location>Power unit: DC link voltage, overvoltage
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Power unit: DC link voltage, overvoltage 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: %1 Drive object: All objects Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The power unit has detected an over voltage condition in the DC link. - motor regenerates too much energy. - device supply voltage too high. - when operating with a VSM, the phase assignment L1, L2, L3 at the VSM differs from the phase assignment at the power unit. Fault value (r0949, interpret decimal): DC link voltage [1 bit = 100 mV]. For SINAMICS GM/SM, the following applies: Fault value (r0949, interpret decimal): 32: Overvoltage in the negative partial DC link (VdcP) 64: Overvoltage in the positive partial DC link (VdcN) 96: Overvoltage in both partial DC links SINAMICS-Alarms Remedy: - increase the ramp-down time. - activate the DC link voltage controller. - use a brake resistor or Active Line Module. - increase the current limit of the infeed or us e a larger module (for the Active Line Module). - check the device supply voltage. - check and correct the phase assignment at the VSM and at the power unit.
