问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive: Power unit has been changed 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: Parameter: %1 Drive object: A_INF, B_INF, S_INF Reaction: NONE Acknowledge: IMMEDIATELY Cause: The code number of the current power unit does not match the saved number. The fault only occurs if the comparator in p9906 or p9908 is not at f 2 (low) or 3 (minimum). Fault value (r0949, interpret decimal): Number of the incorrect parameter. See also: r0200 (Power unit current code number), p0201 (Power unit code number) Remedy: Connect the original power unit and power up the Control Unit again (POWER ON) or set p0201 to r0200 and exit commissioning with p0010 = 0. For infeeds, the following applies: Commutating reactors or line filters must be used t hat are specified for the new power unit. A line supply and DC link identification routine (p3410 = 5) must then be carried out. It is not possible to change the power unit without re-commissioning the system if the type of infeed (A_Infeed, B_Infeed, S_Infeed), the type of construction/design (booksize, chassis) or the voltage class differ between the old and new power units. For inverters, the following applies: If the new power unit is accepted, then if required, the current limit p0640 can be reduced by a lower maximum current of the power unit (r0209) (torque limits stay the same). If not only the power unit is changed, but also t he motor, then the motor must be re-commissioning (e.g. using p0010 = 1). This is also necessary if motor data is still to be downloaded via DRIVE-CLiQ. See also: r0200 (Power unit current code number)
