问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive: Incorrect direction of rotation of the field or encoder actual value inversion 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: SERVO Reaction: OFF2 (NONE) Acknowledge: IMMEDIATELY Cause: Either the direction of the rotating field or the enc oder actual value has an incorrect sign. The motor data identification automati cally changed the actual value inversion (p0410) in order to correct the control sense. This can result in a direction of rotation change. To acknowledge this fault, the correctness of the direction of rotation must first be acknowledged with p1910 = -2. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: Check the direction of rotation, also for t he position controller, if one is being used. If the direction of rotation is correct, the following applies: No additional measures are required (e xcept p1910 = -2 and acknowledge fault). If the direction of rotation is incorrect, the following applies: To change the direction of rotation, two phases must be interchanged and the motor identification routine must be repeated.
