问题描述与安全警告
Yaskawa A1000 AC Drive 触发了严重的 Current Offset Fault 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
Code type: Fault Manual section: Yaskawa A1000 Troubleshooting Due to residual induction current in the motor when the drive attempted to start the motor, the drive attempted to adjust the current offset value beyond the allowable range. - Create a motor restart sequence that allows enough time for the residual induction voltage to dissipate. - Enable Speed Search at start (b3-01 = 1). Use the multi-function terminals to execute External Speed Search 1 and 2 (H1-□□ = 61 or 62). Note: When using a PM motor, both External Speed Search 1 and 2 perform the same operation. Hardware is damaged. Replace the drive. Replace the drive.
