问题描述与安全警告
Yaskawa A1000 AC Drive 触发了严重的 Overspeed 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: Alarm / minor fault Manual section: Yaskawa A1000 Troubleshooting Overshoot is occurring. - Increase the settings for C5-01 (Speed Control Proportional Gain 1) and reduce C5-02 (Speed Control Integral Time 1). - If using a Closed Loop Vector mode enable Feed Forward Control and perform Inertia Auto-Tuning. YES Incorrect speed feedback scaling if terminal RP is used as speed feedback input in V/f control - Set H6-02 to value of the speed feedback signal frequency when the motor runs at the maximum speed. - Adjust the input signal using parameters H6-03 through H6-05. Incorrect PG pulse number has been set Check and correct parameter F1-01. Inappropriate parameter settings. Check the setting for the overspeed detection level and the overspeed detection time (F1-08 and F1-09).
