问题描述与安全警告
Yaskawa A1000 AC Drive 触发了严重的 Speed Deviation (when using a PG option card and AOLV/PM without PG) 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 Load is too heavy Reduce the load. Acceleration and deceleration times are set too short. Increase the acceleration and deceleration times (C1-01 through C1-08). The load is locked up. Check the machine. Parameter settings are inappropriate. Check the settings of parameters F1-10 and F1-11. 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 speed feedback signal using parameters H6-03 through H6-05. - Make sure the speed feedback signal frequency does not exceed he maximum input frequency of terminal RP. The motor brake engaged. Ensure the brake releases properly.
