代码 STo: Motor Pull Out or Step Out Detection
问题描述与安全警告
Yaskawa A1000 AC Drive 触发了严重的 Motor Pull Out or Step Out Detection 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 The wrong motor code is set (Yaskawa motors only). - Enter the correct motor code for the PM being used into E5-01. - For special-purpose motors, enter the correct data to all E5 parameters according to the test report provided for the motor. Load is too heavy. - Increase the load inertia for PM motor (n8-55). - Increase the pull-in current during accel/decel (n8-51). - Reduce the load. - Increase the motor or drive capacity. Load inertia is too heavy. Increase the load inertia for PM motor (n8-55). Acceleration and deceleration times are too short. - Increase the acceleration and deceleration times (C1-01 through C1-08). - Increase the S-curve acceleration and deceleration times (C2-01). Speed response is too slow. Increase the load inertia for PM motor (n8-55).
