www.PLC S120 调试故障排除 F7902：Motor stalled www.PLC Function diagrams (see SINAMICS S120/S150 List Manual) 6730 Current control 8012 Torque messages, motor blocked/stalled Overview of important parameters (see SINAMICS S120/S150 List Manual) p1744 Motor model speed threshold stall detection p1745 Motor model fault threshold value stall detection p1755 Motor model without encoder, changeover speed p1756 Motor model changeover speed hysteresis p2178 Motor stalled delay time 调试时将绞车停滞延迟时间P2178 从0.176 修改为0.85 对于转盘来说必须使扭矩门限值P2174 大于零，否则会报F7902 www.PLC F7900:Motor Block www.PLC Function diagrams (see SINAMICS S120/S150 List Manual) 8012 Torque messages, motor blocked/stalled Overview of important parameters (see SINAMICS S120/S150 List Manual) p2175 Motor blocked speed threshold p2177 Motor blocked delay time 对于RT 来说由于转盘倒转的问题存在所以必须屏蔽此故障将R2175 设置为零即 可。 F31118：Encoder 1: Speed difference outside the tolerance range For an HTL/TTL encoder, the speed difference has exceeded the value in p0492 over several sampling cycles. 现场在绞车高速时报过此故障。解决方法将P0492 www.PLC 放大至200 。 调试时的注意事项：（对于STARTER ） 1. 对于 4.1 版本的 STARTER 来说在基本配置完成后需要选择逆变器 Configuration － Motor data － Motor/control parameters 中的 Complete calcaulation 并点击 Edit 。然后再将Project 下载至CU320 中。上线后必须将 逆变器的P10 参数由原来的Motor commissioning （3 ）改为Ready （0 ）。
