How much is the length of motor cable? Check the power cable shielding ground connection at drive end. It must be tight & perfect. In some cases, lekage current gets path via shield to drive end which could cause such probelms. I suggest you to check motor IR value & check motor power cable shield connection. You can try by replacing DMM but confirm its article number is same. To do so, refer this post.. Before following below procedure please check if drive safety is activated. HTH. |

CU unit is integrated in NCU. Sinamics series has separate CU unit & all Sinamics related parameters are stored in CU. Depending upon parameter setiing, actual & target topology is comapred as per level set. So when you replace any component, if mismatch is observed, CU trigers fault. So you need to carry out parameter setting or identification or reconfugartion when you replace any component. You can check CU parameters under page CU in machine data tab. Please refer Replacement of S120 componenets topic which may help you. HTH. |
