Hello you will see what current is flowing into the motor and what it is nominally. if necessary, raise current limit P640.

Look at P0290, the MM4 will reduce frequency in overload conditions, to avoid this set P290 to 1. AttachmentMM4 P0290.pdf (581 Downloads) |

Hello, I decrease the P0640 value to 60% as the default value is 150% but the warning appears quickly but as warning generates it reduced the output frequency. |
