Hello, What? explains better your problem, you have removed the IGBTs and want to run the Micromaster without IGBT? What you put in its place? |

The way you want to do it, is not possible. Before you can use the drive (e.g. for measurements) the IGBT has to be replaced and calibrated. And that should be down only by a certificated Siemens Partner Repair Shop! (how to find? see link: http://w3.siemens.com/aspa_app/?nodekey=key_9177773&lang=en) |

New question published by mr.adi is split to a separate thread with the subject MM440, a0503 appeared and than turns off. Best regards |
