What to do if ABB Media Converter shows speed feedback fault?
- SstevenkellerAug 16, 2025
If the ABB Media Converter displays a speed feedback fault, check the incremental encoder and connection cable, ensuring the encoder power supply provides adequate feedback. Verify the tacho polarity and voltage, and confirm the position of jumper S4 on board SDCS-CON-2. Inspect the electronic boards SDCS-CON-2, SDCS-IOB-3, and SDCS-POW 1. Also, check the connection between the converter and the armature circuit for any open connections. Finally, confirm the correct setting for the selection of speed feedback monitoring.
