text: <s>[INST] Powerflex700L Frame 2 Intermittent NTC Fault Hi All, One of our customers is using a 700L frame 2 drive. He has been facing NTC fault intermittently. Any idea on what could be the probable causes & checkpoints. [/INST] https://literature.rockwellautomation.com/idc/groups/literature/documents/um/pflex-um002_-en-p.pdf Active Converter Module shows 8 different IGBT temperatures (P330-P333, P335-P338), 2 faults (64 low, 65 high). Resolution for both NTC faults is to check the NTC sensors for open circuit or short circuit. Are you getting one of those two faults? https://literature.rockwellautomation.com/idc/groups/literature/documents/um/20l-um001_-en-p.pdf This document says F192 is NTC sensor failed and to contact Rockwell Technical Support. In all failure codes listed in these two documents, there's not much you can do besides replace the NTC sensors.
