Hey I'm setting up a powerflex 755T, but in the connected components wizard during startup, I'm getting an issue where next to the start button it says "P603 Start Inhibits", this led us to page 25 on https://literature.rockwellautomation.com/idc/groups/literature/documents/um/750-um004_-en-p.pdf

"f STO is performed, the Start Inhibits parameter indicates the IGBTs are inhibited, and the HIM
indicates that the drive is not enabled. The Start Inhibits parameter is parameter 933 in
PowerFlex® 755 drives and parameter 603 in PowerFlex 755T drive products."



and while looking through that information, we also found page 77 on: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm101_-en-p.pdf


Our STS light is flashing yellow, as far as I know (which isn't much) there's no faults or alarms running, but the STS light flashing allegedly means that there is an alarm running according to:
https://www.manualslib.com/manual/1351153/Allen-Bradley-Powerflex-755t.html?page=79


I'm lost guys 🙃
 
Are you using the safety inputs for the STO function, or is the jumper still installed. One or the other needs to be in use or start will be "inhibited".
