I68 max invert/convert errors #47

Closed awattsFNAL closed 2 months ago

awattsFNAL commented 7 months ago

I68, the application that builds the reference waveforms for many large magnet power supplies, is not allowing new waveform ramps to be generated due to an error with the maximum voltage slew rate settings.

awattsFNAL commented 7 months ago

Images from Max Monnigh below. I68 isn't allowing new ramp generation because the convert/invert rates (i.e. voltage slew up and down rates) exceed the maximum settings. What changed? Was it related to the database switchover? Note that PESD folks must be consulted if we need to change the max invert/convert values, as they're related to the specific power supply's capability.

Reached out to Denise, Jim S., John Devoy, and John Diamond. Will assign issue accordingly.

Max M. and Matt K. discovered that V108 was misconfigured in the application (wrong supply type). Working with John DeVoy to verify that there's no issue with the application database.

V108 and LAM52 now have updated hardware parameters from PESD, and can successfully write ramps that look reasonable. HV703 still needs new parameters, and PESD may need to make measurements to determine them.
