Re: Mainboard V3 FAQ
The inverter kit uses an analog isolator and resistor divider to measure voltage. https://openinverter.org/wiki/Sense_Boards

Re: Motor pulling high current at startup [SOLVED]
Well... It looks like I'm having more issues with slip control mode. I will document my previous problem and its fixes. In slip mode, the motor will not spin until I reach a potnom of 60%. And about 50% of the time it instantly hits overcurrent when I send "start 1" even when at zero throt...

Re: Motor pulling high current at startup [SOLVED]
The first thing you want to do for testing the encoder is turn the motor by hand with the hv turned off and inverter logic powered. Check on the pins of the stm32 that the signals are reaching the processor. Yup I've verified that. Signals look nice. That is what you expect. In manual mode there is...

Re: Motor pulling high current at startup [SOLVED]
That got it working! With fweak = 100, I can run at 57v and 114v at ocurlim = 200. The motor spins up very smoothly and quietly. With encoder connected, however, the motor begins to jump a bit every rotation. It also draws 3 times the phase current (measured with clamp meter over phase cables - 30a ...

Motor pulling high current at startup [SOLVED]
Hi, I have a Rev2 inverter kit with a DMOC645 power stage - CM600DY-12NF IGBTs. I have a Siemens 1PV5135 motor. This is a ~60kw industrial style ACIM, nominal voltage about 250V. I don't have any other specs on it. I've been trying to work through the Schematics and Instructions guide on the wiki. C...

Re: Future of the inverter kit
I have a DMOC power stage and am planning on buying either the v2 or v3 inverter kit.
Which is better?
Or can I purchase a blue pill board now?
I'm planning to buy within the next couple of weeks
EDIT: My motor (Siemens 1pv5135) has a quadrature encoder if that makes any difference.
Thanks
