First assumption : you didn't count the correct number of pulses per turn. Look at one of the two signals and count only positive edges. There is no tolerance on this parameter (numimp) it must be spt on


This was the case. I noticed the numimp was actually the default value, maybe i just forgot ...

As the title says, my car is accelerating when it tries to regen. Happens with sine firmware 5.27R and 5.35R.

I have three suspects:

Inverter configuration is wrong. I followed the tuning guide to set it up initially. https://openinverter.org/wiki/Parameters#Tuning_Guide

Encoder on the motor. No ...

Good to hear it is working normally. I was using fslipspnt=10. I suppose the small motor has a large winding resistance and needs more voltage to spin unloaded, compared to a bigger motor.

I was testing my inverter today, and got confused. I was following the guide on the wiki (https://openinverter.org/wiki/Schematics_and_Instructions) which went smoothly until i connected the motor:
It wouldn't spin and with input of 50v DC i was only seeing around 2v AC on the inverter outputs. The ...
