Sync losses on regenerative when voltage is close to upper limit #127

Open ddosoff opened 4 years ago

ddosoff commented 4 years ago

Recently I found that in case of rotating against applied current which cause regenerative braking no fault code emitted but sync losses. Sometimes only tachometer steps goes wrong, sometimes motor becomes released.

After discharging battery down from the limit everything is ok.

Is this with or without sensors, and how fast is the motor rotating?

I have hall sensored 4kw qs-motor. I investigated a bit more and found that fault code emitted for short period. Most important issue that tachometer value becomes wrong.
