Analyze shows that left point (X100) has smooth sinusoid (only few oscillations), but changing direction at 0 has more and bigger amplitudes.
It looks like that:
I have tried various paremeters, but without success.
0 --------- 100
Motor is "pancake" type, and table with specification is damaged, but I think is has 3000 rpm and 90V. I have tried various voltage, but only 16V and slow rev gave acceptable result.
A also have tried with other motors with known specification (24V) and try with voltage up to 30V (115% of nominal) but simptoms are the same.
Why my controller alway run left?
