P and D gains setting check (problem).
Position P-gain = 12673
Position D-gain = 16000
Position I-gain = 0
Position I-limit = 0
Problem: Noticeable oscillation (Channel 1) on Iq current waveform.
Treatment: Decrease the P-gain setting until oscillation disappears.
S945
P and D gains setting check (corrected)
Position P-gain = 12673
Position D-gain = 16000
Position I-gain = 0
Position I-limit = 0
Positive effect:
Oscillation stopped and stability is increased
