80: V-phase over-current before run (Voc)
81: W-phase over-current before run (Woc)
82:
U-phase output phase loss (OPHL)
83: V-phase output phase loss (OPHL)
84: W-phase output phase loss (OPHL)
87: Drive overload in low frequency (oL3)
89: Initial rotor position detection error (RoPd)
140:
GFF detected when power ON (Hd6)
141: GFF before run (BGFF)
142:
Auto-tuning error 1 (DC test stage) (AUE1)
143:
Auto-tuning error 2 (high frequency test stage) (AUE2)
144:
Auto-tuning error 3 (rotary test stage) (AUE3)
The system records the fault as long as the fault is forced to stop.
Low voltage (Lv) when stopped (LvS warning, no record); low voltage (Lv) when operating (LvA,
Lvd, Lvn error, recorded by the system).
When the dEb function is effective and enabled, the drive starts the dEb function and also
records the fault code 62 to Pr.06-17–06-22, Pr.14-70–14-73 at the same time.
