ME300
52: Password is locked (Pcod)
54: Illegal command (CE1)
55: Illegal data address (CE2)
56: Illegal data value (CE3)
57: Data is written to read-only address (CE4)
58: Modbus transmission time-out (CE10)
63: Over-slip (oSL)
72: S1 internal loop detection error (STL1)
76: STO (STo)
77: S2 internal loop detection error (STL2)
78: S3 internal loop detection error (STL3)
82: Output phase loss U phase (OPL1)
83: Output phase loss V phase (OPL2)
84: Output phase loss W phase (OPL3)
87: Overload protection at low frequency (oL3)
142: Auto-tuning error 1 (DC test stage) (AUE1)
143: Auto-tuning error 2 (high frequency test stage) (AUE2)
149: Total resistance measurement fault (AUE5)
150: No-load current IO measurement fault (AUE6)
151: dq axis inductance measurement fault (AUE7)
152: High frequency injection measurement fault (AUE8)
157: Pump PID feedback error (dEv)
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–Pr.06-22, Pr.14-70–Pr.14-73 at the same time.
