142: Auto-tuning error 1 (no feedback current error) (AUE1)
143: Auto-tuning error 2 (motor phase loss error) (AUE2)
144: Auto-tuning error 3 (no-load current I
148: Auto-tuning error (leakage inductance Lsigma measuring error) (AUE4)
 When the fault occurs and forces stopping, the fault is recorded in this parameter.
 During stop with low voltage Lv (LvS warning), there is no error record. During operation with
mid-low voltage Lv (LvA, Lvd, Lvn error), there is a record.
 When dEb function is valid and enabled, the drive executes dEb and records fault code 62 to Pr.
06-17–Pr. 06-22 simultaneously.

 Use these parameters with multi-function output terminal (set to 35–38) for the specific
requirement. When the fault occurs, the corresponding terminals activate. Convert the binary
value to decimal value before you enter the value for Pr. 06-23–Pr. 06-26.
