126: Internal communication error (CP32)
127: Firmware version error (CP33)
128: Over-torque 3 (ot3)
129: Over-torque 4 (ot4)
134: Electronic thermal relay 3 protection (EoL3)
135: Electronic thermal relay 4 protection (EoL4)
140: oc hardware error (Hd6)
141: GFF occurs before run (b4GFF)
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)
 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 and Pr.14-70–Pr.14-73 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.
