Code voF (Fault): Output Voltage Detection Fault

Code type: Fault Manual section: Yaskawa A1000 Troubleshooting Hardware is damaged. Replace either the control board or the entire drive. For instructions on replacing the control board, contact Yaskawa or your nearest sales representative. <1> Displayed as or when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the display will show or. <2> Occurs in models CIMR-A□4A0930 and 4A1200. <3> This function prevents continuous operation in reverse when using high frequency injection (n8-57 = 1) in the Advanced Open Loop Vector Control mode for PM motors (A1-02 = 6) with a motor for which no motor code has been entered (it does not simply prevent reverse operation). To quickly detect undesirable reverse operation, set L8-93, L8-94, and L8-95 to low values within range of erroneous detection.
