<1> Displayed as CPF00 or CPF20 when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the display
will show CPF01 or CPF21.
<2> 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.
<3> Fault trace (i.e., the fault history) is not kept when CPF00, CPF01, CPF06, CPF24, Fdv, oFA00, oFb00, oFC00, Uv1, Uv2, and Uv3 occur.
