Which faults on the ATV66 require manual reset and, which ones can be reset by logic input, function key or automatically?

    The faults resettable Only By Manual Reset (Removal of Power) are Short circuit, Ground fault, Precharge failure, Internal fault, Memory failure, Dynamic brake fault, Dynamic brake resistor fault, Auto-test failure, Transistor short circuit, Open transistor and Link fault
    Faults Reset by LI, Function Key, or Manual Reset are AC line overvoltage, DC bus overvoltage, Sequence time-out fault, Overspeed, Output phase loss, programmable fault stop (custom fault or customer defined fault), Drive overtemperature, Motor overload, Loss of follower, Process time-out fault and Serial link fault.
    Faults that can be Automatically Reset are AC line overvoltage, DC bus overvoltage, Sequence time-out fault, Overspeed, Output phase loss, programmable fault stop (custom fault or customer defined fault), Drive overtemperature, Motor overload, Loss of follower, Process time-out fault and Serial link fault. This requires that auto reset be enabled and the fault condition to clear.
    Non-Latching fault [see note 1] are Undervoltage, programmable fault stop (custom fault or customer defined fault) and input phase failure.

FOOTNOTE [1] When the fault condition is no longer present , the drive controller will automatically restart the motor if the Command Type is set for 2-wire and the Run Enable and direction inputs are maintained, regardless of the setting of Automatic Restart.
